Weeding composition containing diflufenican and tembotrions

Abstract

The invention relates to a weeding composition containing diflufenican and tembotrions. A preparation of the weeding composition contains two active components tembotrions and diflufenican at the ratio in parts by weight of 1 to (0.01-60); the two active components accounts for 1%-75% of the overall preparation in parts by weight; and the weeding composition can be prepared into the pesticide preparation forms: wettable powder, a suspending agent, missible oil, a microemulsion, an emulsion in water, granule and a water dispersible granule. The weeding composition disclosed by the invention has a significant synergistic effect; the persistence of each component of single dosage is improved; the herbicide resistance is obviously delayed; the repeated utilization frequency of the pesticide is reduced; the use amount is reduced; the agricultural cost is reduced; the weeding composition is safe to crop, easy to degrade in the environment after the lasting period; the safety of the composition on the next-stubble crops is improved; and the weeding composition has important significance on protection of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing diflufenican and tembotrione. Background technique [0002] Triketone is a new type of triketone herbicide, which is also an HPPD inhibitor, and is mainly used for weeding in corn fields. Its chemical structural formula is: [0003] . [0004] The chemical name of diflufenamide is 2,4-dichloro-2-(α,α,α-trichlorofluoro-m-phenoxy)-3-pyridineanilide, which belongs to carotenoid biosynthesis inhibitors and absorption agents The content of carotenoids in the weed plants decreases, resulting in the destruction of chlorophyll, the rupture of cell membranes, the weeds appear as discolored or white buds, and finally the whole plant wilts and dies. It is a broad-spectrum selective wheat field herbicide. It can control gramineous and broad-leaved weeds, especially pig scorpion, Polygonum curcuma, purslane, black nightshade, chickweed,...

AI Technical Summary

Problems solved by technology

Experiments have confirmed that the two have a strong synergistic effect, and there is no relevant report at home and abroad on whether tembotrione can be compounded with diflufenican as the active component.
