AGRO INFORMATION

The arrival of human in an area, to live or to conduct agriculture necessarily has environmental impact, these range from simple crowding out of wild plants in favor of more desirable cultival to larger scale impacts such as reducing biodiversity by reducing food availability of native species which can propagate across food chains. The use of agricultural chemical such as fertilizer and the magnify those impact while advance in Agro chemistry have reduced those impact for example by the replacement of long lived chemicals with those that reliably degrade, even in the best case they remain substantial ,these effect are magnified by the use of older chemistries and poor management practices.

Maize or corn is a cereal crop that is grown widely throughout the world in a range of agroecological environments. More maize is produced annually than any other grain. About 50 species exist and consist of different colors, textures and grain shapes and sizes. White, yellow and red are the most common types. The white and yellow varieties are preferred by most people depending on the region. Maize was introduced into Africa in the 1500s and has since become one of Africa’s dominant food crops. Like many other regions, it is consumed as a vegetable although it is a grain crop. The grains are rich in vitamins A, C and E, carbohydrates, and essential minerals, and contain 9% protein. They are also rich in dietary fiber and calories which are a good source of energy. Importance Maize is the most important cereal crop in sub-Saharan Africa (SSA) and an important staple food for more than 1.2 billion people in SSA and Latin America. All parts of the crop can be used for food and non-f...

Cochliobolus miyabeanus (formerly known as Helminthosporium oryzae) is a fungus that causes brown spot disease in rice. This disease was the causal agent of the Bengal famine of 1943. Local name: Kandu, Chukke, Roga Period of occurrence: Seedling to maturity Extent of yield loss: 50-90% in extreme cases Mode of transmission/ dissemination: wind Sources of inoculum: Seed, Collateral hosts, Rice straw or Stubble Hosts and symptoms  Brown spot of rice is a plant fungal disease that usually occurs on the host leaves and glume, as well as seedlings, sheaths, stems and grains of adult host plants. Hosts include Oryzae sativa (Asian rice), Leersia (Cutgrass), Zizania (Wild rice), and other species as well such as Echinochloa colona (junglerice) and Zea mays (maize). Cochliobolus miyabeanus may cause a wide range of symptoms. General symptoms occurring on the hosts can be observed on many parts of the plant, including leaves, seeds, stems and inflorescences, along with the pres...
