Root Rot

The most common Root Rots are Pythium, Rhizoctonia, Fusarium Root and Crown, and Take-All. These all derive from fungi which are soil-borne and are easily transferred to the root systems of susceptible plants. These diseases are similar to Leaf Complex in that there may be more than one present and infecting host plants at any given time. Spores are quickly spread by wind, water, cultivation and infected seed. Symptoms may go unnoticed or mistaken for an environmental or pesticide damage problem. Root Rots attack most cereal crops in the same fashion and reduce tillers and seed size which reduces yield and quality of grain.
