The fight against harmful insects is an important component comprehensive care for ornamental, horticultural and agricultural crops. The most effective means for the destruction of pests are insecticides.
Exists a large number of preparations depending on the method of application, composition and active ingredient. In the article we will consider everything about the use of insecticides for the garden.
Insecticides (translated from Latin means "I kill insects") - this is a large group of drugs for the destruction of pests. For their manufacture, both chemical and biological substances are used. They act differently on insects, may have a limited or wide spectrum of action.
Depending on the composition, insecticides have 1-4 toxicity classes, so certain safety measures should be applied when using them.
What is it used for?
Such preparations are actively used for preventive and active pest control in the cultivation of most types of crops, ornamental plants. They are of great importance for agriculture.
Before using an insecticide, you need to carefully select the appropriate preparation, taking into account the type of insect, the concentration of the active substance and the area of \u200b\u200bapplication.
Varieties of drugs
To date, a huge number of insecticides have been developed. They are divided depending on the method of action on a harmful insect, according to composition. Also, there are several groups of specialized tools aimed at the prevention and destruction of specific types of pests. Consider the main types of funds.
Systemic or intraplant
The drug is absorbed along with water by the roots and leaves, and then moves through its vascular system of the plant. As a result, it becomes poisonous to insects.
The main advantages of such funds are the duration of action, as well as the ability to be used as a preventive measure, in all weather conditions. There is also a drawback - the impact on the pest occurs gradually, the reaction does not occur immediately.
The most effective systemic insecticides are made on the basis of imidacloprid, organophosphate poisons. List of systemic drugs:
- Aktara. It has a wide spectrum of action, is ineffective against ticks and whiteflies. It has an intestinal-contact effect on pests. Available in the form of granules or suspensions.
- Confidelin. Available in the form of a water-soluble suspension. It is used to fight and prevent insects and their larvae that eat the green parts of the plant. The active substance is imidacloprid.
- Bazudin. Effective remedy for the destruction of soil pests, decorative and garden plants. The active substance is diazinon.
Intestinal
Preparations of this group enter the body of the insect along with the eaten green parts, plant sap. They are used against pests with chewing or sucking mouthparts, most effective against various caterpillars, larvae and beetles.
They can also be used for preventive treatment. The result of the use of intestinal insecticides is highly dependent on weather conditions. Uniform processing is extremely important, since such preparations are not distributed in plant tissues.
Popular drugs:
- Chlorophos. Phosphorus organic agent with a specific odor. Usually used for processing fruit trees. The drug is effective against sawflies, caterpillars, codling moths and butterflies.
- wolaton. The active substance is phoxim. It has a wide spectrum of action against biting and sucking insects. The duration of the effect after treatment is only 5 days.
- Fozalon. A highly toxic drug with a long-term effect. It is used to destroy biting, sucking insects, it is ineffective against sawflies. After the agent enters the body of the pest, death occurs within 48 hours.
When working with intestinal insecticides, it is always important to take precautions, since some agents are toxic to humans and pets.
Contact
They enter the body of an insect through the skin, the action occurs through direct contact with the body of the pest. Careful processing of the entire landing area is required.
The result is highly dependent on weather conditions and compliance with the insecticide application technique. Some products are suitable for prevention against infection, but are partially washed off after precipitation, watering. As a rule, these are toxic organophosphorus compounds.
Common drugs:
- Inta-vir. Refers to insecticides of intestinal-contact action. Effective against various pests of indoor and garden plants. Destroys up to 52 varieties of insects. It has a wide spectrum of action, is available in the form of tablets or water-soluble powder.
- citkor. A tool for the fight against many types of pests of agricultural crops. Especially effective against the Colorado potato beetle, whiteflies and aphids. It has a long period of protective action, after treatment, the effect lasts up to 30 days. Non-toxic, has a stable contact-intestinal effect on pests.
- Actellik. It is a popular intestinal-contact insecticide. Effective against most types of harmful insects, ticks. Refers to organophosphorus drugs. Possesses the long period of protective action, is economic in use.
Such means are most often used to combat garden and ornamental pests. They have low toxicity, do not harm the health of plants, do not affect the taste characteristics of the crop.
Respiratory (fumigants)
current toxic substance enters the body of an insect in the process of respiration. The drug is used in gaseous or vapor form. Fumigants are not suitable for prevention, but are extremely effective for treating plants during a severe infection.
Often used to work with large areas of agricultural plantings, as well as for processing crops during storage.
Popular means:
- Magtoxin. Preparation for the treatment of stock pests, their larvae. It also actively fights ticks and moths. The active substance is magnesium phosphide, available in the form of tablets. The agent is able to penetrate even through the packaging material.
- Phostoxin. A product based on aluminum phosphide, used for processing granaries, warehouses for storing crops. It acts on all harmful insects, partially affects rodents. May penetrate packaging.
Fumigants are best used to treat warehouses and containers with crops that have been infested with pests. After use, the active substance may remain in the form of a precipitate on fruits and vegetables, so they must be thoroughly washed before use.
Bacterial insecticides
Apart from chemicals Biological insecticides are used to control and prevent pest infestation. These are ecological products created on the basis of strains of bacteria or viruses.
After processing, they have a delayed inhibitory effect on harmful insects. They are non-toxic, safe for humans and do not affect plant health.
Common means:
- Iskra-Bio. Contributes to the destruction of many varieties of pests, mites. It works especially effectively in hot weather, due to the safe composition, processing is possible several days before harvesting. It is used for vegetable and berry crops.
- Fitoverm. Biological insecticide designed to control most types of pests. It has an effect on sawflies and ticks. The drug can be combined with other types of insecticides, growth regulators. Processing during the flowering period is not recommended.
- tobacco dust. A popular biological group insecticide used to control and prevent infestation by harmful insects. It is applied to work with fruit, berry and flower crops. It is used as an infusion, decoction or for pollination of plants.
Biologically, insecticides have a slow effect, therefore, with a strong infection, it is recommended to use chemical preparations. The main advantage of such products is environmental friendliness and complete safety for humans and plants.
Acaricides
These are specialized preparations aimed at the prevention and destruction of plant mites.
Depending on the method of application, two groups of such funds are distinguished:
- Specialized. Destroy only ticks, practically do not affect other insects. The most famous means of this group are Apollo, Omite, Nissoran.
- Insectoacaricides. Chemicals designed to kill ticks and other insects. It is used more often than specialized drugs. famous brands- Actellik, Vertimek.
The use of acaricides is necessary when plants are heavily infested with mites, which are always difficult to get rid of. They can be used both for horticultural and agricultural crops, and for indoor potted plants.
General application rules
Before starting work, you need to carefully study the annotation for the drug, which always indicates the exact dosage and method of processing.
Depending on the type of insecticide, the following types of work are used:
- spraying green parts with an aqueous solution;
- fumigation - treatment of planting, harvest with steam or gas;
- dusting - scattering powder in dry form on plants;
- the introduction of an insecticide in the form of powder or granules into the soil during loosening, digging.
When working with water-soluble preparations, the dilution of the agent is carried out in stages. First, the insecticide must be dissolved in 1/3 of the required volume of water to obtain a concentrated mixture. Only then you need to add more liquid and mix everything thoroughly.
Processing should be carried out immediately after preparation, since then the drug begins to actively lose its properties, it becomes ineffective. When working with toxic insecticides, be sure to use products personal protection.
The best insecticides
The choice of a particular drug for treatment depends on many factors. These are climate features, plant species, a variety of harmful insects and the vegetation stage.
The most popular among gardeners are the following drugs:
- Spark. The active substance is cypermethrin. Produced in the form of powder for aqueous emulsion, tablets. The treatment is carried out by spraying. Fights many types of pests, especially effective against the Colorado potato beetle, aphids, moths and leafworms. The protective effect is preserved for a long time, it is economical to use.
- Commander. It is used against whiteflies, aphids and thrips. The insecticide has an effect on the Colorado potato beetle, some types of sawfly. The treatment is carried out by spraying. The active substance is imadocloprid, available in the form of water-soluble crystals.
- Medvetoks. The best drug against infection with a bear, ants and wireworm. The drug is applied to the soil at the rate of 3 g per 1 m 2, the duration of action is up to 20 days. The active substance is diazinon.
- Bankol. Enteric-contact insecticide, effective against most sucking and chewing harmful insects. Acts on nervous system pests, death occurs after 1-3 days from the moment of use. It has low toxicity.
Akarin (Agravertin). Biological insectoacrycide of intestinal-contact action. It is used to protect flower and vegetable crops. It has moderate toxicity, is dangerous for bees. Validity period - 4-16 hours depending on weather conditions.
In addition, from the above-described means for the prevention and control of pests in agriculture and horticulture, the following insecticides are often used: Aktellik, Fitoverm, tobacco dust and Aktara.
Precautionary measures
When working with any insecticide, simple precautions should be observed, since some agents are toxic to humans and pets.
Basic rules for working with chemicals:
- use personal protective equipment at any stage of work. These are goggles, gloves and a respirator;
- do not allow the product to come into contact with eyes, skin and mucous membranes. In case of contact, rinse the affected area thoroughly with plenty of water;
- after work, you need to wash your hands, as well as take a shower and wash clothes;
- storage of diluted insecticides is not allowed, the opened package with the drug must be carefully packed and put away in a place that is safe from children and animals.
If during operation the product enters the esophagus, eyes or respiratory tract, resulting in severe irritation and other symptoms, you should immediately consult a doctor.
Today, there are dozens of insecticides of varying degrees of activity. They are divided depending on the method and scope, the effect on insects. It is important to bear in mind that pests often develop addiction to the active ingredient, so the same drug cannot be used for a long time.
Insecticides are a subspecies of pesticides. These toxic substances are designed to fight harmful insects. They are able to destroy both mature individuals and their larvae. The spectrum of action of insecticides is quite wide. They are used to preserve foliage, fruits and stems on vegetable, grain, fruit and berry crops.
Before proceeding with the use of insecticides, it is necessary to know the exact concentration and dosage of the selected drug. Any insecticide preparation must have a complete package, easily readable labeling and instructions for use.
The labeling of the drug should indicate:
- . chemical composition,
- . main active ingredient
- . shelf life,
- . Hazard Class,
- . application regulations.
All of the above information can be located both on the package and on the leaflet-instructions for the use of the insecticide.
Fertilizer action
- . aphid,
- . thrips,
- . dog nose,
- . thunder leaflet,
- . apple tree,
- . scoops,
- . moth,
- . fleas,
- . ticks,
- . whitefly,
- . false shield,
- . scab,
- . Colorado beetle.
Types of insecticides
Ten years ago, only chemical-based preparations could be seen on the market, but due to the development of this industry, scientists began to develop insecticides on a plant, viral and bacterial basis. Modern drugs have become safe for the human body, which cannot be said about chemical insecticides.
Chemical preparations are based on organic compounds:
- . chlorine
- . phosphorus,
- . urea acid,
- . arsenic,
- . sulfur, etc.
Contact preparations allow you to act on a harmful insect only when the poison directly enters its body. In the event that it rains, the whole procedure may become useless, as the poison will be washed away.
A systemic insecticide affects both the pest and the plant itself. Toxic compounds enter vascular system plants, and therefore, become poisonous to insects. This poison is completely absorbed by the plant within a few hours, so it is no longer afraid of rain or watering.
The intestinal insecticide directly affects the pest, but it does not affect the environmental friendliness and safety of the treated plant.
The instructions for the insecticide should indicate the type of effect on insect pests. Therefore, the buyer can only choose on his own - which insecticides seem to him more effective and affordable ?!
The most popular drugs
The list of the most effective and popular drugs is presented as a result of the analysis of many customer reviews. It includes:
- . insecticide calypso,
- . Regent,
- . Boreas,
- . Prestige,
- . Bug.
- . drug 30.
Insecticide acts on insects by the intestinal contact method. This drug can be both applied to the soil and sprayed on plants. Effective against the Colorado potato beetle, scale insects, aphids. Validity 14-28 days. Toxic to bees.
Insecticide Regent effective against pests that live under the ground. A noticeable result was achieved in the fight against the wireworm. The mechanism of action is intestinal-contact. Highly toxic.
Insecticide represents a systemic effect on pests. It can be applied to most vegetables and fruits. Does not damage fruits. A fairly long period of protection, approximately 21-30 days.
Insecticide Bug affects pests by contact, systemic and intestinal. The protective ability is about 21 days. It can be applied to potatoes, grain crops, fruit trees.
Insecticide Preparation 30 created for fruit and berry trees, vines of grapes and berry bushes. It is recommended to process in early spring. Effective against a wide range of pests.
The price of insecticides varies depending on the main active ingredient, toxicity class and duration. On average, if you buy one capsule, the price can be from 25 rubles to 80-100 rubles per piece. Large volumes of such drugs are sold in canisters, so their cost starts from 600 rubles. It all depends on the type, volume and manufacturer.
Insecticides belong to a class of chemicals.
According to the principle of influence, they are divided into:
- contact-intestinal;
- systemic;
- fumigation.
Theoretically, they are best classified by chemical composition, since substances of the same class also have the same type of action mechanism.
Classification of insecticides
Phosphorus organic property
Organophosphorus insecticides are highly active, have a wide range of effects on organisms, have increased toxicity at the beginning of use, poor stability during operation, and rapid decomposition to the stage of compounds of already non-toxic properties on plants, as well as in soil and water. Organophosphorus preparations have a low consumption when calculating the area of the treated area.
When the preparations of this group decompose, the main part in this is taken by microorganisms.
Action on crops is from 10 to 20 days (open ground).
Organophosphorus-based garden insecticides are nerve-paralyzing poisons. Paralysis of the victim occurs, mostly ending in death.
The listed substances are contact-intestinal, some have a systemic nature of action, since they are distinguished by the ability to penetrate into root system, leaves.
Insecticide base: synthetic pyrethroids
Pyrethroids got their name from the similarity of their chemical formula with pyrethrins. natural origin(chamomile Pyrethrum), for their similar action. They appeared massively on the pesticide market after the 1970s. Until then, they were considered rather weak means and mostly ineffective. The formula was modified: pyrethroid compounds began to be produced, which are still leading in many positions today.
Are common acting properties pyrethroids:
- photostable;
- toxic at a selective level, given the metabolic degradation;
- the activity of each of the molecules is preserved with partial modification;
- the high activity of the insecticide remains, even taking into account the decrease in toxicity (for fish).
Pyrethroids are a type of insecticides, according to the principle of action, contact-intestinal, having high biological activity at the initial stage. To calculate the consumption rate, small proportions are taken as the basis.
Pyrethroids are effective against:
- Coleoptera and Lepidoptera insects;
- fleas, cockroaches and others.
neonicotinoids
Since ancient times, people have been able to prepare preparations with a nicotine base in the form of infusions from shag and tobacco. The first types of chemical nicotines were tested in the fight against insects even before the 1940s. They were highly toxic to insect species and also harmful to humans. There are known cases of receiving chemical shock by a person.
On Russian market insecticides neonicotinoids are represented by several drugs: imidacloprid (in the drug called "Condifor"), acetamiprid (in the drug "Mospilan"), thiamethoxam (drug "Aktara"), thiacloprid (drug "Calypso").
natural origin
So-called biopesticides have names milbemycins and avermectins. They have a neurotoxic effect.
Insecticides of other known chemical groups
Bensultap is a substance similar to a natural neurotoxin, it is obtained from outlandish marine worms Limbrineris brevicitra. 
This type of drug is effective on pests if they do not respond to others.
Diafenthiuron is a type of insectoacaricide used in protected ground. Effective against piercing-sucking insects and ticks. For example, on the greenhouse whitefly, on aphid species, on spider mites.
So, the drug "Pegasus" is able to inhibit the transmission of nerve impulses, which affects the cessation of feeding of insects, which then die. Repeated spraying is allowed with an interval of seven days (1-3 liters / 1 ha). This drug is considered harmless to humans.
Analysis of modern drugs
Diazinon Based Products
In different concentrations, this substance is found in insecticides with trade names: 
- Barguzin;
- Zemlin;
- Thunder;
- Medvetoks;
- fly-eater;
- Ant;
- Muracid;
- Ant-eater;
- Provotoks;
- Initiative.
These are drugs of non-systemic action, but a wide range of applications. Diazinon in the composition of these brands is practically insoluble in the aquatic environment, which allows you to fight pests that live on the soil surface. Effectively fight against wireworm and weevil, cabbage and onion flies, aphids, flea beetles and nibbling scoops.
In addition, preparations with diazinon have an acaricidal effect, that is, they act on spider mites. Diazinon insecticides have previously been used on houseplants, but due to its danger and ability to accumulate in the human body, it has been banned from household use and is now used only in the garden.
It should be remembered that diazinon contaminates the soil and The groundwater, its decay period can reach 18 days.Imidacloprid based products
The substance is part of drugs with the names:
- spark of gold;
- Commander;
- Confidor;
- Tanrek;
- Monsoon;
These are drugs of a systemic principle of action, and they spread through plant cells. Substances in the preparations dissolve well, are absorbed by plants, act through the root system. Drugs have proven themselves well in the fight against.
In addition, they act and fight against aphid species, parasitic insects, whiteflies and weevils, leafhoppers, but have no effect against spider mites and nematodes.
A drug from the same chemical group of the group (with another substance) called "Aktara" fights the scutellum, Colorado potato beetle and aphids. They are treated with roses and ornamental shrubs.
Imidacloprid is a highly toxic substance, extremely dangerous for all mammals, birds and fish, and humans. Due to its long decomposition period (up to 2 years), it is allowed for summer residents and gardeners to use on crops limited to the list.
Malathion Products
A substance with this name is part of the preparations: 
- Fufanon;
- Inta-CM;
- Phenaksin-plus.
These are drugs of non-systemic action and acaricides of a wide spectrum. Apply:
- on fruit against ticks and aphids, suckers and psyllids, apple moths;
- on berries against aphids and gooseberry yellow sawfly;
- in vineyards against mealybugs;
- on citrus fruits against whiteflies and mealybugs, red mites;
- on vegetable crops against aphids and mites, leaf-eating caterpillars.
That is why preparations with malathion are approved for use on any crops in gardens and home gardens.
Malathion preparations have been successfully used for more than 60 years in everyday life, in the medical field, in landscape design and park maintenance! So far, no signs of addiction of insects to malathion preparations have been identified.
A group of preparations based on biological microorganisms and fermentation products of soil bacteria.
This includes trademarks:
- Akarin;
- Fitoverm;
- Lepidocid;
- Bitoxibacillin;
- Iskra-Bio.
Despite the fact that this is a biological group of substances, they have an insecticidal, nematode effect. They fight scoops, leafworms, whites, ticks, Colorado potato beetles, moths, peach and melon aphids, thrips and other pests. 
A wide range of applications limits the condition under which drugs should be used: in warm time year, when the temperature outside is above 20 degrees Celsius. This condition is due to the fact that the biological product exerts its insecticidal effect through the intestinal system of pests, and they feed mainly when it is warm and there is enough moisture.
The drugs of this group are toxic, and you need to monitor the concentration, which can be dangerous for both animals and humans.
Some prices for the beginning of 2015:
- Thunder, Thunder-2 (from 15 rubles / 10 g);
- Bison (from 30 rubles / 1 ml);
- Anteater (from 15 rubles / 1 ml);
- Muracid (from 15 rubles / 1 ml);
- Fly-eater (from 20 rubles / 10 g);
- Initiation (from 20 rubles / 30 g);
- Provotox (from 45 rubles / 120 g);
- Prophylactin (from 510 rubles / 500 ml);
- Slug-eater (from 30 rubles / 30 ml);
- Senpai (20 rubles / 5 ml).
Overview of insecticides
Almost every gardener knows that in order to grow a rich harvest, it is important not only to provide plants with favorable conditions cultivation, but also to protect plants from pests. It is not only gardeners who face the problem of pests. Houseplants are also often in the affected area. How to choose the right way to deal with insect pests read in the articles " " And " ". In this article I will review popular insecticides, most often recommended on garden marketplaces and flower growers' forums.
An overview of insecticides.
In this review, I will not dwell on the instructions for breeding chemical preparations. This information can always be found on the packaging of drugs. I will dwell on the features of their impact and side effects application, placing drugs as their strength increases.
Fitoverm, Akarin (Agrovertin).
Fitoverm
Smell-sparing insecticides: Fitoverm, Akarin (Agrovertin). Produced on the basis of microbiological synthesis. Effective against ticks, whiteflies, , thrips and other insects, as well as their larvae.
There is almost no smell that can cause allergies in children and households. At Akkarin (Agrovertin), it will be barely noticeable after less than an hour of airing the room.
The preparations are contact-intestinal, they are not absorbed into the fruits and plants. Fruit can be harvested 2 days after the last treatment.
Fitoverm, Akarin (Agrovertin) - practically do not cause addiction in harmful insects.
For effective exposure, the preparations should be sprayed directly on the skin of the pests, and the leaves of the plant should be evenly and abundantly moistened. It is necessary that in the first 8-10 hours after treatment, the plants do not fall under the influence of natural precipitation. Temporarily do not spray treated indoor flowers, but carry out only in the basal way, and not by spraying.
Akarin (Agrovertin) is especially effective in high temperatures, more than 18°С.
Fitoverm retains its protective functions within 7-20 days, Akarin is slightly less, but much depends on the environment.
Guaranteed shelf life in original sealed packaging is 2 years. Storage of diluted preparations is not allowed. The prepared solution must be used within an hour.
When sprayed, they do not leave stains. Can be used during the flowering period and at home.
Moderately dangerous for bees and inhabitants of reservoirs.
Flaws. In connection with short term the action of the active substance is not effective against pest eggs. Many flower growers note that they are "weak", not effective. You need to understand that this is a “payment” for a gentle effect on flowers, the possibility of using it when fruits ripen and the absence of a pungent odor. Recommend for prevention indoor plants.
Actellik.
Actellik
Actellik is a broad-spectrum insecticide and acaricide based on organophosphorus compounds. The period of action of the active substance is 7-14 days.
It is effective not only as a means of controlling insect pests, but also affects ticks and barn pests. That is why many flower growers often opt for it. Even if the plant is this moment struck by harmful insects, simultaneous prevention against ticks will not hurt.
Among the shortcomings, a strong smell can be noted. Therefore, it is desirable to carry out the processing of home flowers on fresh air where you can leave the plant until completely dry and aired. As an option, spray indoor flowers on weekends if you are going to leave for a few days.
Very toxic to aquatic life. Therefore, do not process indoor plants in rooms with an aquarium and in cottages near water bodies.
Dichlorvos, Karbofos.
dichlorvos
They belong to the same group of drugs as Actellik. Dichlorvos and Karbofos have been known, perhaps, since grandmother's times and until recently, one of the most common and used drugs.
Dichlorvos is available in the form of aerosols, karbofos in various commercial forms.
Dichlorvos is more often used to control insects and mites in everyday life, and karbofos in agriculture. With its help, they not only fight against harmful insects and mites, but also carry out disinfection of warehouses to destroy stock pests.
They are highly toxic not only to insects, but also to humans. They have a strong, poorly weathered smell. As a result of long-term use, entire groups of pests have developed resistance to these chemicals.
Dichlorvos preparations, produced under the brands "Neo" (the effectiveness of the product is 15 days) and "Varan" (the effectiveness of the product is 20 days), are devoid of a pungent odor and are even flavored with mint and lemon. But we should not forget that the smell performs additional warning functions when spraying these toxic agents. Acute poisoning with dichlorvos and karbofos is not uncommon.
Aktara.
Aktara is a modern, well-established, moderately persistent, broad-spectrum systemic insecticide. A very popular chemical protection against aphids, whiteflies, thrips, , false scale insects and their larvae. Does not work on ticks.
Virtually odorless.
It is applied both by spraying on the surface of the plant, and by watering pre-moistened soil in the root zone. When dealing with pests of indoor plants, I advise you to combine spraying with watering. It is absorbed and acts on pests through plant sap, therefore it is not recommended for processing food and fruit crops. In case of severe damage to such crops by a pest, it is allowed to use Aktara before flowering and after harvesting the fruits.
The chemical agent is active on the leaf surface for 2-3 weeks, with soil application up to 8 weeks. The long term of activity of the active substance allows you to be sure that a new generation of harmful insects that have emerged from eggs is guaranteed to fall under the action of the drug. There is no need for additional processing.
Spraying the working solution of Aktara must be carried out using personal protective equipment. The drug is very toxic to bees, toxic to fish, birds and animals.
Shelf life in the original packaging is 4 years. Storage of the working solution is not allowed.
After treatment, it is necessary to carefully dispose of the remains of the drug, containers and water, which was used to wash the sprayer and auxiliary equipment.
I advise you to use Aktara only in case of severe damage to the plant by a pest and on early dates vegetation. Due to the strong toxicity of the drug, the flower itself often dies along with harmful insects, especially for indoor plants that do not have high natural immunity.
Nurell-D, Bi-58, Bi-58 New.
Nurell_D, Bi-58
In the garden, during the beginning of the growing season of plants, in the event of the appearance of pests and basic treatments, I advise you to use Nurell-D or Bi-58. They provide effective protection from apple, plum, pear codling moth, leafworm (not all types), pipeworm, cherry fly, plum pachyderm, aphids, spider mites of the eastern codling moth and fruit sawflies. They are also distinguished by high efficiency of action on ticks resistant to organophosphorus compounds.
Nurell-D, Bi-58, Bi-58 New is quickly absorbed by plants, so frequent spring rains will not reduce the effectiveness of the product. The preparations have long half-lives of the active active substance, and do not depend on temperature regimes.
When applying these chemicals need to pay Special attention so that children and pets do not penetrate the treated flowers.
Preparations are very dangerous for inhabitants of reservoirs and bees. Therefore, the treatment of garden plants must be carried out before the flowering period so that the active substance does not get into the nectar and pollen.
When spraying drugs, the use of personal protective equipment is mandatory.
Spraying can be carried out before and after flowering, a month before harvesting. 1-2 treatments of affected plants are enough.
