Abstract
The invention discloses a hot fogging concentrate containing cypermethrin, which is prepared by using cypermethrin or the mixture of cypermethrin and an active component II as the effective constituent, and adding accessory ingredient and solvent, wherein the active component II is any one of chlorpyrifos, dimethoate and nitenpyram. By using the cypermethrin as the effective constituent, the hot fogging concentrate comprises the following components by weight percent: 1.6-30% of cypermethrin, 1-20% of accessory ingredient and the balance of solvent. By using any one of the cypermethrin and the active component II as the effective constituent, the hot fogging concentrate comprises the following components by weight percent: 0.1-20% of cypermethrin, 0.1-40% of active component II, 1-20% of accessory ingredient and the balance of solvent. The hot fogging concentrate disclosed by the invention is applicable to a hot fogging machine for preventing insect pests on sugarcane, corn, tobacco, fruit trees and forests. The hot fogging concentrate has the advantages of high working efficiency, strong knock-down activity, synergetic effect, good preventing effect, simpleness in operation, water and labor saving, safety, environmental friendliness, and the like.
Description
technical field [0001] The invention belongs to the technical field of pesticides, in particular to a thermal mist containing cypermethrin. Background technique [0002] Aphids (aphid), also known as honey worms, putty insects, etc., belong to the family Aphididae of the order Homoptera, and are pests with piercing and sucking mouthparts. At present, there are about 4,700 species known in the world, and about 1,100 species are distributed in China. Its body is small and soft, the size of a needle, and there are tubular protrusions (abdominal tube) on the abdomen. It sucks plant juice and is one of the important plant pests. Often clustered on leaves, tender stems, flower buds, terminal buds, etc., they prick and suck juice, causing leaves to shrivel and curl, and in severe cases, cause branches and leaves to wither or even die the whole plant; aphids are also intermediate media of various plant viruses, causing plant flowers, Deformation of leaves and buds can cause outbrea...
