Maize Lethal Necrosis Disease (MLND) - A snapshot

Maize lethal necrosis (MLND) is a combination of two viruses, one of corn chlorotic mottle virus (MCMoV) and a group of Potyviridae such as sugar cane mosaic virus (SCMV), wheat streak mosaic virus (WSMV) Results. ) Or corn atrophy mosaic virus (MDMV). Dual infection of these two viruses results in so-called MLND, also known as corn-killed necrosis (CLN).

Seed inspectors can examine corn-killed necrosis (MLND) in seed farms. Phytosanitary authorities can inspect corn chlorotic mottle virus (MCMV) for all seeds entering the country, including breeding materials. Domestic regulation can be carried out to prevent corn product from flowing from affected area to diseased area. This illness is commonly conveyed through press releases, posters, brochures, promotional workshops and radio programs. Information on diseases is commonly conveyed on the day of field study and spread to the Bazarus of the Church. Understanding the disease moves diseased plant material from one area to another by destroying affected crops, preparing a breeding environment, or practicing general field hygiene It helps to take measures to prevent.

Maize lethal necrosis (MLND) is a combination of two viruses, one of corn chlorotic mottle virus (MCMoV) and a group of Potyviridae such as sugar cane mosaic virus (SCMV), wheat streak mosaic virus (WSMV) Results. ) Or corn atrophy mosaic virus (MDMV). Dual infection of these two viruses results in so-called MLND, also known as corn-killed necrosis (CLN).

The symptoms of lethal necrosis of corn (Photo 1a and Photo 1b) are synergistic co-infections of the symptoms of corn and corn's chlorotic mottle virus (Photo 2) and viruses of Potyviridae family such as wheat streak mosaic virus, short corn It is caused by. Symptoms of mosaic virus or symptoms of sugar cane mosaic virus (original corn atrophic mosaic virus - B) (picture 3). Infections of each virus alone cause mild symptoms, but a synergistic reaction of corn mottle spot mosaic virus and arbitrary potato virus complex infection causes plant death. In many cases it is known that symptoms of fatal necrosis in maize appear only with corn chlorotic mottle virus infection under abiotic stress conditions such as drought and low nitrogen.
