Texas root red

The "Texas root rot" (also Phymatotrichopsis root rot or Ozonium root rot) is in Mexico and in the southwest of the United States widespread. The disease was first discovered in 1888. It is caused by the soil fungus "Phymatotrichum omnivora", which affects the roots of plants. This thrives particularly on alkaline and calcareous soils in warm, damp weather. The first symptoms of the disease are common chlorosis on the leaves. Then the leaves brown and withering. After two weeks of the first symptoms, the plant eventually dies.
