Abstract

The invention discloses a weeding composition containing oxaziclomefone and pyrazosulfuron-ethyl. The weeding composition comprises the effective components: penoxsulam, pyribenzoxim, and the balance being pesticide auxiliary agents. The mass part ratio of oxaziclomefone to pyrazosulfuron-ethyl in the weeding composition is 1:20 to 20:1. The weeding composition can be prepared into a suspending agent, an oil suspending agent, a wettable powder or water dispersible granules according to needs of applications, and can be used for preventing and removing annual weeds in paddy fields. The effects of the composition on preventing and removing the weeds in the paddy fields are obviously superior to that of each single agent, the dosage is reduced, and the drug resistance of the weeds is delayed.

Description

technical field [0001] The invention relates to a herbicidal composition containing oxazimidone and pyrazosulfuron-methyl, which is used for preventing and treating annual weeds in paddy fields by taking oxaziclozone and pyrazosulfuron-methyl as active ingredients. 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, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. 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] Oxaziclomefone, also known as Qubai'an, English common name: oxaziclomefone, structural...
