example 17～32

[0046]Example 17~32 water dispersible granules

[0047] Propylene glycol alginate, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are crushed together by air flow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. 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 a high-efficient insecticide composition containing propylene glycol alginate. The high-efficient insecticide composition comprises an active component A and an active component B. The active component A is propylene glycol alginate; the active component B is one compound optionally selected from flonicamid, cyantraniliprole, tolfenpyrad, sulfoxaflor, flubendiamide, and chlorantraniliprole; and the weight ratio of the active component A to the active component B is 1:80-60:1. The high-efficient insecticide composition possesses obvious synergistic effect on a plurality of insects which are capable of causing harm to agricultural production; is capable of reducing insecticide dosage, insecticide residue on crops, and environmental pollution; is safe for people and livestock; and possesses excellent environmental compatibility. In addition, drug resistance of insects is difficult to be caused by the high-efficient insecticide composition containing propylene glycol alginate.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency insecticidal composition containing propylene glycol alginate on crop pests. Background technique [0002] Propylene glycol alginate molecular formula: (C 9 h 14 o 7 ) n , which is an emulsified suspension prepared from seaweed extract through an emulsification process, and has contact killing activity on insects. [0003] Flunicamid, cyantraniliprole, tolfenpyrad, sulfonicafran, flubendiamide, and chlorantraniliprole are all commonly used insecticides and are widely used in crop pests. [0004] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The compounding of ingredients from different varieties is a very common way to control resistant pests. Different ingredients are compounded, and according to the actual application effect, it is judged whethe...
