Resumo: ABSTRACT Verticillium wilt in eggplants is a root disease of difficult control. In this study, we report the relationship between soil water availability and the disease intensity in order to identify management strategies that are unfavourable to the pathogen and capable of reducing the disease progression and the damage caused by it. Four irrigation management strategies were compared in soil infested or not infested with Verticillium dahliae, which consisted of: irrigating when the available soil moisture was maintained at 90% (WA90%), 55% (WA55%) and 20% (WA20%) during the entire growing cycle, and kept at 20% in the vegetative stage, and at 90% in the production stage (WA20-90%). Experimental design was in randomized blocks, including eight treatments in factorial arrangement (4x2) and three replicates. The management strategy WA20-90% led to a significant reduction in the disease severity and in the extent of xylem colonization by the pathogen. The dry mass of plants in infested soil was 12% lower than that of control treatments and was higher with the irrigation strategy WA90% than with WA55% or WA20%. The strategy WA20-90% was efficient in reducing the disease with no significant reduction in dry mass.
