THE USE OF BIOSEPT 33 SL, BIOCHIKOL 020 PC AND POLYVERSUM TO CONTROL SOYBEAN (Glycine max (L.) Merrill) DISEASES AGAINST PATHOGENS. PART I. HEALTHINESS AND YIELDING OF SOYBEAN AFTER USING BIOPREPARATIONS

Abstract

The object of the studies were soybean plants grown of the seeds dressed with Polyversum, Biochikol 020 PC and Biosept 33 SL. At anthesis those plants were sprayed with the same biopreparations. The experiment considered a combination with the chemical preparation Zaprawa Oxafun T for seed dressing, and Bravo Plus SC for spraying plants at anthesis. It can be stated on the basis of the obtained results that the application of biopreparations for seed dressing and spraying plants at anthesis was similar to that of chemical preparations. Among the studied biopreparations, Biosept 33 SL turned out to be the most effective in protecting plants from soil-borne pathogenic fungi.
