Abstract
The fungicidal effects of the biological preparation Ketomium® comprising a Chaetomium spore suspension were evaluated for its effect on Siberian isolates of the phytopathogenic fungi Botrytis cinerea, Didymella applanata, Fusarium oxysporum and Rhizoctonia solani. Ketomium-mycofungicide inhibited the growth of the taxa in vitro; however, the degree of the inhibition depended on the fungal pathogen and the concentration of preparation used. In vitro, Ketomium-mycofungicide was most efficient at suppressing Didymella applanata which causes Raspberry Spur Blight. Field-testing of Ketomium-mycofungicide on potato yields was carried out in a potato plantation. Ketotomium-mycofungicide led to significant suppression of potato disease caused by Rhizoctonia solani. Introduction of Ketomium-mycofungicide into the soil during planting resulted in a significant potato tuber yield increase. This preparation of Ketomium-mycofungicide showed promise as a new means of biological control of plant diseases in Siberian conditions. Ketomium-mycofungicide appears to be a promising preparation with activity following a rather long period of storage and acts as a new broadspectrum mycofungicide.
