Evaluation of Fungicides for Control of Fusarium Wilt of Potato

Abstract:
Four fungicides, which active ingredients are hymexazol, azoxystrobin, fludioxonil and quinoline, are tested in vitro and in vivo against five isolates of Fusarium oxysporum f. sp. tuberosi, causal agent of potato Fusarium wilt. Pathogen radial growth noted on PDA amended with fungicides after incubation for four days at 25°C varied upon pathogen isolates. Mycelial growth of all pathogen isolates was significantly inhibited by fungicide PDA amendment; inhibition obtained by hymexazol treatment reached 77% comparatively to untreated control. All chemical fungicides reduced disease incidence compared to the untreated control. Hymexazol and azoxystrobin are the most active during all the bioassay period. Whereas, fludioxonil and quinoline showed a limited effect in controlling Fusarium wilt development.
