Abstract: Maize (Zea mays L.) is one of the important cereal crop of the world. It belongs to family Poaceae and ranking the world?s third cereal crop after wheat and rice. It is also consider as queen of the cereal. Maize grains are widely used for human consumption; poultry feed livestock, edible oil extraction and also helpful in starch and glucose production industry. Yield of maize was reduced as much 86 percent when weeds were not controlled in maize cultivation in our countries. Maize (Zea mays L.) also called as corn. It became a staple food in many parts of the world. Production of maize being reduces due to one of the important disease that is TLB caused by Exserohilum turcicum. The infected maize plants exhibits typical symptoms of long spindle shaped necrotic lesions with grey colour centre, immature and chaffy ears. The turcicum leaf blight disease reduces the green chlorophyll area of plant which manufactures food for the plant. If considerable leaf area reduces results in loss of the vigour, restrict formation of starch which results in chaffy kernels and ultimately reduces the yield. TLB disease directly affected by many abiotic factors. The finding of this paper reveals that abiotic factors such as temperature, humidity, rainfall and wind are beeline helpful in the spread of TLB in maize. Maximum disease severity was noticed in the months of June and July when temperature ranges about (25-30oC), humidity (75-90%). and rainfall 46 mm. When these parameters fluctuate, temperature more than 30oC, humidity 75% than the severity of disease become low. This present finding reveals the positive and negative correlation of disease in maize.
