| Resumo: | The pattern of diseases produced by phytopathogens in some areas of cultivation are changing drastically due, among other causes, to new market trends that induce changes in the agricultural practices, and the introduction of new crops. Monitoring these changes is important in order to take appropriate and timely actions to prevent disease dispersal. A dramatic difference was observed between fungal diseases and one probable bacterial disease of Agave fourcroydes. Anthracnose leaf spot was present in 1.6% out of the total plants monitored throughout the year at Telchac Pueblo, Yobain and Dzidzantunall, state of Yucatan, Mexico; while pole dry rot and apex dry rot were in 2.5 and 1.2% respectively. In contrast, leaf dry tip (LDT) was detected in all the plantations studied, affecting 42% of the total plants at all locations. LDT also affects fibre yield severely and it is therefore the most serious disease in the area. In this paper, we report the phytopathological status of henequen plantations in the state of Yucatan and discuss the serious threat to productivity posed by the high incidence of LDT disease. |
