How can improper cultural practices affect turfgrass diseases?

• A. They can enhance disease resistance
• B. They can stress the turf and exacerbate diseases
• C. They can eliminate the need for fungicides
• D. They can promote healthy root growth

Answer: (B)

Improper cultural practices can significantly stress turfgrass, making it more susceptible to diseases. This stress may arise from various factors, such as overwatering, inadequate fertilization, improper mowing heights, or poor soil conditions. When turfgrass is stressed, its overall health declines, reducing its natural defenses against pathogens. For instance, mowing too short or at the wrong time can weaken grass plants, leading to vulnerabilities that diseases can exploit. Additionally, practices that lead to excessive thatch accumulation or poor air circulation can create ideal environments for pathogens to thrive. Therefore, the improper management of cultural practices not only creates conditions that are conducive to the development of turfgrass diseases but can also lead to more severe outbreaks when the turf is under stress.
