Abstract

The invention relates to a herbicide composition for carrot land. The herbicide composition is mainly composed of active ingredients including quizalofop-p-ethyl and prometryn according to a mass ratio of 1:2-20. The herbicide composition can prevent and remove gramineous weed and broad-leaf weed, and is high in weeding activity, wide in weeding spectrum and remarkable in effect improvement; the herbicide composition is high in safety grade to carrot seedlings and is an ideal post-seedling herbicide of the carrot land.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicide composition containing quizalofop-p-sperm and prometon, which is applied to post-emergence weeding in carrot fields. Background technique [0002] Carrot is a biennial herbaceous plant of the genus Carrot in the Umbelliferae family. Its fleshy roots are rich in carotene, various amino acids and vitamins. It is an important vegetable crop with extremely high economic value. Weeds in carrot fields compete with carrots for water, light, fertilizer and other resources, seriously affecting the yield and quality of carrots, and becoming an important threat to restrict carrot production. Grass weeds that are more harmful in carrot fields include crabgrass, barnyardgrass, goosegrass, and foxtail, and broad-leaved weeds include horse cucumber, velvetleaf, snakehead sausage, and purslane. Chemical weed control is the most cost-effective means of weed control. Carrot fiel...
