The effect of flax seed dressing with biopreparations, chitosan, and its derivatives on fungal communities in soil was evaluated. Biopreparation organisms consisted of: Pseudomonas aureofaciens, P. fluorescens, Pythium oligandrum, a mixture of photosynthetic and Lactobacillus bacteria, and unidentified yeasts and fungi. Chitosan and its derivative active ingredients were used: chitosan microcrystalline,...
The study was aimed at evaluation of resistance of breeding lines of fibrous and oil flax to Fusarium wilt. The studies were conducted under provocation conditions in field experiments. According to the results of long term research the crossings that showed the highest resistance to Fusarium were selected. These were the following genotypes: Nike, Natasja, Viking, Laura, Orszanski 2 , Marina, Ariane,...
Opracowywano formulacje doświadczalne biopreparatów na bazie surowców roślinnych do stosowania w ekologicznych metodach ochrony lnu przed chorobami: olejek konopny, wyciągi z czosnku, tymianku, oregano, arcydzięgiela oraz z cynamonu. W doświadczeniach laboratoryjnych i wazonowych oceniano wpływ tych środków na zahamowanie rozwoju kultur Fusarium oxysporium f. sp.lini, oraz na zdrowotność i zdolność...
W Instytucie Włókien Naturalnych w Poznaniu w doświadczeniach polowych, przez trzy lata badano wpływ wybranych biopreparatów i substancji na ograniczenie występowania fuzariozy lnu włóknistego. Testowano jako zaprawy do nasion biopreparaty, takie jak Polyversum, którego czynnikiem aktywnym jest Pythium oligandrum, Cedomon i PSR 21 zawierające bakterie z rodzaju Pseudomonas oraz substancje oparte na...
