Problems solved by technology

[0004] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
The inventors have found through research that the synergistic compounding of herbicides is an effective measure to expand the spectrum of weed control and improve the control effect, and no herbicidal composition related to the compounding of thfensulfuron-methyl and propachlor has been found so far.

Abstract

The invention discloses herbicidal composition containing thiencarbazone-methyl and propisochlor and an application of the herbicidal composition. The herbicidal composition takes thiencarbazone-methyl and propisochlor as main effective ingredients, and the mass ratio of propisochlor to thiencarbazone-methyl is (1:60)-(60:1). The herbicidal composition can be used for weeding of corn fields and particularly has the remarkable effects on control of gramineae weeds and broadleaf weeds in the corn fields. Compared with single agents, the herbicidal composition delays the resistance of weeds, haswide weeding spectrum and long lasting period and is safe to corn and succession crops on the premise that the pesticide effect is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a herbicidal composition containing thifensulfuron-methyl and propachlor and its application. Background technique [0002] Thiencarbazone-methyl is a sulfonylaminocarbonyl triazolinone herbicide and an inhibitor of acetolactate synthase, which can be used in wheat, corn and other gramineous plants to effectively control broadleaf and gramineous weeds . Thicarbazone-methyl has the advantages of low dosage, high activity and strong selectivity. [0003] Propisochlor, chemical name: 2-chloro-N-(isopropylmethyl)-N-(2-ethyl-6-methyl)phenylacetamide. Promethachlor is a plant germination inhibitor, suitable for dryland crops such as soybean, corn, sunflower, potato, sugar beet and pea to control annual gramineous weeds such as barnyardgrass, goosegrass, crabgrass, foxtail, etc. Broad-leaved weeds such as amaranth, velvetleaf, ...
