Mancha areolada causada por Thanatephorus cucumeris em mogno africano [PDF]

Fitopatologia Brasileira, 2001
O mogno africano (Khaya ivorensis) foi introduzido no Brasil para substituir o mogno brasileiro (Swietenia macrophylla) devido a sua alta resistência ao microlepidóptero Hypsiphyla grandella, a principal praga do mogno brasileiro. Em 1999, observou-se alta incidência da mancha areolada, causada por Thanatephorus cucumeris em viveiros e áreas de ...

The Mechanism of Host Penetration by Thanatephorus Cucumeris [PDF]

Australian Journal of Biological Sciences, 1963
Evidence is presented in support of the hypothesis that chemical stimuli control the development of infection structures on the host surface by T. cucumeris. On the stem of a young radish seedling there are discrete, susceptible a·reas which become fewer and eventually disappear as the seedling ages.

A sick plot–based protocol for dry root rot disease assessment in field‐grown chickpea plants

Applications in Plant Sciences, Volume 9, Issue 8, August 2021., 2021
Abstract Premise A comprehensive field‐based screening protocol is lacking for dry root rot (DRR) disease in chickpea, which is caused by Macrophomina phaseolina (formerly referred to as Rhizoctonia bataticola). Here, we describe a protocol for establishing a sick plot for DRR to enable disease assessment of a large number of chickpea plants during the
