Abstract: The fungi Macrophomina phaseolina is the charcoal rot causal agent, one of the most important cowpea crop disease in semiarid regions can causes 100% yield losses. The search for resistant genotypes requires efficient phenotyping. In addition, there is the problem of great variation in aggressiveness between isolates. This study aimed to 1) test three methods of inoculation in semiarid conditions, and 2) to evaluate the aggressiveness of isolates of M. phaseolina. In the first experiment carried out in greenho… Show more

“…Based on the GAA, the aggressiveness of the M. phaseolina isolates, ISO16 and CMM2684 agreed with the observations by Souza et al. (2021) in a study where these isolates were inoculated using different methods. The low virulence of isolate CMM2684 compared to the others may be related to its host of origin.…”

“…The high incidence rate proves the efficiency of the inoculation method with stem drilling with a toothpick to quickly, reliably and reproducibly assess resistance to charcoal rot in cowpea plants (Souza et al., 2021; You et al., 2011).…”
