Insecticide composite containing dinotefuran, preparation formulations and preparation method thereof

Abstract

The invention discloses an insecticide composite containing dinotefuran, preparation formulations and a preparation method thereof, belonging to the technical field of chemical prevention and controlling of pests. In the insecticide composite, an effective ingredient A is dinotefuran, and an effective ingredient B is one of Silafluofen or Ethofenprox, wherein the weight ratio of the ingredients A and B is (1:20)-(20:1). In addition to the effective ingredients, the insecticide composite also contains accessory ingredient and filler; the effective ingredients A and B account for 15-50% of the total weight of the insecticide; the accessory ingredient accounts for 20-30% of the total weight of the insecticide; and the balance is filler. The insecticide composite can be prepared into wettable powder, suspension agent and the like. The insecticide composite has good preventing and curing effect on rice planthoppers, aphids, vegetable Bemisia tabaci Gennadius and the like. Compared with the common chemical agents for preventing and controlling rice planthoppers, the insecticide composite is characterized in that dosage is reduced, environmental pollution and pesticide residue are lowered, resistance of rice planthoppers against single-component insecticides can be delayed, and the insecticide composite has the advantages of long efficacy acting period. Compared with the cost of single-component chemical agents, the cost of the insecticide composite is lowered.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control and relates to an insecticide composition containing dinotefuran. Background technique [0002] Rice planthopper (BPH, SBPH, SBPH) is a kind of rice pest with strong migratory ability (except SBPH) and extremely fast reproduction speed. It damages rice and causes the base of rice clumps to be dark brown and the heading is abnormal. , the thousand-grain weight is reduced, and in severe cases, the whole plant will wither, resulting in a substantial reduction in rice production, and it can also spread viruses to cause stripe leaf blight and black-streaked dwarf disease. It is one of the main pests of rice. For a long time, the control of rice planthoppers has mainly relied on imidacloprid, buprofezin, organophosphorus and their compounding agents. The use of highly toxic organophosphorus pesticides has been banned. Due to long-term single and continuous use, brown planthoppers and brown...

AI Technical Summary

Problems solved by technology

The cost of dinotefuran, etofenprox or flufluthrin to effectively control rice planthoppers is relatively high, and the cost of controlling rice planthoppers alone by the two is relatively high, and drug resistance is likely to occur, and insecticides with different mechanisms are used for compounding , is the main method of controlling resistant pests
