Introduction: Maize (Zea mays) is one of the most important cereal crops. It is ranked as 3rd after wheat and rice. Due to its wide adaptability, diversified uses, and low production costs, it has great potential as a cereal crop. In the case of yield losses, various factors are involved. The fungal diseases of maize play a significant role in the reduction of both quantity as well as the quality of maize. Review Results: At the seedling stage, maize suffers from numerous diseases and many of them are seed-borne diseases. Anthracnose stalk rot (Colletotrichum graminicola), Charcoal rot of maize (Macrophomina phaseolina), Crazy top downy mildew disease (Sclerophthora macrospora), Corn grey leaf spot disease (Cercospora zeae-maydis), Aspergillus ear and kernel rot (Aspergillus flavus), Corn smut (Ustilago maydis), Southern corn leaf blight disease (Bipolaris maydis) etc. are important among these diseases.Chemical control of seed-borne pathogens of maize is rather difficult to achieve as a reasonably good. Due to the hazardous environmental effects of chemicals, the Integrated Management of the seed-borne fungal pathogens of corn is mostly preferred. The distribution, disease cycle, symptoms of the damage, effects of environmental factors, economical importance of disease, and integrated disease management options of major seed-borne fungal pathogens of maize have been reviewed in this review article from various currently available sources.

Introduction: Magnesium is very important nutrient and performs a significant part in development and formation of many sink organs like roots and seeds. Furthermore, its fertilization significantly affects yield and numerous physiological mechanisms in different horticulture crop species. Moreover, its deficiency caused germination and reduction in horticulture crop stand. Nevertheless, its adequate concentration by foliar application plays important role in biochemical and physiological processes of plants like proteins synthesis, metabolism of carbohydrates, enzymes activation and energy transferring. Worldwide, many of our horticulture crops are facing low yield and quality problem due to fertilizer application at inadequate rate. The current review focuses on the impact of foliar applied Mg on some important cultivated horticultural crops (sugar beet, tomato, banana, potato, spinach, cauliflower, cassava, garlic, green case, potus, cucumber and grapes). Review results: Our extensive review has demonstrated that magnesium is very important factor limiting horticulture crop production but its negative impacts can be reduced by foliar application of magnesium. Foliar application of Mg can be recommended for correcting deficiencies because foliar sprays have no long term residual effect and every time fresh applications must be given to each crop. Moreover, amount depends on the nutrient status of crop and soil.
