THE FUNGICIDAL ACTIVITY OF SOME PHENOXYACETIC ACID HYDRAZIDES WITH RESPECT TO ROOT ROT AGENTS

Abstract

The fungicidal activity of some phenoxyacetic acid hydrazides with respect to Fusarium oxysporum v. arth., F. sporotrichiella var. poae è F. graminearum was studied. The sensitivity of deuteromycetes that caused root rots to the substance ac- tion depended on the compound concentration and microorganism strain. The most active compound was derivative III (quinoxalin-hydrazide of phenoxyacetic acid) that inhibited F. sporotrichiella var. poae growth in 2-3 times.
