Caracterização de isolados de Rhizoctonia associados à queima foliar em Roraima.

Abstract: Resumo -O objetivo desse trabalho foi caracterizar isolados do fungo Rhizoctonia associados à queima foliar, obtidos de hospedeiros de importância econômica no estado de Roraima. Os isolados foram obtidos de plantas de feijão-caupi (Vigna unguiculata), soja (Glycine max), seringueira (Hevea brasiliensis), melancia (Citrullus lanatus), alface (Lactuca sativa) e feijão-guandu (Cajanus cajan). Os parâmetros utilizados foram números de núcleos, grupo de anastomose e as características culturais da colônia, taxa de… Show more

“…Similarly, copper oxychloride, another broad-spectrum fungicide, inhibited sclerotia production (Ferro et al, 2019). The inhibition of sclerotia production under fungicide stress occurred due to the resulting lower fungal mycelia growth, as large amounts of mycelium are required for sclerotia production (Youssef et al, 2012).…”
