Abstract

The invention relates to a weeding composition. The invention also relates to a method for controlling unwanted plants. 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 undesired vegetation. Background technique [0002] There are many kinds of weeds in paddy fields, and weeding in paddy fields is a major problem in production. Chemical weed control is the main means of weed control. However, 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 will show some defects and limitation. [0003] Propyrisulfuron is a pyrimidine-based sulfonylurea herbicide developed by Sumitomo Chemical, Japan. It is mainly used in rice fields to control gramineous and broad-leaved weeds such as barnyardgrass. The product is used at a low dosage and is effective against cert...
