By: H. Shew*

topics (OpenAlex): Plant Disease Management Techniques; Plant Pathogens and Resistance; Plant Pathogens and Fungal Diseases
TL;DR: Cultivars of burley tobacco with different levels of resistance to Thielaviopsis basicola were planted in fields naturally infested with the pathogen and the severity of root rot and the reproduction of T. basicola was determined at transplant, midseason, and after final harvest.
