Upon favorable moist and warm conditions, conidia (the primary inoculum) are released from lesions of an infected corn plant and carried to nearby plants via wind or splashing rain. In Central and Southern Europe the disease mostly occurs in individual years and in restricted areas (as in Austria 1995). ", Schenck, N. C., and T. J. Stelter. Suggs. The pathogen can infect different parts of the plant at several growth stages. Northern corn leaf blight is a foliar disease of corn caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria turcica. The occurrence of any specific disease depends on environmental conditions, cultural practices and the hybrid that is grown.  The fungicides should be applied to plants infected by SCLB immediately once lesions become apparent.  The fungus overwinters in the corn debris as mycelium and spores, waiting once again for these favorable spring conditions. In the early 1960s, seed corn companies began to use male sterile cytoplasm so that they could eliminate the previous need for hand detassling to save both money and time. For this reason the disease was formerly known as Helminthosporium-leaf blight. Under these conditions, spores germinate and penetrate the plant in 6 hours. Northern corn leaf blight (NCLB), caused by the fungus Exserohilum turcicum, is an increasingly important disease in the U.S. Corn Belt. The patches converge and can reach a size of up to 20 cm long and 5 cm wide. The major control measure for this maize disease also is ploughing under of straw. The objectives of this study were to evaluate the resistance of maize inbred lines to anthracnose leaf blight (Colletotrichum graminicola Ces. 1. Since then, the occurrence of the disease has been recorded in Sierra Leone, Phillippines, Ivory Coast, Malaysia, Japan, Bhutan, Burma, Indonesia Nepal, Pakistan, Southern China and Vietnam and Arkansas, U.S.A. BLSB is one of the important diseases of maize in south and Southeast Asia. Northern Corn Leaf Blight. (yellow leaf blight of maize) Toolbox. Northern corn leaf blight (NCLB) is a common leaf disease and occurs in all maize growing areas of the world. NCLB score and lesion size were investigated after artificial inoculation. The southern corn (Zea mays L.) leaf blight (SCLB) epidemic of 1970–1971 was one of the most costly disease outbreaks to affect North American agriculture, destroying 15% of the crop Exserohilum turcicum). Severe leaf blight and defolia tion of beans by A. Southern corn leaf blight is considered the most devastating disease of maize crop, which causes noticeable reduction in crop yield. Drechs. Turcicum leaf blight of maize caused by the fungus Setosphaeria turcica is a serious foliar disease of maize distributed widely throughout the world and causing significant yield losses. Datasheet. Leaf blight of maize Economically relevant diseases in maize occur more and more in all warmer maize growing areas in Germany since the middle of the nineties. For example, it is important to manage crop debris between growing seasons, as B. maydis overwinters in the leaf and sheath debris. It is also known as southern corn leaf blight (SCLB). Thus big parts of the leaf blade can die back but rarely the whole leaf does. Banded leaf and sheath blight of maize is also known as sharp eye spot, oriental leaf and sheath blight, Rhizoctonia ear rot, sheath rot and corn sheath blight etc (Rijal et al., 2007). Several streaks may develop on leaf and may extend on the entire leaf. The asexual cycle is known to occur in nature and is of primary concern. , Because symptoms are a plant response and similar ones can be seen with other plant pathogens, Bipolaris maydis infection can be confirmed microscopically.  The generation time for new inoculum is only 51 hours. Grey leaf spot (GLS) is a foliar fungal disease that affects maize, also known as corn.GLS is considered one of the most significant yield-limiting diseases of corn worldwide.
