Why and where it occurs
Sheath blight occurs in areas with high temperature (28-32 ° C), high levels of nitrogen fertilizer, and
relaljve humidity of crop canopy from 85-100%.
Plants are more vulnerable to sheath blight during the rainy season.
High seeding rate or close plant spacing, dense canopy, disease in the soil, sclerotia or infection bodies
Roating on the wateR and growing of high yielding improved varieties also favor disease development.
