Chemical and biological control of Fusarium species involved in garlic dry rot at early crop stages

Abstract The aim of the study was to test in vitro and vivo efficacy triazoles biocontrol agents (BCAs) against Fusarium proliferatum F. oxysporum , former signaled as main causal agent garlic dry rot latter also involved. In trials were organized using potato dextrose agar with added chemicals or BCAs inoculated selected . Garlic cloves dipped before sowing suspensions prepared fungicides showing best performances vitro; then they Fusaria suspension sowing. trials, maximum growth inhibition performed by Propiconazole + Prochloraz (100%), followed Tebuconazole (88.9%). showed great capacity control Fusaria, a 80% ( Trichoderma harzianum T. gamsii ) bacterial similar compared chemical products (mean severity index 18.6% 11.7%, respectively). results confirmed performances, except for which had worst vivo. Therefore, are preliminary but promising future field application.
