Herbicide prepared by binary compounding of oxyfluorfen and trifluralin and preparation method thereof

Abstract

The invention discloses a herbicide prepared by binary compounding of oxyfluorfen and trifluralin and a preparation method thereof. The herbicide consists of the following components in percentage by mass: 3 to 10 percent of oxyfluorfen, 10 to 30 percent of trifluralin, 5 to 15 percent of surfactant, 8 to 20 percent of emulsifying agent and the balance of solvent. The preparation method comprisesthe following steps of: in the mass ratio, adding solvent into the oxyfluorfen, and mixing and stirring; adding solvent into the trifluralin, and mixing and stirring; mixing and stirring the two mixtures; adding the emulsifying agent and the surfactant into a reaction kettle, stirring 10 to 15 minutes; adding the rest solvent, and stirring for 20 to 30 minutes; and standing, filtering, filling, and sampling and analyzing to obtain the finished product. The herbicide is a high-efficiency and broad-spectrum herbicide, and is used for tending tea gardens, orchards and young growth and preventingand removing weeds before and after seedlings come out after seeds of crops such as soybean, rape, potato, cotton, cabbage, hot pepper, sunflower and tobacco are sowed. 30 to 40 g of herbicide is used for each mu at one time, and can realize no weeds in the whole growth period of the crops; and the application cost is 56.4 to 44.3 percent lower than that of the oxyfluorfen and the trifluralin.

Description

technical field

[0001] The invention relates to a herbicide and a preparation method thereof, in particular to a herbicide obtained by binary compounding of diphenyl ether oxyfluorfen and aniline herbicide trifluralin and a preparation method thereof. Background technique

[0002] Oxyflufen is a contact herbicide that works in the presence of light. Pre-emergence and early post-emergence applications work best. Trifluralin is an aniline broad-spectrum herbicide, which is effective in controlling annual weeds in dryland crops. But you can't kill all the weeds at once. Contents of the invention

[0003] The purpose of the present invention is to solve the problem that the above herbicides cannot kill all the weeds at one time, and to provide a herbicide compounded with oxyfluorfen and trifluralin and its preparation method, referred to as "Baifu". Herbicide Sirius 5" and its preparation method.

[0004] The technical scheme that realizes the object of the present inventi...
