The article is devoted to studying the efficiency of growth-regulating chemicals and biological fungi-cidal agents against early blight and late blight of potato. It was established that usage of growth-regulating chemicals decreases evolution of pathogenic agents on breeds with different tolerance to early blight by 8,3 – 47,0%, to late blight by 3,0 – 55,7%; using agrochemicals – by 6,5 – 23,0% for early blight and 1,5 – 25,3% for late blight; biological preparations – by 7,7 – 35,1% for early blight and 3,5 – 33,5% for late blight. On the basis of the completed study it was revealed that the most effi-cient agrochemicals were Akrobat MTs, Antrakol 70 WP; while among biological preparations it was Fitosporyn-M, and among growth-regulating chemicals it was Gumisol.
Key words: early blight, late blight, evolution, potato, breed, growth-regulating chemicals, fungicidal agents, biological preparations.
