Abstract
A series of pyrazolyl-heterocycles, including 1,3,4-thiodiazoles, 1,3,4-oxa diazoles and 1,3,4-triazores were synthesized from 4-nitro-pyrazole formhyd razide. The structures of air new compounds were confirmed by H-1 NMR and e lementary analysis. Their fungicidal activity was evaluated against Rhizoct onia solani. Structure-activity relationships for the screened compounds we re evaluated and discussed. It was found that same compounds showed a highe r fungicidal activity and systematic activity.
