Monitoring Peach Twig Borer Development with Degree-Days by Richard E. Rice, Frank G. Zalom, & Jay F. Brunner The development of the peach twig borer Anarsia lineattela Zeller (PTB) can be monitored using pheromone traps and local temperature.

Omnivorous leafroller Omnivorous leafroller (Platynota stultana) is primarily a pest of peaches in the San Joaquin Valley. It occurs in the Sacramento Valley, but seldom causes damage. Omnivorous leafroller overwinters as immature larvae in mummy fruit and does not enter dormancy.

Oriental fruit moth Adult oriental fruit moths (Grapholita molesta) are small grayish moths about 0.4 inch long. These moths normally fly in the evenings just after sunset, or occasionally between daybreak and sunrise. Eggs are disk shaped, white to creamy in color when first laid, and about 0.

San Jose scale Female San Jose scale (Quadraspidiotus perniciosus) give birth to living young that emerge from under the edge of the scale covering. These tiny yellow crawlers wander in a random fashion until they find a suitable place to settle.

Panicle and shoot blight, caused by a Fusicoccum sp. (e.g. Botryosphaeria dothidea), is the most serious disease of California pistachios. Fusicoccum is entirely splash dispersed. Infections which occur during early season spring rains can remain latent until later in the growing season.

By converting from flood to buried drip irrigation, the orchard microclimate can be altered to improve the yield of marketable fruit, without fungicide sprays. Alternaria late blight symptoms are apparent on pistachio leaves, above.
