Abstract

The invention belongs to the technical field of pesticide, and discloses a weeding composition. The weeding composition is prepared from the main effective ingredients of bicyclopyrone and nicosulfuron according to a mass ratio of (1 to 40):(1 to 50), and the sum of weight percentage of bicyclopyrone and nicosulfuron is 10 to 80% in the weeding composition. The weeding composition provided by the can be prepared into wettable powder, a water dispersion granule, an oil suspension and a water suspension. The weeding composition has the advantages that the weeding spectrum range is broad, the preventing effect is good, the persistence and rapidity are better, and the weeding composition can be used for preventing and removing field weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition for preventing and controlling annual weeds in cornfields with synergistic synergistic effect of the two-component combination of flufenazol and nicosulfuron. Background technique [0002] Corn is one of the three major food crops in my country and is planted all over the country. There are many factors that affect corn production, and weeds are one of them. Although the weed community in cornfields is affected by factors such as farming methods, planting methods, sowing density, and soil fertility, the dominant weeds in cornfields in various parts of my country at this stage are mainly goosegrass, crabgrass, foxtail, barnyardgrass, and reverse branch. Amaranth etc. mainly. [0003] Nicosulfuron is a sulfonylurea herbicide developed by Ishihara Sangyo Co., Ltd., which inhibits the synthesis of branched-chain amino acids by inhibiting the a...
