چکیده

The area planted with avocado crops in Colombia has been growing rapidly recent years, especially for export varieties such as Hass. increase coincided increased phytosanitary problems, where pathogens fungi of the genus Verticillium spp. are becoming economic importance. objective this study was to evaluate different control strategies wilt disease caused by spp., under vitro, net house, and field conditions. Strategies tested included fungicides (benomyl, azoxystrobin, captan, carbendazim), beneficial antagonistic microorganisms (Trichoderma sp., Rhizoglomus fasciculatum), physical cultural practices solarization, drainage removal diseased tissues. Treatments T7fi (pruning-solarization-Trichoderma-mycorrhiza-sucrose-organic matter-drainage) T8fi (fungicide-pruning-solarization-Trichoderma-mycorrhiza-sucrose-organic matter-drainage), showed greatest reduction progress curve dahliae inoculum soil plant tissues Fruit extra quality 120.8% 108% T8fi, compared trees. highest costs were identified T8fi; however, these treatments also best cost/benefit relationship. Integrated approaches results control. As no chemical synthesis (pruning-solarisation-Trichoderma-mycorrhiza-sucrose-organic it should be preferred which does include them, avoid their negative impacts on production.
