INTRODUCTION Maize (Zea mays L.) is one of the most important food crops of the world. 1. During Black bundle and Late wilt disease, the infected plant shows symptom after reaching tassel state. Moderate phytosanitary importance, high potential economic importance. Maize is subjected to as many as 112 diseases on a global basis. = Botryodiplodia theobromae Pat. 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. 2 Brown spot Physoderma maydis The disease normally occurs in areas of high rainfall and high mean temperatures.
