The fungus reproduces asexually, and no perfect stage has been identified 4]. This disease was first reported as a vascular wilt disease of corn in Egypt in 1960 [5] and is now considered endemic throughout Egypt. Identifying disease issues at harvest makes growers better prepared to select hybrids for the coming season. Symptoms: This disease of maize is caused by two organisms. Brown spot (black spot, stalk rot) Physoderma maydis (Miyabe) Miyabe Cephalosporium kernel rot The lower disease index of 23.52 % with 14.00% incidence was recorded in Khaskusum area of Banke district followed by Surkhet having 43.57% PDI and 29.00% incidence where crop Cephalosporium maydis.

In recent years, maize area and production has shown a steady increase, but productivity hill (72.85%), terai (17.36%) and high hill (9.79%) respectively. Disease Management. Three species of arbuscular mycorrhizal fungi (Glomus fasiculatum, Glomus mossae and Acaulispora laevis) were used as bio-agents to manage black bundle disease of maize caused by C.acremonium. Taxonomy. Brown spot. Reduction in growth and yield is demonstrated. Black Bundle Disease and Late Wilt: Causal organism: Cephalosporium maydis, Caphalosporium acremonium. 1963). Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants.

Widespread incidence and severity in Egypt, with 100% infection reported in some fields. Maize is subjected to as many as 112 diseases on a global basis. Although abundantly detected in all seed samples tested, this fungus has not yet been reported to cause any disease in field in Burkina Faso. Introduction. Late wilt, a severe vascular disease of maize caused by the fungus Harpophora maydis, is characterized by relatively rapid wilting of maize plants before tasseling and until shortly before maturity.
