FIELD: organic chemistry, herbicides, agriculture.
SUBSTANCE: invention describes benzoylpyrazoles of the general formula (I):
wherein A means alkylene; R1 means alkyl; R2 means hydrogen atom, alkyl; R3 means hydrogen atom, alkyl, halogen atom, alkylsulfonyl, alkoxyl; R4 means nitro-group, halogen atom, alkyl; Y means hydrogen atom, alkyl, alkylsulfonyl, alkenyl, phenylsulfonyl, phenylalkyl; Z means substituted 5-6-membered saturated or unsaturated heterocyclic group. Invention describes agent based on compound of the formula (I). Proposed benzoylpyrazoles elicit strong herbicide activity and broad spectrum of effect both in treatment of soil and in treatment of above-ground parts of plants.
EFFECT: valuable properties of compounds.
