Web blight uri icon


  • Web blight, caused by the fungus Thanatephorus cucumeris, is prevalent in tropical regions with high to moderate temp. and RH; more than 200 plant species serve as hosts to this pathogen. Hyphae can grow rapidly over healthy tissue of leaves, flowers, petioles, and pods. For efficient control, the use of disease-free seeds, elimination of harvest debris, crop rotation, mulching, using spaced furrows and intercropping; the use of adequate chemical products, the use of resistant var., and integrated control are also recommended. The symptoms and damage caused by the disease are illustrated in color. (CIAT)
