摘要:
A pyrazolyl acrylic acid derivative of formula (I):
wherein R₁ and R₂ are independently hydrogen or C₁-C₅ alkyl; W is C₁-C₄ alkylene optionally substituted by C₁-C₄ alkyl, C₂-C₄ alkenylene optionally substituted by C₁-C₄ alkyl, C₂-C₄ alkynylene, -O-, -S-, or -NH-; q is 0 or 1; A is optionally substituted C₃-C₇ cycloalkyl, optionally substituted C₆-C₁₂ aryl, or optionally substiteted heteroaryl having one to three heteroatoms selected from oxygen, sulfur, and nitrogen, and having two to thirteen carbon atoms in total. Process for preparing the derivative of formula (I) and agricultural/horticultural fungicide formulation containing the derivative are also provided.
