Abstract

The invention relates to a synergic weed killing composition which jointly comprises fluroxypyr and fluoroglycofen ethyl as effective ingredients and acceptable auxiliary ingredients in pesticide, wherein the weight ratio of fluroxypyr to fluoroglycofen ethyl is 32:1-1:2. The two effective ingredients in the composition has obvious synergism, the weed killing spectrum is enlarged, various broad-leaved weeds can be prevented and killed, the quick acting effect of the composition is better than that of fluroxypyr, and the production cost is reduced.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition used in wheat fields, paddy fields and corn fields. Background technique [0002] Fluroxypyr has a chemical structure as shown in formula (I). Fluroxypyr is a pyridyloxyacetic acid herbicide. It is a selective, systemic, post-emergence stem and leaf treatment agent. It is produced by weeds Stems and leaves absorb. The pesticide is quickly absorbed by the weeds after application, and the sensitive weeds will respond to typical hormone herbicides, and the plants will be deformed, twisted, and eventually die. It can effectively control a variety of annual and perennial broad-leaved weeds, and is suitable for the control of various broad-leaved weeds in wheat, barley, corn, rice (seeding field, direct seeding field, throwing seedling field, transplanting field, border), orchard, etc. ; such as bermudagrass, water peanuts, sagittarius, pig scorpion, Polygonum curc...
