(1) Drug resistance is related to pests and their living habits. The life history is short, and the number of breeding algebras per year is high. The pests that have many opportunities to contact with the pharmacy, such as mites, shells, mites, mosquitoes, etc., are the most susceptible to resistant populations;
(2) A pest is resistant to a pesticide and is often resistant to other pesticides of the same type; such interactions are less likely to occur between drugs with different insecticidal mechanisms;
(3) The same pesticide is used continuously for a large number of times or a high concentration of treatment, and resistance is formed rapidly, and vice versa.
Knowing this, farmers can prevent or delay the rise of pest resistance through rational use of drugs. To this end, we advocate the adoption of comprehensive prevention and control policies including breeding, promotion of resistant varieties, improvement of cultivation techniques, and development of various technologies such as biology and physics to minimize the number and dose of chemical control.
The second is to choose pesticides with different mechanisms of action, mixed use and inlaid application.
Finally, improve the application of pesticides, such as symptomatic medication, timely spraying, selection of high-efficiency equipment, spraying in place, etc., to maximize the killing effect.
Why is the use of pesticides less effective?
I often hear from farmers saying that the effect is very good when I start using insecticides, but as the dosage is increasing and the range of use is expanding, the insecticidal effect is getting worse and worse. Why? This is actually because the pests develop resistance, and each time the insecticide is used, the relatively resistant individual will be left behind. That is to say, by breeding, the level of resistance of the pest population is more or less improved, as shown below. What time is it:
