INTEGRATED MANAGEMENT SYSTEM FOR PINEAPPLE FUSARIUM DISEASE CONTROL

J.A. Ventura, L. Zambolim, G.M. Chaves
The pineapple (Ananas comosus (L.) Merr.) Fusarium disease caused by Fusarium subglutinans is the most important problem of this crop in Brazil. Fruit losses reach 30–40% and losses in propagative material (slips and suckers) reaches 20%. The most important control measures are to plant disease-free propagative material and to protect inflorescences by spraying with fungicides. Pathogen-free plant material can be obtained through a rapid propagative technique by sectioning the plant stumps after harvesting. To obtain low fruit disease severity the following control measures are recommended: a) induce flowering of plants in months with low rainfall; b) protect the inflorescences of induced plants with benomyl at 0.05% or captafol 0.15% a.i.; c) protect inflorescences with paper bags or suppress flower opening with ethephon, which may not be economically feasible. Recently, research has been carried out to obtain resistant cultivars to the pathogen, opening a new approach to integrated control of the disease.
