Abstract
The invention relates to a composition and method for preventing and removing pests, and particularly relates to a composition and method for preventing and removing pests, capable of preventing and controlling various underground pests and soil diseases effectively and simultaneously. The composition for preventing and controlling pests is characterized by containing active components and an adjuvant, wherein the active components are a pesticide chlorpyrifos and a bacteriacide captan and the weight ratio of chlorpyrifos to captan is (50:1)-(1:50), and the active components, namely chlorpyrifos and captan, account for 5-80wt% of the composition. In the method for preventing and removing pests, chlorpyrifos and captan act on pests at the same time, or any one of chlorpyrifos and captan isused to act on the pests at first and then the other one is used to act on the pests.
Description
[0001] technical field [0002] The pest control composition and pest control method of the present invention relate to a pest control composition and pest control method that can effectively control various underground pests and soil diseases at the same time. Background technique [0003] Chlorpyrifos (chlorpyrifos), chemical name 0,0-diethyl-0 (3,3,6-trichloro-2-pyridyl) phosphorothioate, is an acetylcholinesterase inhibitor, belonging to the phosphorothioate class of killing Insecticide with contact killing, stomach killing and fumigation effects. Stem and leaf spray can be used to control rice planthoppers, rice leaf rollers, rice stem borers, citrus tree scale insects, cruciferous vegetables Spodoptera litura, wheat aphids, etc. The residual period on the leaves is not long, but the residual period in the soil is longer, and the control effect on underground pests is good. [0004] Captan, a broad-spectrum organosulfur fungicide, has both protective and therapeutic ef...
