Insecticide treatment

All plant protection chemicals are called pesticides. This group includes preparations of various actions: Insecticides - preparations for combating pests of indoor plants. Insecticides are not effective against disease. Acaricides - means of combating herbivorous mites. Fungicides - means of combating fungal infections and fungi. Bactericides are means of combating bacterial diseases.

Often, ordinary indoor plant lovers do not use such an accurate taxonomy and appeal only with two concepts - insecticides (including nematicides and acaricides) and fungicides (including bactericides). This is explained by the fact that most drugs usually have a fairly wide spectrum of action, showing other, less pronounced properties.

Insecticide action

Insecticides can have different ways of acting on pests:

Contact insecticides - enter the pest's body through the integument of the body. Treatment with such preparations requires thorough wetting of surfaces or immersion of the entire aerial part in a solution of the preparation.

Intestinal insecticides - enter the pest's body when feeding on plant sap. It also requires careful processing of plants.

Systemic insecticides - able to penetrate deep into plant tissues, and spread into them. Such preparations are especially effective against pests and larvae living in plant tissues (nematodes, mite larvae, etc.), systemic preparations are used for irrigating plants, the active substance is absorbed with moisture from the soil.

Insecticides of fumigate action - entering the respiratory organs of pests and through the integument of the body.

There are also drugs of mixed action, for example, intestinal contact.

The strength of the action of various drugs depends not only on the dose or on the shelf life, but also on the drug itself, some of them have a stronger effect, others less. Typically, the stronger the drug, the lower the degree of toxicity is indicated. For example, actellic is a very strong drug against pests of indoor plants, even one spraying is enough to heal a very badly damaged plant, while actellic has II hazard class - i.e. dangerous to humans, and you need to work with him very carefully. But when spraying with insecticides with IV hazard class, more than one treatment may be needed.

In case of mass infestation with pests, you can treat all contacting surfaces (glass windows, frames, window sills, tiles, etc.) if possible. Then these treated surfaces are thoroughly washed from the insecticide with running water and soap.

Pesticide form

The form of chemical preparations for the destruction of pests can be different: solution, dry wetting powder, emulsion, spray. The most convenient form for processing indoor plants is solutions in vials or ampoules. Usually the capacity of ampoules or vials is 2-5 ml, which is usually enough for spraying 50-100 plants. Wetting powder and sprays are less preferred. Powders are more difficult to dilute by eye, some of the preparations are not soluble in water (for example, sulfur), they can remain on the leaves in the form of dust deposits. Sprays better moisten surfaces and secluded places on plants, but due to their finely dispersed form they easily penetrate the human respiratory tract, causing irritation.

In any case, most of the pesticides (insecticides, acaricides, fungicides) that are banned in many European countries for use in living quarters, we Russians, without hesitation, use in our apartments to treat our favorite flowers.

In fact, many drugs are highly toxic and require mandatory safety measures, drugs with hazard class 2 and 3 are desirable (but who will forbid you!) Not to use at home. In April 1992, a description of malathion vapor poisoning Malathion appeared in the press - the active ingredient of some insecticides and acaricides, in this case, malathion was used. So, a hundred meters from the primary school, plants were sprayed with a hand sprayer (according to the illuminated data, 22 ml of malathion were used), after a while the students began an attack of hysteria, as a result, 296 people were hospitalized, with nervous disorders caused by the smell of malathion (College of Agriculture, University of Arizona, Tucson).

Insecticide and fungicide treatment at home

If you have the opportunity to process your flowers outdoors, in the fresh air, take advantage of it. In this case, all safety measures boil down to the fact that you need to work with gloves and an apron, do not use food utensils, do not drink, smoke or eat during work, do not scratch your nose or ear with dirty hands. But if there is no opportunity to take out and spray plants on the street or on an open balcony, many do not see a way out of how to process the plant right in the apartment. In this case, security measures should be much more serious.

First, spray the plants in an area that has better ventilation and is easier to ventilate. Someone does it in the bathroom, where there is a good extractor hood, someone else - in a room where you can open a window.

Two to five plants are easier to process in the bathroom, if there are many more, then it is easier to work in the room by spreading a large piece of greenhouse film on the floor. Secondly, put on a work gown before work, you can use a polyethylene raincoat (disposable), a shower cap, transparent construction glasses, a respirator and rubber gloves.

After finishing work, hands, face and all used equipment should be washed with soap and water. Store insecticides in a dry place, out of the reach of children and animals, keep away from fire. Storage of working solution is not allowed!

Many chemicals have a high hazard class and are highly toxic to humans. For example, the popular Sunmite acaricide (the active ingredient is pyridaben) has a hazard class 2, although buyers are often deceived - the label says hazard class 3, in fact, it is only for bees! In terms of oral and dermal toxicity, pyridaben is moderately dangerous for humans, and dangerous for inhalation. Symptoms of poisoning: depression of the central nervous system, decreased motor activity, paralysis, staggering gait, nasal discharge, increased breathing rate, ataxia, weakness, decreased body temperature. This is serious enough!

Among other things, the carcinogenic properties of pesticides have not been studied at all and have not been illuminated in the literature, this does not mean that they do not exist.

Take protective measures, exclude children and pets from the treated apartment. After the leaves have dried, be sure to ventilate the room. In order not to "freeze" the flowers in the path of the air flow, put a screen (for example, a sheet of plywood), do not allow the temperature to drop below 12-13 ° C. Many drugs lose their toxicity in a few hours after spraying and become harmless.

If there is an aquarium in the room, then it is tightly closed and only opened when the treated plants are dry.

In order not to suffer from headaches, nausea and not endanger the health of yourself and your family, spray in the morning, isolate the treated plants for several hours, i.e. leave them behind a closed door in a room with an open window.

First aid in case of poisoning: if the drug gets on the skin, wash it off with soap and water; in case of contact with eyes, rinse abundantly with running water; if it enters the digestive tract, drink 3-4 glasses of water, induce vomiting, take a few tablets of activated carbon, seek medical help.
