Problems solved by technology

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

Abstract

The invention discloses a weeding composition containing benzobicyclon and oxadiargyl and application of the weeding composition. The weeding composition comprises the main effective ingredients of benzobicyclon and oxadiargyl, and a mass ratio of oxadiargyl and benzobicyclon is 1:60-60:1. The weeding composition can be used for weeding a paddy field and particularly has an obvious effect for preventing and weeding cyperaceae weeds broadleaf weeds and gramineae weeds in the paddy field. Compared with a single dosage, on the premise of improving the efficacy, the weeding composition has the effects of delaying the resistance of the weeds, being wide in a weeding spectrum and long in lasting period and being safe for paddies and after-reap crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a herbicidal composition containing benzobicyclone and propargyl oxadiazone and its application. Background technique [0002] Benzobicyclone is a pyrazole herbicide newly developed by Sumitomo Corporation. Its mechanism and mode of action: it is absorbed through roots, stems, young shoots, and leaves and is rapidly transmitted. After absorption, it inhibits the biosynthesis of weed chlorophyll. It has high activity, strong selectivity, and broad spectrum. [0003] Propylene oxadiazone can effectively control firefly grass, barnyardgrass, wild water chestnut, broken rice sedge, special-shaped sedge, cow felt, knotweed, small barnyardgrass, daughter, three-edge grass, duck tongue grass, rain for a long time Annual grass weeds, broadleaf, Cyperaceae weeds and Spirogyra in paddy fields such as flowers, Alisma, dwarf Arrowhead,...
