In order to manage large patch fungus, it is important to:

• A. Increase watering
• B. Avoid overwatering in fall and early spring
• C. Mow short
• D. Apply fertilizer

Answer: (B)

Moisture control is crucial for managing large patch fungus. This disease flourishes when turf stays wet, especially during cool, wet fall and early spring conditions. By avoiding overwatering in these periods, you reduce leaf wetness and saturated soil, making it harder for the fungus to infect and spread.

Increasing watering only adds moisture that fuels the pathogen. Mowing short doesn’t address the moisture issue and can stress the turf, potentially worsening problems. While fertilizer supports general turf health, it doesn’t directly prevent large patch and can even keep leaves wet longer if overapplied. Focusing on reducing unnecessary irrigation and improving drainage during the vulnerable seasons is the most effective approach.
