Pest identification
What's eating my ichi ki kei jiro persimmon?
Scale insects (white peach scale, tuliptree scale)
Signs: Hard or waxy encrustations on bark; yellowing foliage, branch dieback, and sticky honeydew coating leaves beneath.
Control: Apply dormant horticultural oil thoroughly in late winter; prune and destroy heavily infested branches; monitor in summer with sticky traps.
Persimmon borer (Sannina uroceriformis)
Signs: Larvae excavate tunnels in lower trunk and root crown; frass visible at soil line; severe infestations girdle and kill the tree.
Control: Avoid trunk injury; remove weeds and excess mulch from base; inject beneficial nematodes into entry holes or broadcast around the drip line in late summer.
Leafrolling caterpillars
Signs: Leaves rolled and tied with silk webbing; larvae feed inside, leaving ragged holes and reducing photosynthesis.
Control: Hand-pick rolled leaves and destroy larvae; spray Bacillus thuringiensis (Bt) at caterpillar hatch; encourage parasitic wasps by planting nectar plants nearby.
Deer
Signs: Buck rub strips bark in autumn; winter browsing of shoots and low branches can set back young trees by an entire growing season.
Control: Install sturdy tree guards or chicken-wire cages at least 1.5 m tall; spray antler-rub repellent from late summer; fence the orchard where deer are numerous.
