Abstract

The invention belongs to the technical field of pesticide, and relates to a weeding composition, which is characterized by comprising two active components propyrisulfuron and penoxsulam, and the weeding composition is obvious in weeding effect, long in duration, wide in weeding spectrum and safe to rice and has an obvious synergic action.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition of promasulfuron-methyl and penoxsulam. Background technique [0002] 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 certain weeds that are known to be resistant to sulfonylurea herbicides. The structural formula is as follows: [0003] [0004] Penoxsulam is a post-emergence herbicide developed by Dow AgroSciences in the United States. It is a triazolopyrimidine sulfonamide herbicide and works by inhibiting acetolactate synthase (ALS). . Penoxsulam is a conductive herbicide, which is absorbed by stems, leaves, young shoots and roots, and then transmitted to meristems through xylem and phloem to inhibit plant growth and mak...
