Abstract

The invention discloses a pesticide composition containing propylene glycol alginate and diafenthiuron. The weight ratio of the propylene glycol alginate to the diafenthiuron is 1: 40 to 40:1, and preferably 1: 10 to 10: 1. The composition has an excellent effect for preventing and controlling tea lesser leafhopper, can reduce the pesticide consumption and can decrease the pesticide application cost.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a pesticide composition containing propylene glycol alginate and diafenthiuron. Background technique [0002] Propylene glycol alginate is a commonly used food additive. It is harmless to humans, animals and the environment, and it can also be used as a biological insecticide with a physical mechanism of action. The mode of action is contact killing. With its unique viscosity and physical Contact killing, quickly closes and blocks the stomata of pests for respiratory metabolism, blocks the metabolism and circulation channels of pests, and suffocates them to death. It can effectively control whitefly, red spider, pear psyllid, tea leafhopper, aphids and rice Pests that are difficult to control in agriculture such as planthoppers. [0003] Diafenthiuron is a new type of thiourea high-efficiency insecticide and acaricide, which has contact killing, stomach poisonin...
