Any agrochemical compound contains one or more active substances, the properties of which determine the desired effect of the drug. Substances can be fertilizers, growth stimulants, suppress the development of weeds, and eliminate harmful insects. Today we will talk about the properties of thiamethoxam and drugs based on it.
Physical and chemical properties
This organic compound - [5 methyl-3-(2-chlorothiazol 5-ylmethyl) 1,3,5-oxadiazinan 4-ylidene-N-nitroamine] - belongs to the chemical class of neonicotinoids.It is a cream-colored, odorless crystalline powder. It has a molecular weight of 291.7, melts at a temperature of 139.1 ° C, dissolves in water - 4.1 grams / liter (at a temperature of +25 ° C).
Used in agriculture in the form of a single or multi-component pesticide. It belongs to systemic and contact insecticides and has translaminar ability. It is used for spraying plants, can be applied at the root, and is used as a seed protectant.
Insecticides are compounds that can cause the death of adult insects and larvae, protecting plants from pests. The translaminar effect refers to the ability of a pesticide to penetrate the underground and above-ground parts of the plant, making it poisonous to insects. Leaves become dangerous for pests 20-22 hours after spraying. In this case, the drug does not penetrate into the fruit.
Preparations based on thiamethoxam are used to treat cereal crops, vegetable crops, fruit trees and flowers. It is used on vast agricultural lands and in private farms. Used for treating indoor and greenhouse plants.
Effect on harmful organisms
Contact with the insecticide or eating the treated parts of the plant causes paralysis in insects, since thiamethoxam affects the nervous system of the pest. Failure of life-support systems leads to the death of insects. The drugs do not cause resistance and are not dangerous for plants. Agrochemicals based on thiamethoxane are effective against:
- various types of aphids;
- thrips;
- scale insects;
- Colorado potato beetle;
- wireworm;
- bread ground beetles.
Another number of insect pests will disappear from the area treated with substances containing thiamethoxane.
Pesticides containing thiamethoxam
Such products are available in various preparative forms: water-soluble granules, concentrated suspension, powder, tablets. All insecticides are produced in waterproof packaging, indicating the name of the drug, manufacturer, purpose, and rules of use.
The most well-known drug to gardeners containing thiamethoxam is “Aktara”, these are water-soluble granules. Analogues of the active substance are also:
- "Shell" KS;
- "Doctor" TB;
- "Insector" KS;
- "Tiara" KS;
- "Cruiser" KS.
The drugs should be used strictly according to the manufacturer's instructions, without exceeding the recommended concentration of the working solution. They can be used in sunny weather. Having penetrated the xylem of the plant and spread inside, the products protect the crop for a long time, regardless of weather conditions.
Instructions for use of the drug
Products are diluted with water in accordance with the manufacturer's recommendations. Seed protectants based on thiamethoxam and preparations for watering and spraying plants during various periods of the growing season are produced.
Safety precautions when using the drug
The products have a hazard class 3 for humans and a hazard class 2 for bees. This means that they are not too toxic for people, but bees may die. Therefore, beekeepers should be warned about the proposed treatment of plants. Toxicity persists for 5-7 days.
When working in a personal area, wear long-sleeved clothing made of thick fabric. It should be fastened with all the buttons. The hair is covered with a headscarf or cap. While carrying out work, smoking and eating are prohibited. After spraying, you need to wash exposed areas of the body and change clothes. If ingested, you must empty your stomach and consult a doctor, taking the packaging or instructions for the drug with you.
Compatibility with other substances
The products are compatible with many other pesticides, fertilizers, growth stimulants and are suitable for making tank mixtures. You should first read the manufacturer's recommendations and check the substances being mixed for compatibility.
