Abstract

The invention discloses a weeding composition containing oxaziclomefone and mesotrione. The effective constituents are oxaziclomefone and mesotrione, and the rest are pesticide adjuvants. The mass fraction ratio of oxaziclomefone to mesotrione in the weeding composition is 1:30-30:1. The weeding composition can be prepared into suspending agents, oil suspending agents, wettable powder or water dispersible granules according to the application needs to prevent and kill off annual weeds in paddy fields. The composition is much better than single oxaziclomefone or mesotrione in preventing and killing off weeds in paddy fields, the dosage can be reduced, and the drug resistance of weeds can be postponed.

Description

technical field [0001] The invention relates to a pesticide herbicide composition, which uses oxaziclozone and mesotrione as active ingredients, and is used for preventing and controlling annual weeds in paddy 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, 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 formula: [0004] [0005] Oxazimidone belo...
