Disease Process

There are many steps in the disease process, and enviromental conditions play a role in them all. Innoculation is when the pathogen comes in contact with the plant. This is always occuring on lawns. Infection is when the pathogen actually enters the plant via wounds, improperly cut leaf tissue, or natural openings. A fungus infecting a plant doesn't automatically imply disease. A pathogen must become established inside a host for the host to exhibit disease. It is at this time when the pathogen starts to disrupt the normal growth of the plant or affect the appearance. Depending on the pathogen, it may reproduce via spores. These spores may then spread to other parts of the plant.

A disease is an interaction between a plant and a pathogen that disrupts the normal growth and appearance of a the plant.

Management steps to control disease include correctly identifying the disease, the conditions promoting the disease, and management techniques to alter or eliminate the disease.

Cultural practices include selecting the proper turf-grass for the area, RIGHT PLANT RIGHT PLACE! Proper mowing, proper irrigation, and proper fertilization.

Every maintenance practice, fertilizer application, and chemical application, especially herbicides, have an impact on turf-grass health.
