How to Manage Pests

Pests in Gardens and Landscapes

Sunblotch

Symptoms of sunblotch include yellowish or white streaks on fruit. Twigs may also have streaks. Avocado trees may be stunted, and fruit yield may be reduced.

Solutions

Sunblotch is caused by a viriod, transmitted through seed or by grafting. Be sure to use clean seed and budwood. Remove infected trees.
