Do you really know about pesticides?

What is the mechanism of action of pesticides: Gastrotoxicity, Triggering, Endosorption and Fumigation?

Insecticides can enter the body of pests in an important way to act on pests in a way and method generally speaking, divided into gastric toxicity, poisoning, poisoning, endosorption and fumigation four major types of therapeutic effects:

1. Gastrotoxicity, refers to the pesticide sprayed on crops, or mixed into seeds or baits, when the pests eat,RAMBO insect killer supplier the pesticide with the food into the digestive tract of the pests, resulting in poisoning.

2. Touch kill refers to the pesticide sprayed on the surface of the insect or its habitat or plant, through the epidermis or sensory organs of the insect into the insect's body, or even through the valve into the insect's body, resulting in the death of the insect poisoning.

3. Internal absorption refers to the absorption of pesticides by the roots, stems, leaves and other tissues of the plant, thus killing the feeding sap of the pests.

4. Fumigation refers to the volatilization of pesticides to form a gas that enters the respiratory system through the insect's valve and then spreads to all parts of the insect's body, ultimately leading to the death of the pest.

What is selective toxicity of pesticides?

Selective toxicity of a pesticide means that the pesticide is toxic to some pests but not to others, or to one tissue or organ of the pest but not to others.

What are the methods of application of pesticides?

There are many ways to apply pesticides, such as spraying, dusting, sprinkling, seeding, spraying, dipping,VITFE insect killer manufacturer fumigating and so on. Depending on the type of pests, there are different methods of applying pesticides. For example, for underground pest control, you can choose seeding, baiting, soil and other methods.

How to prevent and control pests from developing drug resistance?

You can prevent and delay the emergence of pest resistance by studying the following main ways at the same time:

(1) Fully utilize integrated control techniques. Under the guidance of the plant protection policy of "prevention and control as the mainstay, integrated management", fully utilize agricultural, biological, physical and chemical methods, and even include all artificial ecological measures for pest control.

(2) Apply medicines regularly in alternating doses and do not increase the dosage arbitrarily.

(3) Mixing of two or more drugs with different mechanisms and modes of action.

(4) Reduce the dosage of drugs, reduce the frequency of drug administration, and lengthen the interval of drug administration.

(5) Use more selective pesticides and less pesticides with long residual periods.

(6) Use synergists when applying pesticides.

(7) Choose to apply pesticides during the sensitive period of the pest.

What is the best time for pest control?

Larvae (before the age of 3) have relatively thin body walls, Chinese SLEEP COOL Insecticide spray small size, small food intake, light damage, small range of activities, weak resistance to drugs, while the older larvae increase in body fat. Experiments show that the higher the fat content of the pest, the stronger the resistance. This shows that the timely application of drugs to young pests is the key to improving the effectiveness of control.
