Herbicide composition for paddy fields containing a number of Derivatives of tricetona Component effective herbicide,Tricetona derivative and method of weed control in Rice Paddy herbicide using Said composition

摘要

Herbicidal compositions for paddy fields containing a quantity of tricetona derivatives as effective Component tricetona derivative and herbicide; weed control method used in paddy fieldsWhen the herbicide composition, the tricetona derivative represented by the following formula (1) and salts thereof, where Y1, y2, y3, R1, R2, P,R3 and R4 are as follows: Y1 represents a c1-4 alkyl Halogen; c1-4 haloalquilo; c1-4 alkoxy; c1-4 Alquiltio; c1-4 alquilsulfonilo; c1-4 alquilamino; (c1-4 alkyl amido); Nitro, amino, Hydroxy,Mercapto or cyano; y2 represents Hydrogen or Halogen, c1-4 alkyl; Y3 represents Hydrogen or alkyl of C1 - 6; n represents 1 or 2; P represents 0 OR 1, R1, R2, R3,And R each independently represents Hydrogen, c1-4 alkyl or phenyl,Being either R1 or R2 R3 or R4 together to form a double Bond in the Molecule when p = 1 and x represents an oxygen Atoms of group or a group represented by the formula (2) 'And R5 and R6 each independently represent Hydrogen, c1-4 alkyl or phenyl. The Method for the control of weeds in rice fields used herbicide composition.Tricetona derivatives and compositions are less aggressive herbicides for Rice Paddy Field and have a broad spectrum of weed control with small dose of Paddy FieldApplication.
