example 7～12

[0047] Example 7~12 water dispersible granules

[0048] Propylene glycol alginate, active ingredient B, dispersant, wetting agent, disintegrating agent, and filler are crushed together by airflow 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 is obtained by 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 pesticide composition containing 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 spinosad and ethyl spinosad; and the weight ratio of the active component A to the active component B is 1:80-60:1. The high-efficient pesticide composition is capable of controlling a plurality of insects, possesses obvious synergistic effect, and is capable of widening insecticidal spectrum, and reducing pesticide dosage, pesticide residue on crops, and environment pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a high-efficiency pesticide composition on crop pests. technical background [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] Spinosad has rapid contact and stomach poisoning effects on pests, has a strong penetration effect on leaves, can kill pests under the epidermis, has a long residual period, and has a certain effect on some pests. Ovicidal effect, no systemic effect. [0004] Spinetoram is a new member of the spinosyn class of insecticides. It is obtained by chemically modifying the natural product spinosyns. It is a brand new and unique active ingredient in the spinosyn class of insecticides. . [0005] In the actual process of agricultural production, the most likely problem in pest...
