Which environmental factor can affect the onset of diseases?

Temperature and humidity are critical environmental factors that significantly influence the onset of diseases in turfgrass and other plants. Many pathogens, including fungi and bacteria, require specific ranges of temperature and humidity to thrive and infect host plants.

For example, high humidity levels can create a conducive environment for fungal spores to germinate and infect the plant, while higher temperatures can accelerate the life cycles of pathogens, leading to an increased incidence of disease. Conversely, low humidity and cooler temperatures can slow down pathogen activity and reduce the likelihood of disease development.

Understanding how these factors interact helps turf managers implement effective preventive measures and adjust their maintenance practices, such as irrigation and fertilization, to mitigate disease risks during susceptible environmental conditions. This knowledge is essential for maintaining healthy turfgrass in varying climates.
