Problems solved by technology

[0024] At present, there are not many herbicidal composition patents related to fenthuron and oxyfluorfen, only patents CN98808804.5, CN200380103804.4, CN200410043749.0, etc. These compound compositions are all aimed at weeds in paddy fields. Weeds in dryland crops such as sugarcane, peanuts and corn have not been found in related patents
At the same time, there is no patent on which Tethhiuron and Oxyflufen are used as active ingredients in the same patent

Abstract

A disclosed herbicide composition containing buthiuron and oxyfluorfen comprises the active components in percent by weight: 1%-50% of buthiuron and 0.2%-10% of oxyfluorfen. The balance is an additive. The preparation form of the composition can be wettable powder, water-soluble dispersive granules, granules, missible oil, micron emulsion, emulsion in water and suspending agents. The composition can be applied before dry-land crops such as sugarcane, peanut, corn and the like are budded, is capable of controlling majority annual weeds, overcomes the disadvantage that some annual weeds generate resistance to acetochlor at present, and helps to reduce the use amount of atrazine and attenuate the risk of atrazine on health of human and other kinds of animals.

Description

Technical field: [0001] The invention belongs to the technical field of pesticide formulations, and specifically relates to a pesticide herbicide composition and a production method thereof, which are herbicides applied to upland crops with tetrathhiuron and oxyfluorfen as active ingredients and a production method thereof. technical background: [0002] At present, there are few herbicides used as pre-emergent seals on dryland crops in the south, mainly acetochlor and atrazine. These two herbicides have been used for many years. With the emergence of weed resistance, the effect is becoming more and more effective. worse. Moreover, atrazine has a long residual period, and it is easy to leach into groundwater, causing pollution and causing health risks to humans and other types of animals. Therefore, this agent has been phased out in Europe. [0003] Therefore, it is necessary for us to develop a new pre-emergent herbicide applied to dryland crops in the south. According to...
