In vivo Studies on the Effect of Warburgia ugandensis Crude Extracts Against Bacterial wilt in Tomato

Asian Journal of Agricultural and Horticultural Research
Tomato plants are susceptible to Ralstonia solanacearum, a pathogen responsible for bacterial wilt, a severe soil-borne disease with no available cure. Warburgia ugandensis crude extract has shown biocontrol capabilities against pathogenic fungi and bacteria in animals, but data on its effectiveness in plants is limited.
