Chávez-Calvillo, G.; Contreras-Paredes, C.A. ; Peterson, D.A. Given that the observational and sampling component of the current study were limited in scope, we propose further studies to expand these aspects in order to assess the seasonal variations of the epidemics, the role of the interaction among multiple viruses on severity of MLN, how the genetic variability of SCMV affects MLN, and the role of vectors in respect to changes in the climatic factors.

A simple random sampling technique was used to obtain a sample of 172 respondents from a target household population of 10,000 maize farmers. Maize lethal necrosis (MLN) is a major disease in sub-Saharan Africa (SSA) caused by co-infections of maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) [].MCMV can able to interact with any member of the Potyviridae family to cause lethal necrosis in maize [].Yield loss due to MLN can reach up to 100% under severe infection and MLN favorable environments [1,3]. ; Formal analysis, F.H.K., S.M. ; Rees, D.J.G. regions with small to medium effects. ; Van Der Walt, E.; Dent, K.; Varsani, A.; Rybicki, E.P.
