Composite pesticide of one class preventing and control rice pests

Abstract

The invention relates to a high-effect and low-toxicity composite farm pesticide, which includes ether chrysanthemic ester, for preventing and controlling the pest of rice ash fly cootie, rice leaf folder, rice stem borer and yellow rice borer. The pesticide contains 0.5-20 wt.% of active components ether chrysanthemic ester, 2-30 wt.% of active components triazophos, 2-50 wt.% of chlorpyrifos, 2-50 wt.% of fenitrothion, 2-50 wt.% of diazinon, 10-60 wt.% of acephate, 20-60 wt.% of thrichlorfon, 5-50 wt.% of monosultap, 5-15 wt.% of emulsification, and the rest is solvent. The advantage of the composite farm pesticide is: 1) The effect is improved highly for controlling the pest of rice ash fly cootie and rice leaf folder; 2) One kind of agricultural chemicals can controlling various pests, and can prevent and control various pests at the same time. Agricultural chemicals' cost and work time being reduced. 3) High poisonous such as phosphorus methylamine insecticide can be replaced and the dosage of agricultural chemicals can also be reduced. Environment pollution and the rudimental pesticide of rice and marine lives can be reduced efficaciously. 4) The singular drug-fast capability of the pests such as rice leaf folder and rice ash fly cootie is restrained.

Description

1. Technical field [0001] The invention belongs to the technical field of pest chemical control, and in particular relates to a kind of high-efficiency compound insecticide containing etofenproxil, which is used for preventing and controlling various rice pests such as brown planthopper, rice leaf roller, rice stem borer and rice stem borer. . 2. Technical background [0002] The brown planthopper, Laodelphax striatellus Fallèn, is a vector insect that spreads rice stripe leaf blight, rice, wheat, corn black-streaked dwarf, wheat bush dwarf and other gramineous crop virus diseases. In recent years, the occurrence of SBPH in Jiangsu Province has caused a large epidemic of rice stripe leaf blight and brought serious losses to rice production. For a long time, the control of SBPH has mainly relied on imidacloprid, dichlorvos and other pesticides. Among them, imidacloprid has a slow control effect, and the overall control effect is not ideal. Dichlorvos has a certain quick effe...
