Problems solved by technology

However, each herbicide has specific types of weeds to control. Long-term continuous high-dose use of a single species or a single mode of action of chemical herbicides can lead to weed resistance or cause changes in weed species, weeds, and weeds. The rapid replacement of grass populations causes problems such as weed resistance and resistance evolution, which greatly increases the difficulty of chemical weeding in farmland

Abstract

The invention discloses a herbicide composition and applications thereof, wherein the herbicide composition comprises three active components of nicosulfuron, rimsulfuron and topramezone according toa weight ratio of is 1-27:1-27:1-27, the active components account for 0.1-95% of the weight of the herbicide composition, a carrier accounts for 5-99.9% of the weight of the herbicide composition, the dosage form of the herbicide composition is a water suspending agent, emulsifiable concentrate, aqueous emulsion, suspoemulsion, an oil suspending agent, soluble granules, soluble powder, water dispersible granules or wettable powder, and the herbicide composition is used for preventing and removing dicotyledonous weeds and monocotyledonous weeds in corn fields or sugarcane fields. According tothe invention, the herbicide composition has excellent synergistic effect, obviously enlarges the weeding spectrum, can prevent and control various weeds at the same time, reduces the use amount, reduces the pesticide use cost and enlarges the application range.

Description

technical field [0001] The invention relates to the technical field of compound pesticides, in particular to a herbicide composition containing nicosulfuron, rimsulfuron and oxaflumezone and an application thereof. Background technique [0002] With the rapid development of science and technology, chemical weeding, as a modern and practical technology, plays a huge role in weed control. Although the development of chemical weeding technology is not long, but the development speed is relatively fast. With the development of China's agricultural modernization and the gradual transfer of agricultural labor force, cultivation methods tend to be large-scale and intensive, and the demand for herbicides has increased significantly. [0003] At present, according to the needs of chemical weeding in farmland, a large number of herbicide varieties have been developed. However, each herbicide has specific types of weeds to control. Long-term continuous high-dose use of a single speci...
