Abstract

The invention discloses a weeding composition for a sugarcane field. The composition comprises a component (a) and a component (b), wherein the component (a) is trifloxysulfuron, the component (b) is at least one of atrazine, ametryn and propisochlor, and the weight ratio of the component (a) to the component (b) is 1:1-30. Through mixed use of the trifloxysulfuron and the atrazine, the ametryn or the propisochlor, the weeding composition for the sugarcane field broadens a herbicidal spectrum, reduces the drug dosage of a single ingredient, not only can prevent a majority of broadleaf weeds and a part of macrophanerophytes weeds, but also can achieve special effects on cyperaceae weeds and cyperus rotundus, make up for the deficiency of single use of the respective ingredient and have favorable prevention and control effects.

Description

technical field [0001] The present invention relates to a herbicidal composition for sugarcane fields, in particular to a herbicidal composition compounded with trifluxysulfuron-methyl and one or more of atrazine, ametryn, and propachlor , belongs to the technical field of pesticides. Background technique [0002] Sugarcane is a plant of the grass family Saccharum, native to tropical and subtropical regions. Sugarcane is a plant with high light efficiency, high light saturation point, low carbon dioxide compensation point, low photorespiration rate, and high photosynthetic intensity, so sugarcane has high biological yield and large profits. Sugar cane is produced in more than 100 countries around the world, and sugar cane is the main raw material for sugar production in my country. Therefore, effective and safe control of sugarcane weeds and improvement of sugarcane yield are also important topics in the pesticide industry. [0003] Trifloxysulfuron-methyl, its mechanism ...
