New seedings are very susceptible and can be permanently damaged, so be sure to check these fields. Adult PLH are 1/8th of an inch long, lime-green and wedge-shaped. They insert a stylet into a leaf midrib and inject a toxin that results in a wedge-shaped yellow “hopperburn”. Damage is often confused with moisture and heat stress. Scouts…
