Guide to plant virus diagnosis
These guides summarize all basic information on particular emerging and important virus diseases and offer instructions for a safe and reliable detection of the species being involved. Please click on the image to download the DSMZ Guide to Plant Virus Diagnosis as pdf.
Our first guide deales with maize lethal necrosis (MLN), a serious emerging disease of maize in East Africa. The MLN disease (syn. corn lethal necrosis, CLN) is known to naturally affect varieties of maize (Zea mays) resulting in chlorotic mottling of the leaves, severe stunting and necrosis, often leading to plant death. MLN is caused by a mixed infection between Maize chlorotic mottle virus (MCMV, genus Machlomovirus) and potyviruses infecting maize. In Kenya and other countries, most frequently Sugarcane mosaic virus (SCMV). DSMZ offers ELISA and lateral flow assays for a reliable and fast detection of both species.
