Embodiment 13～24

[0035] Embodiment 13~24 water dispersible granules

[0036] 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 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

A disclosed pyriminostrobin-containing insecticidal composition containing an active component A and an active component B with a weight ratio of 1:70-70:1, the active component A is pyriminostrobin, and the active component B is any one compound selected from pyridaben, propargite, avermectin and tebufenpyrad. The composition has synergic effect on multiple harmful mites harmful to agriculture production, the pesticide usage amount is reduced, the pesticide residual quantity on crops is reduced, environmental pollution is mitigated, and the composition is safe to people and livestock, good in environment compatibility and insusceptible to arousing 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 pyrimidan to crop pests. 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] Pyridaben, propargite, abamectin, and tebufenfen are all commonly used insecticides, which are widely used to prevent and control insect pests on crops, and the control effect is good. [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 whether a certain compound is synergistic, additive or antagonistic. In ...
