example 17～32
[0047] Example 17~32 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 present invention discloses a pesticide composition, which contains an active component A and an active component B, wherein the active component A is selected from propylene glycol alginate, the active component B is any one compound selected from spirotetramat, chlorfenapyr, lufenuron, pyriproxyfen, metaflumizone and pyridalyl, and a weight ratio of the active component A to the active component B is 1:80-40:1. The composition provides high activities for a plurality of pests of a plurality of crops, and has characteristics of significant synergistic effect, pest killing spectrum expanding, low use amount, rainfall erosion resistance, and significant synergy.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a 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] Spirotetramat chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5]- Dec-3-en-2-one, molecular formula: C 21 h 27 NO 5 . Spirotetramat has unique action characteristics and is a rare existing insecticide with two-way systemic conductivity. It has a wide insecticidal spectrum and a long duration of action, which can provide effective control for up to 8 weeks. It works by interfering with lipid biosynthesis in insects leading to larval death and reduced adult reproductive capacity. Due to its unique mechanism of action, it can effectively control pests resist...
