Spreading oil for controlling Lissorhoptrus oryzophilus Kuschel

Abstract

The invention relates to a spreading oil for controlling Lissorhoptrus oryzophilus Kuschel. A technical scheme adopted in the invention is characterized in that the spreading oil comprises 10-60wt% of an effective component, 3-80wt% of an assistant, 0-70wt% of a filler, 5-10wt% of a water surface dispersing agent and 0-10wt% of water, wherein the effective component comprises one or two of chlopyrifos, diazinon, dichlorvos, imidacloprid, thiamethoxam, clothianidin, thiacloprid, thiazoline, nitenpyram, dinotefuran, pymetrozine, isoprocarb, fenobucarb, MTMC, dimethacarb, ethofenprox, carbosulfan, sulfoxaflor and flonicamid, and the weight ratio of the above any two is (1:10)-(10:1) when the effective component combines the above two. The spreading oil has the advantages of simple operation during drug application, labor and time saving, improvement of the utilization rate of the effective component and the control effect on the Lissorhoptrus oryzophilus Kuschel, no harms to human bodies, labor intensity reduction, manpower saving, and saving of the agricultural production cost.

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 water weevil. Background technique [0002] Rice water weevil, also known as rice water weevil and rice root weevil, is a second-class quarantine pest in China. It is native to North America. Its most important host plant is rice. The adults of rice water weevil can migrate more than 10,000 meters by airflow. It can also spread with the water flow. The adults gnaw on the rice leaves, and the larvae migrate from the grassland to the rice field to eat the rice roots. Generally, the rice yield is reduced by 15-20%, and the serious one is more than 50%, or even no harvest. At present, the control of rice water weevil usually adopts the traditional conventional spraying method, but the conventional spraying method is not only labor-intensive and time-consuming, but also requires a large amoun...

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem that the conventional spraying method is less effective to the control of rice water weevil. In order to solve this problem, we have designed a kind of film-spreading oil agent for preventing and treating rice water weevil, which is simple to operate during application. No need for any spraying equipment, just spray the film-spreading oil directly on the water surface, saving labor and time, with clear targets, improving the control effect on rice water weevil, and will not cause harm to the human body. It will pollute the surrounding environment, has a long duration, is not easy to produce resistance, improves the utilization rate of active ingredients, reduces labor intensity, saves manpower, and saves agricultural production costs
