Billbug damage presents as which pattern on turf?

• A. Patches of yellowing turf with thinning roots and crown/stolon feeding injury
• B. Patchy thinning with no crown damage
• C. Dense green patches with excessive rooting
• D. Uniform dyeing across the entire lawn

Answer: (A)

Billbug damage shows up as patches of yellowing turf with thinning roots and injury to the crown and stolons because the larvae feed on the root zone and crown tissue, weakening and killing those areas while surrounding turf stays healthier. That creates distinct, irregular patches rather than uniform or overall color change. The other patterns don’t match billbug feeding: thinning without crown damage isn’t typical of billbugs, dense green patches with excessive rooting imply another issue, and uniform dyeing suggests a problem affecting the entire lawn rather than localized feeding damage.
