Wheat leaf rust Wheat leaf rust Wheat leaf rust is a fungal disease that affects wheat, barley and rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% yield loss, which is exacerbated by dying leaves, which fertilize the fungus. The pathogen is "Puccinia" rust fungus. "Puccinia triticina" causes "black rust", "P. recondita" causes "brown rust", and "P. striiformis" causes "yellow rust". It is the most prevalent of all the wheat rust diseases, occurring in most wheat growing regions. It causes serious epidemics in North America, Mexico and South
Wheat leaf rust several names, we have an appropriate name for WLR Life cycle: Wheat leaf rust spreads via airborne spores. Five types of spores are formed in the life cycle: Urediniospores, teliospores, and basidiospores develop on wheat plants and pycniospores and aeciospores develop on the alternate hosts.[10] The germination process requires moisture, and works best at 100% humidity. Optimum temperature for germination is between 15–20 °C. Before sporulation, wheat plants appear completely asymptomatic. "P. triticina" has an asexual and sexual life cycle. In order to complete its sexual life cycle "P. triticina" requires a second host "Thalictrum" spp. on which it will
