METHOD FOR PRELIMINARY ASSESSMENT OF EFFICIENCY OF DESCENT OF SMUT INJURIOUSNESS BY PHYTOEXTRACT ON GRAIN CROPS

摘要

A method for preliminary assessment of efficiency of descent of smut injuriousness by phytoextract on grain crops involves separation of phytoextract to fractions, bioassay of phytoextract and components thereof, calculation of correlation and path coefficient, determination of efficiency index.
