What is cassava leaf blight and its causes. The leaf Blight of cassava disease is the disease of the cassava caused by a bacterium known as xanthomonas manibotis.
Unlike the cassava mosaic disease the leaf Blight of cassava is caused by a bacteria which affect the cuttings through rain splashing etc.
manihotis is the pathogen that causes bacterial blight of cassava discovered in Brazil in 1912,
the disease has spread through cultivation of cassava across the world. Among diseases which affects cassava all over world, bacterial blight causes the largest damages in terms of yield and production.
How the leaf blight disease of cassava is transmitted
The cassava Leaf blight disease is transmitted through infected cuttings, leaves of wilting plant, Rain splashing, insects and the use of tools like simple Farm tools during weeding
If one cassava plant is infected, the whole crop is put at risk of infection through rains plash, contaminated cultivation tools, and foot movement. These are effective methods of transmission because they cause bruises to healthy cassava crops, and the bacteria uses these wounds as an entry point.
