Abstract

The invention discloses a weeding composition containing topramezone and thiencarbazone-methyl as major active ingredients. The weight ratio of the active ingredients, topramezone to thiencarbazone-methyl, is 1: 40 to 40: 1; the total weight of the active ingredients is 2%-80% of the total weight of the composition; the produced preparation include a wettable powder or water dispersible granules, a suspending agent, an emulsion in water, and a microcapsule suspending agent. The weeding composition has double functions, is applicable to pre-emergence weeding or post-emergence weeding, weeds are not prone to generate resistance, and the weeding composition has obvious synergistic effect and continuous prevention and control effect. Meanwhile, the weeding spectrum and the application range are expanded; the weeding composition is applied to weeding not only in corn fields, but also in wheat, barley, soybean, potato, rape, spinach and garlic fields. The dosage of the weeding composition is reduced and the agricultural cost is decreased.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing fentrazone and thiazone-methyl as main active ingredients and an application thereof. Background technique [0002] Topramezone, chemical name 4-[3-(4,5-dihydroisoxazol-3-yl)-2-methyl-4-methylsulfonyl]-1-methyl-5 -Hydroxy-1H-pyrazole is a benzylpyrazolone herbicide developed by BASF and is a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor. It has a good control effect on weeds resistant to glyphosate, triazines, acetolactate synthase (AIS) inhibitors and acetyl coenzyme A carboxylase (ACCase) inhibitors. It is a broad-spectrum post-emergence herbicide and can Effectively control annual grasses and broad-leaved weeds in cornfields, and high doses can also have a certain inhibitory effect on Cyperaceae weeds. But it cannot be used for pre-emergence soil weeding. [0003] Thiencarbazone-methyl, chemical name methyl 4-[(4,5-dihydro-3-methoxy-4-me...
