Problems solved by technology

At present, because quinclorac has been widely used in my country for many years, continuous single use for many years has continuously strengthened the resistance of weeds. Even if the dosage is continuously increased, it is difficult to effectively control the occurrence of weeds in farmland (see CN105028444A, CN105145590A)
Also there is no report on the compound herbicide of pendimethalin, quinclorac and flufenazim

Abstract

The present invention relates to a weeding composition and applications thereof, wherein pendimethalin, quinclorac and flumioxazin are adopted as main components, and a weight ratio of the pendimethalin to the quinclorac to the flumioxazin is 10-200:1-50:0.1-8. According to the present invention, the weeding composition is used for the pre-closing treatment on the cotton field seedlings so as to prevent and remove poaceae weeds and broadleaf weeds, wherein the synergistic effect and the yield increasing effect are significant.

Description

technical field [0001] The invention belongs to the field of agricultural herbicidal compositions, and relates to a herbicidal composition containing pendimethalin, quinclorac and flutrafen. Background technique [0002] Pendimethalin (pendimethalin), also known as pendimethalin, trade name Bicaotong, CAS registration number: 40487-42-1, the structural formula is as follows: [0003] [0004] Pendimethalin is an aniline herbicide, which can effectively control annual grasses and certain annual broad-leaved weeds. Barnyardgrass, crabgrass, foxtail, bluegrass, quinoa, amaranth and other weeds in the field. The weed absorbs the drug through the germinating shoots, and the drug that enters the plant binds to tubulin to inhibit the mitosis of plant cells, thus causing the death of the weed. [0005] Quinclorac (Quinclorac), the trade name is barnyard grass net, other names are chloroquine acid, god hoe, barnyard grass death, fast killing barnyard, gram barnyard star, killing...
