Problems solved by technology

In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance
At the same time, when weeds occur, the grass phase is complex, a variety of weeds are mixed, and the use of a single species of herbicide cannot solve the weeds in the farmland, which will show some defects and limitations

Abstract

The invention discloses a weeding composition containing prosulfuron. The weeding composition comprises effective components of prosulfuron, bromoxynil octanoate and atrazine. A weight percentage of prosulfuron in the composition is 0.1%-20%, a weight percentage of bromoxynil octanoate in the composition is 0.1%-30%, and a weight percentage of atrazine in the composition is 0.1%-50%, with the balance being pesticide adjuvants. According to requirements, the weeding composition can be prepared into one of a dispersable suspending agent, a suspending agent, wettable powder and water dispersible granules. The weeding composition has an effect obviously superior to that of each single reagent for annual weeds in a corn field, reduces use amount of pesticide, and prolongs pesticide resistance of the weeds.

Description

technical field [0001] The invention relates to an agricultural herbicide, the active ingredients of which are fluorsulfuron, bromoxynil and atrazine, which are used for controlling annual weeds in corn fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, a variety of weeds are mixed, and the use of a single herbicide can not solve the weeds in the farmland, which will show some defects and limitations. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, and saving time and labor. [0003] Flusulfuron belongs to the sulfonylurea herbicides, which can inhibit the synthesis of weed branched-chain amino acids, thereby inhibiting the biosynthesis o...
