It was stated that the contact of Penicillium frequentans and P. verrucosum var. cyclopium with Globodera rostochiensis in the medium stimulated reduction in the number of cysts of nematodes. Among 16 P. verrucosum var. cyclopium metabolites the strongest destruction of eggs and larvae in G. rostochiensis cysts was observed in the case the Rr = 0.31 and Rr = 0.75 substances. The above metabolites caused that irregular lipid-like granules formed in the intestine tracts of the G. rostochiensis larvae. Most probably, the pathological presence of lipides in the intestine resulted from the distemper of synthesis of lipolythic enzymes in the nematodes under the effect of the P. verrucosum var. cyclopium extracts
