Abstract

The invention discloses a composite herbicide, which comprises the following components in percentage by mass: 5 to 60 percent of oxadiazon, 3 to 50 percent of oxyfluorfen, 5 to 70 percent of butachlor, 1 to 20 percent of auxiliaries, and 5 to 80 percent of solvent or carrier. A preparation method of the composite herbicide comprises the following steps: putting the oxadiazon and the oxyfluorfen technical into a preparation kettle; adding the solvent to dissolve the oxadiazon and the oxyfluorfen technical while stirring; sequentially adding the butachlor, the auxiliaries and the solvent; and uniformly stirring to obtain an emulsifiable solution product. The composite herbicide has the advantages that: the oxadiazon, the oxyfluorfen and the butachlor belong to different types of herbicideswith different functions and characteristics, prevent weeds from generating drug resistance after compounded, have complementary advantages to enlarge the range of weed control, in particular to noxious weeds difficult to control insects, and can postpone and control the drug resistance of weeds and succession of weed community in the field; and the herbicide composition has good safety to plantsand afterreap crops.

Description

technical field [0001] The invention relates to a herbicide, in particular to a compound herbicide containing oxadiazone, oxyfluorfen and butachlor and a preparation method thereof. Background technique [0002] At present, the main herbicides in rice fields are ethylbenzyl, butylbenzyl and dichlorobenzyl. Due to the long-term use of more and more resistant weeds, the crops have been greatly reduced; the herbicides in cotton fields are mostly soil treatment agents, mainly Acetochlor and trifluralin are the main ones. With the continuous use of acetochlor and trifluralin for a long time, more and more weeds are resistant to them. Since acetochlor is a selective herbicide, it leads to The number of sensitive weeds decreased significantly, while the number of insensitive weeds gradually increased, causing significant changes in the weed community. In view of the current severe situation, it is urgent to find a herbicide combination that is safe for rice and cotton and highly e...
