Abstract

The invention discloses a synergistic weeding composition for preventing and removing weed in a paddy field. The synergistic weeding composition contains 1 to 20wt% of cyclosulfamuron, 1 to 20wt% of penoxsulam and 1 to 30wt% of cyhalofop-butyl as active ingredients. The synergistic weeding composition for preventing and removing weed in a paddy field has weeding effects obviously superior to effects of all single-ingredient weeding agents, has a wide weeding spectrum, improves a real effect, delays herbicide resistance of weed and saves time and labor.

Description

technical field [0001] The invention relates to a synergistic herbicidal composition for preventing and controlling weeds in paddy fields, which uses cyprosulfuron-methyl, penoxsulam and cyhalofop-ethyl 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] Cyprosulfuron, English name: cyclosulfamuron, chemical...
