Abstract
The invention discloses a composition for preventing and treating underground insects. The composition is characterized in that effective insect killing constituents are benfuracarb and chlorfenapyr, the weight ratio of the benfuracarb to the chlorfenapyr is 1-40: 1-40, the effective constituents account for 1%-80% of the total weight of the composition, and the composition comprises granules or wettable powder, water dispersible granules, suspending agents, emulsion in water and microcapsule suspending agents according to the dosage forms processed through a pesticide dosage form machining method. The chlorfenapyr and the benfuracarb of the effective insect killing constituents are compounded, then have the dual-acting mechanisms, and have the obvious effect increasing function and the continuous prevention and treatment effect for preventing and treating underground insects, the insecticidal spectrum is enlarged, underground insects like nematodes and grubs can be prevented and treated, the use range is enlarged, the composition can also be used for crops like corns and vegetables, and the pesticide dosage is reduced.
Description
technical field [0001] The invention relates to a composition for controlling underground pests. Background technique [0002] Subterranean pests refer to omnivorous insects that live in the soil and harm the underground parts of plants, seeds, seedlings or main stems near the soil surface during their whole life or at a certain stage of their life. There are many types, mainly mole crickets, grubs, day lily bugs, cutworms, root maggots, root bugs, root aphids, pseudo-crickets, crickets, root scales, root leaf beetles, root beetles, root weevils and termites, etc. More than 10 types , a total of about 200 species. [0003] Benfuracarb is a low-toxic derivative of carbofuran, which has systemic, contact and gastric toxicity. It can be widely used to control rice water weevil, thrips, core borer, cotton aphid, onion fly, diamondback moth, etc. It can be used as a soil treatment agent to control underground pests and foliar pests. Carbosulfan formulations are: 3%, 5%, 10% gr...
