Abstract

The invention discloses a pesticide composition and application, which consists of methylamino avermectin benzoate and fluorine cyanogen at with optimum weight rate at 1: 4.

Description

technical field [0001] The invention relates to a pesticide, in particular to a pesticide composition containing emamectin benzoate and fipronil and application thereof. Background technique [0002] With the improvement of human requirements on food and environment, the use of pesticides on vegetables that people depend on has also attracted much attention. First of all, the use of highly toxic organophosphorus insecticides on vegetables has caused serious pesticide residue problems, so the reduction of highly toxic organophosphorus insecticides has become a major issue in my country's pesticide industry. The elimination of organophosphorus pesticides has freed up There is a huge market space for pesticides, and it is hoped that there will be new varieties of pesticides that are efficient, safe, and environmentally friendly. Secondly, the long-term use of pesticides makes pests resistant to pesticides, and the requirements for control agents are getting higher and higher. T...
