Weeding combination containing anilofos and quinclorac or quinclorac salts and preparation thereof

Abstract

The invention relates to a weeding combination containing anilofos and quinclorac or quinclorac salts and a preparation thereof. Particularly, the weeding combination is used for controlling and eliminating vicious weeds such as paddy field barnyard grass, moleplant seeds, paspalum distichum and crabgrass and has good control effects on the barnyard grass with the leaf age of over 5.5, the paspalum distichum, the moleplant seeds and the crabgrass and other annual weeds. The combination comprises, by weight, 1-70% of anilofos and 1-99% of one or more than one of quinclorac and the quinclorac salts. The weeding combination has the good control effects on the barnyard grass with the leaf age of over 5.5, the paspalum distichum, the moleplant seeds and the crabgrass and other annual weeds, the equipment investment is little, a process is easy to control, product quality is stable, the weeding combination can be produced continuously and is suitable for industrial production, and the yield is higher than 99%.

Description

technical field [0001] The invention relates to a pesticide herbicide composition, which is specifically used for controlling malignant weeds such as rice barnyardgrass, daughter of a daughter, bispacia paspalum, crabgrass, etc. The annual weeds such as , paspalum, daughter, and crabgrass have good control effect. Background technique [0002] Occurrence and damage of rice barnyard grass: an annual herb. Companion plants of rice. Due to human irrigation, fertilization, intertillage and weeding of rice, threshing and winnowing after harvest, it has a well-developed root system, water-loving and fertilizer-loving, and dense tillering. The leaves grow vertically, and the leaf sheaths are green and green. The seeds are relatively large; regardless of its seedlings, adult plants and seeds, it can be mixed with rice and harm rice for a long time. Other characteristics are similar to barnyardgrass. It is only found in paddy fields and is a serious weed in paddy fields. [0003...

AI Technical Summary

Problems solved by technology

[0005] Due to long-term, single use or abuse of herbicides in agricultural production, some weeds have developed resistance to herbicides, and even developed cross-resistance and multiple resistance, making many pesticide varieties useless

However, the research and development cycle of new pesticides is long, and they are often not available, which is a major obstacle to agricultural production.
