The invention relates to a tribenuron-methyl and 2,4-D butyl ester compound wheat field herbicide, containing the following components in percent by weight: 50-75 percent of tribenuron-methyl and 2,4-D butyl ester and the balance of assistant, wherein the weight ratio of the tribenuron-methyl and the 2,4-D butyl ester is 1:5-12. The herbicide adopts assistants consistently used in the agricultural chemical field, such as
wetting agents, dispersing agents,
solid carriers and the like and can be made into various dosage forms of compound herbicides respectively, such as
wettable powder dosage form, missible
oil dosage form, oil suspending agent
dosage form and the like. The invention has the advantages that the synergized action is obvious, broad leaved weeds in wheat fields can be effectively prevented and killed off, and especially, the prevention effect of
weed Descurainia having
drug resistance in the wheat fields is increased; meanwhile, the
weed killing speed is increased, the safety to crops is increased and the
drug hazard is lowered, thereby enabling the wheat to be increased by 2.9-8.1 percent in yield and the cost to be reduced by 13.4-40 percent.
