Abstract

The invention relates to the field of pesticide preparations, and discloses a herbicide composition. The herbicide composition is composed of a compound (R)-2-(2-[4-(6-chloro-2-benzoxazolyloxy)phenoxy]propionamido)ethyl acetate and metamifop according to the weight ratio of (1-99):(99-1). The invention further discloses a herbicide, wherein the herbicide composition is used as the active ingredient, and the herbicide composition accounts for 1-99% of the weight of the herbicide. The effects of the herbicide composition and the preparation of the herbicide composition for preventing semen euphorbiae, Eleusine indica (L.) Gaertn, herb of Common Crabgrass and multiresistance barnyard grass are remarkably improved, the synergistic effect is achieved, the use amount of the effective ingredient is decreased, drug resistance of weed is delayed, pollution to the environment is reduced, and the herbicide composition and the preparation are safe to rice and can be widely applied to the field of agriculture.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a fenpyramid composition and its application. Background technique [0002] Fenpyramid is an aromatic oxyphenoxypropionate herbicide developed by the Korea Chemical Technology Research Institute and developed by Korea Dongbao Company. It is mainly used to control annual grass weeds such as barnyardgrass, stephenia, goosegrass, etc. , but fenpyramid has an unsatisfactory effect on the control of malignant weeds such as daughter of the paddy field and golden foxtail, and cannot control goosegrass and daughter of the daughter to the greatest extent. [0003] [0004] The compound (R)-2-(2-[4-(6-chloro-2-benzoxazolyloxy)phenoxy]propionamido)ethyl acetate is a compound reported in Chinese patent CN201510903087.8. Malicious weeds in paddy fields such as Stephania chinensis, Goosegrass, and Golden Foxtail have good biological activity and are relatively safe to rice. However, the compound...
