New findings on pistachio problems
by Richard E. Rice , Jerry K. Uyemoto , Joseph M. Ogawa , Wynette M. Pemberton
pp15-18, doi#10.3733/ca.v039n01p15
Abstract
A little over a year ago, the leaffooted bug (on the cover) was, for the first time, implicated in epicarp lesion of pistachios. Now it has been learned that several other species of true bugs can also cause some pistachio nut disorders. A fungus is the culprit in other cases. Still others remain a mystery.
