Problems solved by technology

[0006] Penoxsulam belongs to the class of triazolopyrimidine sulfonamide herbicides. It works by inhibiting acetolactate synthase (ALS). Accumulation of growth points inhibits the synthesis of acetolactate synthase, resulting in the inability to synthesize branched-chain amino acids, which in turn affects protein synthesis and weed cell division, causing weeds to stop growing and then die. dying gradually

Abstract

The invention relates to a paddy field weeding granule containing penoxsulam, mefenacet and bensulfuron methyl as well as a preparation method and application of the paddy field weeding granule. The granule comprises a A-phase component, a B-phase component and a C-phase component, wherein the A-phase component comprises 70%-95% of a granule carrier, the B-phase component comprises 0.1%-30% of functional mother powder containing three active ingredients, namely penoxsulam, mefenacet and bensulfuron methyl, and the C-phase component contains 1%-40% of a coalescing agent; and the coalescing agent comprises a binder, an inducer and a warning color. The paddy field weeding granule containing penoxsulam, mefenacet and bensulfuron methyl is scientific and reasonable in design, is prepared by a coating film forming method, is good in film forming, glossy, good in wear resistance, free of caking, falling and dust, high in safety, capable of being separately spread, capable of being mixed witha fertilizer to be spread, convenient, rapid, easy to operate and capable of reducing labor.

Description

technical field [0001] The invention belongs to the field of chemical pesticide production, and relates to paddy field weeding and pesticide technology, in particular to a paddy field weeding granule containing penoxsulam, mefenacet, and bensulfuron-methyl, a preparation method and application thereof. Background technique [0002] Rice is a very important food crop in my country, and its sown area accounts for the first place in food crops. Paddy weeding is a major problem in production. Chemical weeding is currently the main means of controlling weeds. In recent years, due to the large-scale single-use of some herbicide single-dose varieties, many weeds have developed resistance and the herbicide spectrum has narrowed. At the same time, due to the complex and various types of weeds when weeds occur, and the use of these pesticides for a long time, the dosage of pesticides has increased year by year, which has caused the original weak grass system in the paddy field to gr...
