Disease is caused when the normal growth of the lawn turf is disrupted because of its interactions with pathogens like fungus. The pathogen comes from the environment and hinders the growth of turf grass.
Diseases generally occur where the environment is floods with pathogens. Moreover the plants which are more stressed are prone to disease as compared to unstressed plants.
How can disease be prevented
• Adequate drainage is necessary
• Species or cultivars which are resistant to plant disease are important
• Don’t allow over-fertilizations
• Dot allow the leaves to stay really wet over a period of time
• Maintaining adequate air movement both below and above the ground
• No watering in the evening
Effect of disease on water quality
Disease can be fatal for plants and leaves bare soil which becomes prone to erosions and runoffs. If the chemicals are misapplied, it can pollute the runoffs and can seep into the groundwater.
Preventing disease
If the turf grasses can cope up with the stress, it will be healthy and dense and will be able to resist disease. Sometime the disease may spread and it becomes out of any control. However, the disease resistant cultivars can be implemented to avoid future problems.
