Abstract
The invention discloses a composite herbicide, which comprises the following components in percentage by mass: 0.5 to 30 percent of trifloxysulfuron, 0.5 to 30 percent of pyrithiobac-sodium, 3 to 20 percent of quizalofop-p-ethyl, 3 to 20 percent of haloxyfop-p-methyl, 5 to 20 percent of auxiliaries, and 5 to 80 percent of solvent and/or carrier. A preparation method of the composite herbicide comprises the following steps: adsorbing the efficient haloxyfop-p-methyl with white black carbon; mixing absorbed haloxyfop-p-methyl with trifloxysulfuron, pyrithiobac-sodium, quizalofop-p-ethyl, the auxiliaries and the carrier; and crushing by virtue of airflow to obtain a wettable powder product. The composite herbicide has the beneficial effects that: a weed killing spectrum is enlarged, the weed killing effect is improved, and the safety to cotton and afterreap crops is good.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, particularly a kind of compound herbicide that contains multiple different organic compounds and preparation method thereof.
Background technology
Cotton is one of China's main economic crops, and effectively preventing and kill off and control the cotton field weed is one of main method that improves at present output of cotton.Be directed to the main weeds in cotton field: kitchen garden, acalypha copperleaf, Amaranthus retroflexus etc., main Pendimethalin, Acetochlor, the trefanocide etc. of adopting are prevented and treated at present, they mainly prevent and treat the broad leaved weed of grassy weed and part, and the weeds pesticide resistance is more and more stronger, but very poor for the control efficiency of weeds such as kitchen garden, acalypha copperleaf, Amaranthus retroflexus.In view of this, the main weeds in cotton field is broad leaved weed now, and mostly be use gramineous herbicide for the control of cotton field weed at present, and finding no the weed killer herbicide that cotton field broad leaved weed is prevented and treated, this defective has very big influence for the output of cotton.Be the output of raising cotton, the succession of controlling weeds group, this just need a kind ofly can not only prevent and treat cotton field grassy weed, can also effectively prevent and kill off the weed killer herbicide of cotton field broad leaved weed.
