Problems solved by technology

[0007] At present, herbicides such as quizalofop-p-p, fluazifop-p-p and high-efficiency fluoxyfop-p-p are only used to control gramineous weeds in pepper fields, but they can be used to control sedges and broad-leaved weeds after emergence. There are very few herbicides, and it is urgent to develop herbicide compositions that can be used to control broad-leaved weeds and sedge weeds after transplanting in pepper fields

Abstract

The invention discloses a herbicide for capsicum annuum field. The herbicide contains two main effective components: halosulfuron-methyl and bentazone in a weight part ratio of (1-3): (40-90). Mixed use of the effective components halosulfuron-methyl and bentazone involved in the invention can reach a synergistic effect. The herbicide can prevent and control capsicum annuum field nutgrass flatsedge and broadleaf weed, has the characteristics of high herbicidal activity, wide herbicidal spectrum, significant synergy, and high safety level to capsicum annuum seedlings, thus being an ideal capsicum annuum field herbicide.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicide used in pepper fields and its application. Background technique [0002] Capsicum (Capsicum annuum L.), belonging to Solanaceae, Capsicum genus, is an annual or limited perennial herb. Weeds in pepper fields compete with peppers for water, light, fertilizer and other resources, seriously affecting the yield and quality of peppers, and becoming a constraint on pepper production. Grass weeds that are more harmful to pepper fields include crabgrass, barnyardgrass, goosegrass, and foxtail; Shepherd's purse, water chestnut, thornless mandala, sunflower, Polygonum, etc. Cyperaceae have malignant weeds such as Cyperus cyperus. Chemical weeding is the most economical and effective means of weed control. Pepper field grass weeds can be used Although quizalofop-p-p, oxaprop-p-p-p, etc., soil treatment with herbicides has played a certain role in the control of weeds in pe...
