SouthernCornLeafBlight (SCLB), a fungal disease instigated by the pathogen Cochliobolus heterostrophus, primarily targets corn but can also affect other cereal crops. The disease can cause substantial yield loss, with severe infections sometimes resulting in total loss. Southerncornleafblight was the model pathosystem for the investigation. When corn plants were drench-treated with Bacillus cereus C1L, a rhizobacterium able to induce systemic resistance in corn plants against southernleafblight... Southerncornleafblight is a foliar disease caused by a fungal pathogen Bipolaris maydis, anamorph or Cochliobolus heterostrophus, teleomorph. Based on morphological characteristics, the colony colour of the pathogen was found to be grey, grey to green, dark grey and light grey. Southerncornleafblight incited by Helminthosporium maydis Nisikado & Miyake evolved from a minor disease that causes an average annual loss of less than 1 percent, to one that caused more than the 12 percent average expected from all diseases of corn in the United States. Southerncornleafblight (SCLB), caused by the fungus Cochliobolus heterostrophus (also known as Bipolaris maydis), has been observed at several locations in the Lower Rio Grande Valley in the fall corn crop this past month. The southerncorn (Zea mays L.) leafblight (SCLB) epidemic of 1970–1971 was one of the most costly disease outbreaks to affect North American agriculture, destroying 15% of the crop at a cost of US$1.0 billion (≥$6.0 billion by 2015 standards.). Southernleafblight (SLB) is a foliar disease caused by the fungus Cochliobolus heterostrophus infecting maize plants in humid, warm weather conditions. SLB causes production losses to corn producers in different regions of the world such as Latin America, Europe, India, and Africa. Southerncornleafblight is found in all corn production areas of the world. It is most prevalent though in the warm temperate and humid subtropical regions. According to Robert (1953), SCLB (no race designation) was first discovered in the United States in 1923. Southerncornleafblight is caused by the fungus Bipolaris maydis. There are two races of the pathogen. Race O normally attacks only leaves. Lesions are tan, somewhat rectangular in shape, and have reddish-brown margins.
