Abstract

The invention belongs to the technical field of pesticides and discloses weeding composition. Flumioxazin and propisochlor in the mass ratio being (1-30): (1-50) are taken as main effective components, and the mass percentage of flumioxazin and propisochlor in the weeding composition is 2%-80%. The invention further discloses preparation of wettable powder, water dispersible granules, a suspending agent and emulsifiable concentrate from the weeding composition. The weeding composition has the advantages of being wide in weeding spectrum, good in control effect, safe to use and low in cost and can be used for controlling and removing annual weeds in soybean fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a soybean herbicide composition. Background technique [0002] The mechanism of action of Flurafen Propyridine is that protoporphyrin accumulates in sensitive plants after being treated with Flurafen Propyridine, which leads to photosensitization and peroxidation of cell membrane lipids, which results in irreversible damage to cell membrane function and structure. In the field, the stems and leaves of sensitive weeds are necrotic after stem and leaf treatment, and die after sunlight; the buds of sensitive weeds are necrotic after soil treatment, and die after short-term sunlight, especially for broad-leaved weeds. effect. It is mainly used to control annual broad-leaved weeds and some gramineous weeds such as commelina, chrysanthemum, cocklebur, velvetleaf, purslane, weasel petal flower, succulent, crabgrass, antibranch amaranth, cypress, and cow Weeds, weeds of the genus Cheno...
