Synergic weeding composition

Abstract

The invention provides a synergic weeding composition comprising active components, namely a compound (A) and a compound (B), wherein the compound (A) is a compound of formula (I) as shown in the specification, or an agricultural salt or vinegar thereof; the compound (B) is selected from monosulfuron ester; the weight ratio of the compound (A) to the compound (B) is 50:1-1:50. The invention further provides application of the synergic weeding composition in preventing and inhibiting germination or growth of broad leaf weeds, cyperaceae weeds, grassy weeds and plants unexpected by rice, wheat,barley, rye, oilseed rape, low-erucic acid oilseed rape, beets, corn, turf, cotton, vegetables, sugarcane and soybeans.

Description

Technical field [0001] The present invention relates to a synergistic herbicidal composition. The invention also relates to a method for controlling undesirable plants. Background technique [0002] In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, the grass phase when weeds occur is complex. Graminous weeds, broadleaf weeds, and sedges are mixed. The use of a single herbicide cannot solve weeds in farmland, and they will all show certain defects and limitation. Therefore, there remains a need for compositions and methods that effectively control undesirable plants. [0003] At present, herbicides are limited by crop safety and have limited herbicidal spectrum. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in crop fields. On the other hand, the herbicide dosage is too large or the application is uneven. It is also likely to cause unaccep...
