Abstract

The re-compounded pesticide for preventing and killing corn borer is used in preventing and killing Asiatic corn borer mainly. The re-compounded pesticide has chlorpyrifos and permethrine with specific effect on corn borer as the effective components, sand as carrier, diatomite as the coating agent and slow releasing material, and indicator. It is prepared into granule through the technological process including the steps of sieving sand, compounding, coating, colorizing and packing. It has the features of high effect, low toxicity and low residue.

Description

technical field [0001] The invention relates to an insecticide specially used for killing corn borer, in particular to a compound insecticide. Background technique [0002] Corn borer is a common pest in corn belts in the world, and its harm is seriously affecting the yield and quality of corn. Insect-resistant breeding, chemical control and biological control are usually used, but the control effect needs to be improved. Taking chemical control as an example, in the past, only highly toxic parathion, carbofuran, and phorate were used to control borers. Because of its high toxicity, it has been banned or will be banned by the country, and there is an urgent need for replacement products with high efficiency and low toxicity in production. Contents of the invention [0003] The object of the present invention is to provide a compound special insecticide for controlling corn borer, which minimizes the cost while ensuring the insecticidal effect, and has remarkable insectic...
