Abstract

The invention belongs to the technical field of pesticides, relates to the compounding technology of pesticides and particularly relates to a compounding technology of flumioxazin and amidosulfuron and an herbicidal composition of flumioxazin and amidosulfuron and its application. The herbicidal composition comprises flumioxazin and amidosulfuron according to a weight ratio of 50: 1 to 1:10. The herbicidal composition comprises 3-80% by weight of the active ingredients and the balance of pesticide allowed and acceptable auxiliary ingredients. Through compounding of flumioxazin and amidosulfuron in a certain ratio, the obvious synergistic effect is obtained. The herbicidal composition can be used for preventing and controlling broad-leaved weeds such as purslane, acalypha australis, Lithospermum arvense, cephalanoplos seyetum, nightshade, chenopodium album, Calystegia hederacea, flixweed and cleavers in the wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the compounding technology of pesticides, in particular to the compounding technology of flumechlor propinyl and sulfuron-methyl, which is a herbicidal composition of flumechlor propinyl and rimsulfuron-methyl and its application . Background technique [0002] Propyramide [0003] Molecular formula of flurafen propargyl: C 19 h 15 FN 2 o 4 , relative molecular weight: 354.3318, density: 1.48g / cm 3 , Boiling point: 644.4°C at 760mmHg, flash point: 343.5°C, vapor pressure: 1.69E-16mmHg at 25°C. [0004] Structural formula: [0005] [0006] Flurafen propargyl is a herbicide absorbed by young shoots and leaves. It can effectively control annual broad-leaved weeds and some grass weeds when used as soil treatment. It is easy to degrade in the environment and is safe for subsequent crops. Soybeans and peanuts have good resistance to it. Corn, wheat, barley, rice are moder...
