A kind of mixed herbicide containing promasulfuron-methyl, penoxsulam and bentazone and its application

Abstract

The invention provides a mixed herbicide containing propyrisulfuron, penoxsulam and bentazone and an application thereof. The mixed herbicide contains active components of the propyrisulfuron, the penoxsulam and the bentazone; the weight ratio of the propyrisulfuron to the penoxsulam to the bentazone is 1-40:1-20:1-100. The mixed herbicide provided by the invention can be used for controlling broadleaf weeds, gramineous weeds and nutgrass flatsedge.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a mixed herbicide containing promasulfuron-methyl, penoxsulam and bentazone and an application thereof. Background technique [0002] Promethazone-methyl is a pyrimidine-based sulfonylurea herbicide developed by Japan's Sumitomo Chemical. Although it has the same mechanism of action as other sulfonylurea herbicides, it is an acetolactate synthase (ALS) inhibitor, but it resists sulfonylurea Urea herbicides have a good control effect on weeds and are mainly used in rice fields to control gramineous and broad-leaved weeds. The product is used at a low dosage and is effective against certain weeds that are known to be resistant to sulfonylurea herbicides. Penoxsulam is a triazolopyrimidine sulfonamide herbicide, which can effectively control barnyardgrass, stephenia and annual Cyperaceae weeds, and is effective against many broad-leaved weeds, such as Heterocarpus marsh, Carp sausage , T...
