Embodiment 13~24

[0036] Embodiment 13~24 water dispersible granules

[0037] Pyrimimethan, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain 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 present invention discloses a pyriminostrobin-containing acaricidal composition, which is an acaricidal composition containing an active component A and an active component B, wherein the active component A is selected from pyriminostrobin, the active component B is any one compound selected from etoxazole, fluacrypyrim, acequinocyl and cyflumetofen, and a weight ratio of the active component A to the active component B is 1:70-70:1. The composition provides synergy effects for a plurality of harmful mites harmful for agricultural production, and has characteristics of pesticide consumption reduction, reduction of residual pesticide on crops, environmental pollution reduction, safety to human and animals, good environment compatibility, and harmful mite drug resistance generation resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an acaricidal composition containing pyrimidazan on crop pest mites. Background technique [0002] Pyrimidan: It is used to prevent and control Panonychus citrus, and the product shows good quick-acting and long-lasting effects under field test measurement. [0003] However, in the actual process of agricultural production, the most likely problem in the control of pest mites is the generation of pesticide resistance of pest mites. The compounding of ingredients from different species is a very common way to control resistant pest mites. 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 with very obvious syne...
