A shift towards organic farming suggests amalgamation of organic resources against soil borne plant pathogens. The influence of metabolites of most ubiquitous Aspergillus spp., organic amendment extracts and their combined effect with Trichoderma virens were evaluated in vitro against Rhizoctonia solani. The minimum (36.1 mm) growth was attained by R. solani in co-culture with A. niger. The maximum (42.3 mm) inhibition of mycelial growth of the test organism was observed with culture filtrate of A. ochraceous followed by A. niger, A. fumigatus, A. flavus and A. terreus. Among organic amendment extractants, castor cake exhibited an additive effect on the growth of T. virens, however, the maximum (41.8 mm) suppressive effect on R. solani was observed with vermicompost. With the advance in time, the effect of organic amendment extracts increased markedly. Inhibition potential of culture filtrate mixturte of A. niger + T. virens and A. ochraceous + T. virens against R. solani was significantly higher in comparison to the other combinations.

W produkcji ekologicznej sugeruje się połączenie organicznych źródeł przeciwko patogenom odglebowym. Oceniono wpływ metabolitów powszechnie występujących gatunków Aspergillus, organicznych wyciągów i ich łączne działanie z Trichoderma, przeciwko Rhizoctonia solani. Najmniejszy wzrost (36,1 mm) R. solani odnotowano w podwójnej kulturze z A. niger. Maksymalną inhibicję (42,3 mm) wzrostu grzybni testowego mikroorganizmu zaobserwowano w przypadku filtratu kultury z A. ochraceous, a następnie z A. niger, A. fumigatus, A. flavus i A. terreus. Spośród wyciągów, te z rącznika wykazywały stymulujące działanie na wzrost T. virens, a maksymalne (41,8 mm) supresyjne działanie na R. solani obserwowano w przypadku wermikompostu. Z czasem, działanie wyciągów z organicznych dodatków znacznie wzrastało. Potencjał inhibicyjny mieszaniny filtratu kultury A. niger + T. virens i A. ochraceous + T. virens przeciwko R. solani był istotnie wyższy w porównaniu z innymi kombinacjami.
