A film spreading oil agent for controlling rice planthopper

Abstract

A film-spreading oil agent capable of preventing and curing rice planthopper comprises the components by weight percent: 10-60 percent of effective component, 3-85 percent of additive, 0-70 percent of filling material, 5-14 percent of water surface diffusant, and 0-15 percent of water, wherein the effective component is one, or combination of any two selected from chlorpyrifos, diazinon, dichlorvos, imidacloprid, thiamethoxam, clothianidin, thiacloprid, thiazoline, nitenpyram, dinotefuran, pymetrozine, isoprocarb, fenobucarb, metolcarb, methyl carbamate, sulfoxaflor and flonicamid, and the weight ratio of the two effective components under two ways is (1:10)-(10:1). The oil agent has the technical effects that the effect of preventing and curing the rice planthopper is improved, the operation is simple, labor and time are saved, no harm is caused for human body, and no pollution is caused for the ambient condition when the oil agent is applied; moreover, the utilization ratio of the effective component is improved, the labor intensity is reduced, the labor is saved, and the agricultural production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a film-spreading oil, in particular to a film-spreading oil for preventing and treating rice planthoppers. Background technique [0002] my country has a long history of planting rice and has a vast area. It is one of the main rice producing countries in the world. Rice planthopper is one of the main pests that harm rice. The adults and nymphs of rice planthopper are all clustered at the base of rice stems to suck the juice on the stems. The harm of rice planthoppers to rice, in addition to directly sucking the juice on the stalks, hindering the growth, and in severe cases, the rice clumps will wither, and even the dead stalks of the whole field will fall down. The eggs will also stab the plants and damage the transporting tissue. , interfere with nutrient transport and spread viral diseases. At present, the control of rice planthoppers usually adopts the traditional conventional...

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that conventional spraying methods cannot effectively prevent and treat rice planthoppers. In order to solve this problem, we have designed a film-spreading oil agent for preventing and treating rice planthoppers. For any spraying equipment, you only need to sprinkle the film-spreading oil directly on the water surface, which saves labor and time, has a clear target, improves the control effect on rice planthoppers, and will not cause harm to the human body or the surrounding area. The environment is polluted, the duration of effect is long, resistance is not easy to develop, the utilization rate of active ingredients is improved, labor intensity is reduced, manpower is saved, and agricultural production costs are saved
