Name: Substituted phenyl five-membered nitrogen heterocyclic herbicide publication number: 1402979
Application No.1
Applicant: Wang Zhengquan Abstract The present invention provides a herbicide having a structure substituted with a phenyl five-membered aza-pyrazole or an isoxazole structure, that is, on the phenyl ring, the nitrogen ring at the 1-position is a pyrazole or a heterosexual The azole derivative, the hydrogen atom of the 2, 4-position carbon atom is substituted by a fluorine atom or a chlorine atom, respectively, and a different substituent is bonded to the 5-position. The melting points of the synthesized compounds were determined, respectively, and the structures thereof were confirmed by MS and H-NMR. Herbicide on grass weeds,
The herbicidal activity test of foxtail and broadleaf ramie and leeks has achieved good results.
