In vitro and in vivo toxicity of fungicides and biofungicides for the control of verticillium and fusarium wilt of pepper

A survey of in vitro and vivo sensitivity Verticillium dahliae Fusarium oxysporum to several commercial fungicides biofungicides was undertaken. In assays, the tested isolate V. proved be very sensitive difenoconazole (EC50 = 0.02 mg/l). However, under greenhouse conditions, highest efficacy control on inoculated pepper plants recorded for a product based thiophanate-methyl (83.10% compared control). Among fungicides, lowest azoxystrobin (23.10 %) with no significant difference (p > 0.05). F. most prochloraz 0.07 mg/l) least fluopyram 1075.01 assay, achieved by products captan (95.60%), (54.40%). Antagonistic activity bacterium B. subtilis laboratory conditions not satisfying. Also, antifungal spectrum tee tree oil efficient suppressing wilting caused oxysporum.
