Compound insecticide

Abstract

The invention discloses a compound insecticide; the active ingredient consists of abamectin and inhibitory food hydrazine, wherein the abamectin is 0.4g.a.i to 20g.a.i and the inhibitory food hydrazine is 1.0g.a.i to 60g.a.i. by weight; in the effective content of the compound insecticide, the abamectin takes up 1.6% to 98.0% of the effective ingredient of the compound insecticide, and the inhibitory food hydrazine takes up 1.0% to 98.0% of the the effective ingredient of the compound insecticide. The compound insecticide provided by the invention has a remarkable synergistic effect relatively to the independent abamectin or inhibitory food hydrazine, and is capable of preventing and treating insect pests such as rice longitudinal leaf rice or borer (including sesamia inferens, chilo suppressalis and tryporyza incertulas); and the compound insecticide has advantages of high efficiency, persistent effect, low toxicity, low cost, environmental protection, and very wide application prospect.

Description

technical field

[0001] The invention relates to a compound insecticide whose active ingredient is a combination of abamectin and hydrazine, and belongs to the field of pesticides. Background technique

[0002] Rice is the food crop with the largest planting area in China. Its pests and diseases have the highest frequency of occurrence and the most serious damage. In particular, the occurrence of rice leaf rollers spreads all over the rice areas of my country, seriously threatening the safety of food production in my country. At present, the control of rice leaf roller mainly relies on chemical agents, mainly organic phosphorus such as profenofos and chlorpyrifos, and biological agents such as abamectin and emamectin. These agents have good quick-acting effects on young larvae. The cost is low, but the persistent effect is poor (about 5 days), and the control effect on larvae above the 2nd instar is very poor; the monosultap and diinsultap have slightly better long-lasting ef...
