Weeding composition containing benzobicyclon and isoproturon and application thereof

Abstract

The invention discloses a weeding composition containing benzobicyclon and isoproturon and application thereof. The weeding composition takes the benzobicyclon and the isoproturon as main effective components and the mass ratio of the isoproturon to the benzobicyclon ranges from (1 to 60) to (60 to 1). The weeding composition disclosed by the invention can be used for weeding paddy fields and especially has a remarkable effect on prevention and control of grassy and broadleaf weeds in the paddy fields. Compared with a single dosage, the weeding composition disclosed by the invention has the advantages that the weed resistance is delayed under the condition that the pesticide effect is improved, the weeding spectrum is wide and the lasting period is long; the weeding composition is safe to rice and succeeding 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 isoproturon and an application thereof. 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] Isoproturon, chemical name: 3-(4-isopropylphenyl)-1,1-dimethylurea, structural formula: [0004] [0005] Isoproturon is a selective herbicide that can be used both before and after emergence. Used for wheat, barley, cotton, corn, soybean, pea, broad bean, peanut and other crops to prevent and control weeds such as melon, crabgrass, wild oats, quinoa, bluegrass...

AI Technical Summary

Problems solved by technology

Used for wheat, barley, cotton, corn, soybean, pea, broad bean, peanut and other crops to prevent and control weeds such as melon, crabgrass, wild oats, quinoa, bluegrass and other weeds. The effect is poor

[0006] 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 spectrum of weed control and improve the control effect. So far, no herbicidal composition related to the compounding of benzobicyclone and isoproturon has been found.
