Hexaconazole and difenoconazole have a strong effect on radial and germ tube growth of the Fusarium sp. biocontrol agent across the all tested concentrations. The active ingredients (vinchlozolin, bupirimate, pyrimethanil) and the mixtures of cymoxanil + mancozeb and diethofencarb + carbendazim have little or moderate effect in vitro. Fusarium sp. strain was still efficient to protect the pruning wounds against B. cinerea and survived well on the plants treated with these active ingredients. This biological Fusarium sp. strain could be used in alternation or in combination with these fungicides in an integrated management of grey mold and fungal diseases in tomatoes greenhouse
