Abstract

The invention relates to a flufenacet-containing post-emergence compound herbicide for corn fields. The compound herbicide is prepared from 1.5-24% by weight of flufenacet, 5-50% by weight of mesotrione, 0.5-19% by weight of thifensulfuron methyl, 4-23% by weight of an auxiliary agent and 27-88% by weight of a solvent and / or a carrier. The total weight of the flufenacet, the mesotrione and the thifensulfuron methyl is 8-80% of the total weight of the compound herbicide. Beneficial effects of the compound herbicide are that combination of the flufenacet, the mesotrione and the thifensulfuron methyl can effectively overcome a malignant weed control problem for corn fields, the compound herbicide is particularly suitable for post-emergence weed control of the corn fields, the compound herbicide is small in using amount, easily degradable, short in residual period in soil and good in safety for corn and afterreap crops, and the compound herbicide delays and controls drug resistance of weeds and field weed community succession.

Description

technical field [0001] The invention relates to a herbicide, in particular to a post-emergence compound herbicide containing flufenacet for corn fields and a preparation method thereof. Background technique [0002] Corn is an important food crop and an important feed crop in my country. In recent years, with the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn has continued to increase. In 2009, my country's corn planting area reached 28.5 million hectares, ranking third after rice and wheat planting area, and there is still an increasing trend. [0003] Weeds in cornfields are common and of various types. Grass damage occurred seriously in spring corn in Northeast China and summer corn in Huanghuai and Haihai. The area of ​​weed damage accounted for 82%-96% of the planting area in this area, and the area of ​​moderate damage was 64-66%. Maize seedlings are most seriously damaged by weeds, and weed...
