Cotton Root Rot (Phymatotrichopsis omnivora) is a very interesting soil-borne fungal disease. It is one of the more serious diseases because it can infect over 2,000 species of plants and there is no treatment. Monocotyledonous plants such as asparagus fern, lillies and grasses have field resistance but cotton, many types of crops, fruit, nut and shade trees are susceptible.
Brenerria quercina or Drippy Acorn is favored by heat, moisture, and insect wounding. The bacterium enters the acorn shell through puncture wounds, which a variety of insects cause during egg laying and feeding.
Phytophtera root rot is a fungal pathogen that affects many types of trees and plants. It is a soil-borne disease found on living roots that can survive for long periods of time without a host. Most often, Phytophtera is found on sites with poor draining soil and/or excessive irrigation.
