All-Russia Research Institute of Oil Crops "V.S. Pustovoit" (VNIIMK), Filatova 17, 350038, Krasnodar, Russia Received: October 15, 2006 Accepted: December 05, 2006 SUMMARY Fusarium fungi have grown from a minor pathogen of sunflower crop to a major problem of sunflowers in Russia. The aim of this work was breeding for resistance to this new major pathogen, combining field and laboratory testing in the

Introduction Due to their

was necessary to develop effective nematicides with low risk for humans and wildlife, we have focused our atten- tion on new nematicides from fungal metabolites that are valuable natural sources for agrochemical development, and we found the presence of the regulators in the mycelia of Fusarium bulbicola (Fotso et al., 2002). Our investigation on metabo- lites of this fungus has now led to the isolation of one active substance, beauvericin (1) (Hamill et al., 1969). The present paper describes the pro- duction, isolation, structural determination, and
