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, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all of them will show some defects and problems. limitation

Abstract

The invention discloses a paddy field weeding composition. The paddy field weeding composition is prepared from the following effective components in weight percentage: 1-10% of bensulfuron methyl, 1-10% of penoxsulam and 1-15% of cyhalofop-butyl, as well as the balance being pesticide adjuvants. The paddy field weeding composition disclosed by the invention has the advantages that after the bensulfuron methyl, the penoxsulam and the cyhalofop-butyl are compounded, a weeding effect is improved and a herbicide controlling spectrum is amplified; the toxin is low and the residue is low; the dosage, the medicine use times and the use cost are obviously reduced; and the effect of the composition is obviously higher than that of each single dosage and the composition is a current novel composition medicament which has good effect on preventing and treating annual weeds of a paddy field.

Description

Technical field [0001] The present invention involves a paddy field weed composition, which is based on sulfuron, split -sulfonal, and cyanofluorosyl ester as an active ingredient to prevent and treat the one -year weeds of rice fields. Background technique [0002] Chemical method weeding is one of the main means to control weeds in agriculture.In recent years, due to the large -scale use of some herbicide varieties, many weeds have produced anti -drug resistance.At the same time, the weeds of weeds are complicated. Herbal weeds, broad -leaved weeds, and paradise multi -category weeds are mixed. The use of a single variety of herbicides cannot solve the weeds of farmland.limitation.Different types of herbicides are mixed, with a wide range of weless spectrums, improving the actual effect, delaying weeds to resist drug resistance, and saving time and labor.
