Viral synergism and its role in management of maize lethal necrosis disease
Maize lethal necrosis disease (MLND) in Kenya has been reported to be caused by a coinfection between a non-potyvirus Maize chlorotic mottle virus (MCMV) and a potyvirus Sugarcane mosaic virus (SCMV). The control of the disease in Kenya has been a challenge owing to the synergistic interactions that exist between the two viruses. This study, sought to determine the stage of synergism between the two viruses and its role...
