Abstract

The invention relates to a solid preparation of a novel sterilant herbicide composition employing saflufenacil and glyphosate and containing a herbicide auxiliary agent. The solid preparation comprises the two effective compositions saflufenacil and glyphosate, the auxiliary agent and a carrier. The two effective compositions saflufenacil and glyphosate account for 10%-70% by weight of the composition, and the weight ratio of saflufenacil to glyphosate is 1:5-1:40. The solid preparation of the herbicide composition containing saflufenacil and glyphosate employs a particulate agent, a wettable powder and a water-dispersable granule as a product form. The herbicide auxiliary agent is a combination of at least two or more of a plant-resource spray auxiliary agent, a plant-source SD auxiliary agent, an alkyl glycoside surfactant, a trisiloxane surfactant, a tallow amine surfactant, betain, amino oligosaccharin and a penetrating agent JFC. The herbicide composition containing the herbicide auxiliary agent has excellent control efficacy on common gramineae and broad leaf weeds, and especially on weeds generating drug resistance on herbicides such as glyphosate, sulfonylureas, triazines and the like.

Description

technical field [0001] The invention relates to the field of pesticides, and more particularly to a solid preparation of a herbicidal composition containing herbicide adjuvants, a preparation method and use thereof. The solid preparation not only has excellent quality control indicators, but also greatly improves the efficacy. Background technique [0002] Glyphosate, paraquat and other biocide herbicides are widely used in my country, but their extensive use in production has also brought many adverse effects. For example, the number of arthropod species was reduced by 10% after the application of gramoxol (paraquat) in cotton fields; the number of ground arthropod populations was also significantly reduced, and this effect lasted for 2 months after application, and it also induced the nucleation of blood cells in fish. An abnormality occurs, causing water pollution. Extensive use of glyphosate can lead to the dissolution of heavy metals in contaminated soil, which in turn...
