Infested leaves roll and curl up on themselves. Psyllid are often limited by natural parasites. Don't apply insecticides until after you have observed damage. Caterpillars such as fall webworm, red-humped caterpillar and variable oak leaf caterpillar will occasionally infest persimmons. These pests also tend to be heavily parasitized, limiting their importance as pests.
Insecticides are effective where damage warrants use.
Persimmon borer is a serious pest of native and oriental persimmons. It has been seen attacking oriental persimmons in Georgia, although it is known to infest both species in other states. Its larvae attack the lower trunk and tap roots. Where infestations occur, preventative insecticide treatments similar to those made for peachtree borer will be required. Other sporadic pests of persimmons include ambrosia beetles that attack where bark is injured or sunscalded.
