Influence of Internal Seedborne Fusarium semitectum on Cotton Seedlings
Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton (Gossypium hirsutum) seed lots. There was no correlation, however, between its incidence and seedling emergence and disease symptoms on the emerged seedlings in autoclaved sand. Inoculation technique simulating internally seedborne nature of the fungus showed that the observed non-correla...

متن کاملA Semi-Selective Agar Medium to Detect the Presence of Xanthomonas axonopodis pv. malvacearum in Naturally Infected Cotton Seed
A semi-selective agar medium was developed for detection of Xanthomonas axonopodis pv. malvacearum (Xam) in cotton (Gossypium hirsutum) seed. The basic medium was peptone-sucrose-agar (PSA). Criteria for the semi-selective medium were the typical colony characters of Xam and its pathogenicity on cotton. Several systemic fungicides and antibiotics in different concentrations were tested alone or...
متن کاملEFEITO DO DESLINTAMENTO QUÍMICO SOBRE A OCORRÊNCIA E DESENVOLVIMENTO DE Colletotrichum gossypii ASSOCIADO ÀS SEMENTES DE ALGODOEIRO*
Effects of chemical delinting on the level of occurrence and development of Colletotrichum gossypii associated with cotton seeds The present work was conducted in two phases. The first phase evaluated how the lenght of time of chemical delinting, 1:30 and 4:30 min, effected the level of infection by Colletotrichum gossypii on artificially inoculated cotton (Gossypium hirsutum) seeds. Non-delint...
