[0047]

[0048] Example 13 ~ 24 water dispersible granules

[0049]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 the fluidized bed granulation dryer for granulation and drying, see Table 3 and 4 for details.

Abstract

A disclosed insecticidal composition containing propylene glycol alginate is an insecticidal composition containing an active component A and an active component B, wherein the active component A is propylene glycol alginate, the component B is any one selected from imidacloprid, acetamiprid, dicyclanil and ethiprole, and the weight ratio of the active component A to the active component B is 1:80-60:1. The insecticidal composition has synergic effect on multiple insects harmful to agriculture production, helps to reduce pesticide use amount, reduce pesticide residue on crops and mitigate environmental pollution, and is safe to people and livestock, good in environment compatibility and insusceptible to arousing the drug resistance in the insects.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an 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 made from seaweed extract through an emulsification process, has contact killing activity on insects. [0003] 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 whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effect of pesticides is an additive effect, and there are few real synergistic effects, especially those wit...
