Leaf Curl is not normal for asian persimmons. This
problem is usually caused by the persimmon psylla.
The adults have small, black-bodies(gnat size) with
large, transparent wings that extend at approximately
a 45 degree angle to their bodies while at rest

D. Virginiania and lay eggs on the leaf margin,
underside. The hatched nymphs inject a toxin that
causes the leaf to curl around them. Control is with
an insecticide such as malathion.
