Embodiment 11～20

[0046] Embodiment 11~20 water dispersible granules

[0047]Penflumizone, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. are crushed together by air flow to obtain the required particle size, and then other additives such as binder are added to obtain the granulation material. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

Abstract

The invention discloses an insecticidal composition containing Wufuchongzong and carbamate, wherein Wufuchongzong is a novel pesticide. The insecticidal composition comprises an active component A and an active component B, the active component A is Wufuchongzong, the active component is one of carbaryl, isoprocarb, and triazamate, and the weight ratio of the active component A to the active component B is 1:80 to 60:1. The provided composition has a synergetic effect on a plurality of insects that damage the agricultural production; thus the using amount of pesticide is reduced, the residual pesticide on crops is also reduced, the environmental pollution is relieved, the composition is safe to human and livestock, the environmental compatibility is good, and insects cannot generate drug resistance easily.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing penfluflumizone and carbamates on crop pests. Background technique [0002] Penfluflumizone is a new type of insecticide, which can be used to control pests on crops, is safe to the environment and crops, and is resistant to rain. [0003] Carbaryl chemical name: 1-naphthyl-N-methylcarbamate, molecular formula: C 12 h 11 NO 2 . Carbaryl has a broad spectrum, inhibits acetylcholinesterase in pests, and has good control effect on leafhoppers, planthoppers and some pests with chewing mouthparts that are difficult to control, such as red bollworm. , parathion and other pests that have developed resistance have a good control effect. The poisoning effect of this drug is slow, and it can be mixed with some organophosphorus pesticides, and the control effect is poor at low temperature. . [0004] Isoprocarb (isoprocarb) c...
