Late blight, caused by Phytophthora infestans , is one of the most important potato diseases globally, resulting in significant production losses. The pathogen is highly variable, adapting to newly developed cultivars and fungicides. In this study, several biocontrol agents and chemicals were evaluated in 2021 and 2022 seasons, for efficacy against blight disease in potato under field conditions. Treatments—applied individuall...

Groundnut ( Arachis hypogaea L.) is a multi-purpose legume serving millions of farmers and their value chain actors globally. Use of old poor-performing cultivars contributes to low yields (< 1 t/ha) of groundnut in sub-Saharan Africa including Tanzania. The objectives of this study were to determine the extent of genetic variation among diverse groundnut collections using phenotypic traits and simple sequence repeat (SSR) mar...
