However, due to the extensive use of pyrethroid pesticides, they can also cause resistance to various pests. Therefore, when using pyrethroid pesticides, the following points should be achieved: first, to prevent the formation of pyrethroid fever, and strictly control the application frequency and dose. Repeated use of pyrethroid pesticides can create favorable conditions for pests to develop resistance. Generally, pyrethroid pesticides can only be used two or three times during the growing season or within a year to kill insects, and the dosage for each application should be low according to the instructions for use.
The second is to use it in reasonable rotation with other pesticides. The rotation of pyrethroid pesticides with other pesticides can help reduce the number of times they are used and prevent pests from developing resistance. For example, it can be combined with the insecticides of the sandworm virus line, such as Xiaoshuang and Nongmonte; And organophosphorus pesticides such as monocrotophos, phoxim, omethoate, fenitrothion, quinthion, and isocarbophos; It is used in rotation with pesticides such as methomyl and leafhopper powder among carbamate pesticides.
Third, it is mixed with other pesticides. The mechanism of pyrethroid pesticides is similar to that of DDT, both of which interfere with nerve conduction mechanisms and cause pests to die. Mixing pesticides with different insecticidal mechanisms can greatly delay the emergence and development of pest resistance. The promoted and used products include fenvalerate (DDZ+monocrotophos), chrysanthemum horse oil (DDZ+malathion), oxypermethrin (DDZ+omethoate), mesalazine (DDZ+methamidophos), bromoctyl emulsifiable concentrates (DDZ+phoxim), and DDZ+mirabilin. Mixed use has good effects.
The fourth is to prevent poisoning. Pyrethroid pesticides are highly toxic to fish, bees, and natural enemies. Therefore, during use, attention should be paid to: (1) Do not allow the medicinal liquid to flow into rivers and ponds; (2) Be careful not to use it in the bee feeding area; (3) Drug users should pay attention to protection, wear masks, wear long-sleeved clothes and pants, etc; (4) Do not spray in high temperature and scorching sun, do not spray in the wind, etc.
