Photographs at right were taken on Aug. 29 in a neighborhood where more than 50% of properties had significant chinch bug damage.
The level of damage illustrated in the photos was common in newer developments where closely mowed turfs lay over thin, sandy, low organic matter soils in highly exposed situations.
What was more notable than the damage, however, was the presence of entirely undamaged lawns in the midst of the damaged lawns.
One might speculate that pesticides were used on the undamaged lawns, and not on the damaged lawns. However, the juxtaposition of lawns heavily damaged by chinch bug (treated or not treated with pesticides) and completely undamaged lawns (not treated with pesticide) is a well known phenomenon; [L1] it shows very clearly that a healthy lawn is resistant to chinch bug.
Pooh on Lawns "What is a healthy lawn"? asked Piglet.
"A healthy lawn is one that is resistant to pests and diseases," replied Pooh.
"What makes a lawn healthy?" asked Piglet.
"Now, that's the interesting question," said Pooh.
