The weeding composition comprises an active component composed of a compound (A) and a compound (B), wherein (A) is a compound as shown in a formula (I) which is defined in the specification while (B) is a compound as shown in a formula (II) which is defined in the specification, and a weight ratio of the compound (A) to the compound (B) is 1: 1 to 1: 100.

Description

Technical field [0001] The present invention relates to a herbicidal composition. The invention also relates to a method of controlling undesirable vegetation. Background technique [0002] There are many types of weeds in rice fields, and weeding in rice fields is a major problem in production. Chemical weeding is the main means of controlling weeds. However, 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. [0003] Propyrisulfuron is a pyrimidinyl sulfonylurea herbicide developed by Sumitomo Chemical of Japan. It is mainly used to control grass and broadleaf weeds such as barnyard grass in rice fields. This product has a low dosage and is very effective in controlling w...
