Which practice is advised to prevent the occurrence of both Gray Snow Mold and Yellow Patch?

Maintaining proper mowing frequency is essential for preventing the occurrence of both Gray Snow Mold and Yellow Patch. When grass is mowed at the appropriate height and frequency, it promotes vigorous growth and healthy turf, which can enhance the plant’s ability to fend off diseases. Proper mowing helps to minimize thatch build-up, which can create a conducive environment for fungal pathogens like those responsible for Gray Snow Mold and Yellow Patch.

In contrast, mowing at improper heights can leave the grass too short or too long, both of which can lead to stress and increased susceptibility to disease. Excessive nitrogen fertilizer can lead to lush, overly soft growth that is more prone to disease, particularly during certain environmental conditions. Frequent daily watering can lead to overly wet conditions that favor fungal growth, particularly in cool weather, making it a risk factor for these types of turf diseases. Thus, proper mowing frequency emerges as a critical cultural management practice for reducing the risk of these turfgrass diseases.
