Generally speaking the later the infection starts the lower are the yield losses. This disease is often found in Central Europe, but cost-effective damages have not been caused yet. Banded leaf and sheath blight disease caused by Rhizoctonia solani f. sp.  Avoid late planting in prevalent areas. We use cookies to ensure that we give you the best experience on our website. Lesions begin on the lower leaves and then spread to upper leaves. Northern corn leaf blight (NCLB) also known as Turcicum leaf blight of maize is major foliar disease and it’s a problematic to maize farmers in highland of Himalayan region, worldwide. Distinct patches of infection on maize are rarely to be observed in our region before inflorescence emergence. 3) Charcoal rot. In the past the anamorph (production of asexual spores called conidia) of the pathogen was named Helminthosporium turcicum. (yellow leaf blight of maize) Toolbox. Material and Methods Field experiment was conducted during kharif 2017 and 2018 in Maize Agronomy block at Norman E. Borlaug Crop Under these terms infestations developed in France. it is important to control diseases of maize which are mention below as it causes yield losses. If the infection takes place 5-6 weeks after flowering yield reduction is marginal. B. Fusca is perhaps the most widespread noctuid in the African region south of the Sahara. Insect pests of maize include stem borers- Busseola Fusca and Sesamia calamistis. Epidemiology and Management of Turcicum leaf Blight of Maize Caused by Exserohilum turcicum (Pass.) ... STUBBLE MANAGEMENT AND CROP INSPECTIONS. Wide host range of pathogen, its ability to survive as sclerotia under adverse environmental conditions and lack of resistant sources are some of the bottlenecks in its management. Storage insects can be controlled by fumigating stores with insecticides e.g aluminum phosphide or one tablet of fumigant per two bags of maize. Corpus ID: 90465309. KwaZulu-Natal and Mpumalanga, it is common and causes serious yield Under these terms infestations developed in France. Most of the important diseases of maize are foliar and the more common ones are rusts, leaf blights, leaf spots, brown spots, downy mildew, and maize streak virus (MSV). The lesions are initially bordered by gray-green margins. It initially infects the maturing crop in the field and builds up and causes serious damage in the store. First symptoms on maize plants appear on the lower leaves. sasakii Exner. MAIZE LEAF BLIGHTS. However infested plant residues are the origin of infection for following years. Thus big parts of the leaf blade can die back but rarely the whole leaf does. In the USA it occurs mainly in the northern Corn Belt. Sitophilus zeamais, the maize in the tropics. The first signs are tiny yellowish spots on the leaves which eventually turn brown. The more common one in some parts of Africa is caused by the fungus Helminthosporium maydis. Benefits of Minerals to Pigs and their Deficiency symptoms, Antibiotics in Pig Production - Benefits and Concerns, Rice Diseases and How to Prevent/Control it for Higher Yield Advantage. The most feasible means of control is by planting resistant varieties. They eventually turn tan colored and may contain dark areas of fungal sporulation. Today the conidia stage is classified as Exserohilum turcicum.  Crop rotation so that invasion by infected Cicadulina is limited. BLSB has become an increasingly severe and economically important disease which occurs in moderate to severe intensities in several countries every year (Sharma et al., 2002). Key words: Northern leaf blight, Exerohillum turcicum, Genotypes, Severity, Resistance. On this substance conidia and chlamydospores (asexually produced spores from mycelium) are formed which are distributed to the lower maize leaves by rain splashes. Mycosphaerella zeae-maydis (yellow leaf blight of maize) Index. Fig.2 Typical cigar shaped lesion of turcum leaf blight on maize leaf Fig.3 Disease cycle of turcicum leaf blight of maize Int.J.Curr.Microbiol.App.Sci (2017) 6 (3): 825-831 Downy mildew is a very serious fungal disease of maize caused by Peronosderospora sorghii. mays) known in many countries as corn or mielie/mealie, is a grain domesticated by indigenous peoples in Mesoamerica in prehistoric time The leafy stalk produces ears which contain seeds called kernels.Though technically a grain, maize kernels are used in cooking as a vegetable or starch. CORRELATES OF STUDIES ON HELMINTHOSPORIUM BLIGHT OF MAIZE WITH SPECIAL REFERENCE TO MANAGEMENT FOR ODISHA CON DITION S. DASH 1, S. BEHERA 2 & B. S. BEHERA 3 1Research Scholar, College of Agriculture, Bhubaneswar, Odisha, India 2AAO, Thuamul Rampur, Odisha, India 3Research Scholar, OUAT, Bhubaneswar, Odisha, India ABSTRACT Maize rust (Puccinia sorghi) is widespread especially in tropical and subtropical areas. When infection occurs prior to and at silking and conditions are optimum, it may cause significant economic damage. The major control measure for this maize disease also is ploughing under of straw. The diseases can be controlled with fungicidal sprays, e.g. Apron plus or Ridomil at 2g/kg of seed. CONTROL crop rotation, intercropping, and the use of trap crops.
