What is a sign of petroleum injury in turfgrass?

• A. Patches of green grass
• B. Irregular patches of dead turf
• C. Uniform ground cover
• D. Deep soil moisture

Answer: (B)

Irregular patches of dead turf serve as a clear indication of petroleum injury in turfgrass. When turfgrass is exposed to petroleum products, it can cause localized damage that manifests as dead or dying areas within the lawn. This injury affects the plant's ability to photosynthesize and can lead to the widespread die-off of specific patches due to the toxic effects of the petroleum compounds. The irregularity of the patches often distinguishes petroleum injury from other types of turfgrass issues, which might cause more uniform patterns of damage. Understanding this helps turf managers identify and remediate the problem effectively, ensuring the health of the remaining grass and proper management of any contaminated areas. Recognizing these irregular patches is crucial for taking timely action to mitigate further damage and restore the health of the turf.
