Herbicide compound containing mesotrione and terbuthylazine and preparation method thereof

The invention provides herbicide compound containing mesotrione and terbuthylazine and a preparation method thereof. The herbicide compound comprises mesotrione and terbuthylazine, agricultural emulsifier 1601 is adopted as the emulsifier, resin-based vegetable oil is adopted as the synergist, and the rest is oil suspension filler methyl oleate or suspending agent filler water. The resin-based vegetable oil is added as the synergist, so that the pesticide effect can be significantly improved. The compound has very significant synergistic effect compared with two type of single dosage, i.e. mesotrione and terbuthylazine. The overall pesticide effect is obviously better than the mixture of single dosage. The prevention effect of the herbicide compound to gramineous weeds is 80.1 percent to 99.6 percent; and the prevention effect of the herbicide compound to broad-leaved weeds is 88.9 percent to 100.0 percent. The integrated prevention effect of the mesotrione is 67.7 percent to 69.7 percent; the integrated prevention effect of the terbuthylazine is 49.5 percent to 53 percent; and the integrated prevention effect of the herbicide compound is 83.5 percent to 99.9 percent. The herbicide compound can be prepared into oil suspension and suspending agent.
