Oriental Fruit Moth: Growers who have used mating disruption for OFM should continue to focus on PC; GPA; and catfacing insect pests as described below. For those growers using insecticides, the first of 2 applications in northern counties is due this week, and the second of 2 applications in southern counties is due next week. This is particularly important where the moth flight is exceeding the treatment threshold of 8 moths per trap. [Read more…]

Cicadas are Here, There and Everywhere (Depending where you are): 17 year cicadas began emergence last week. These insects while a marvel in the insect world, are also capable of doing considerable damage to young fruit trees, grape vines, and blueberry bushes. After mating they begin to deposit their eggs in slits along small diameter branches. Thin branches which are loaded with fruit weight and damaged by egg laying can break. Some growers have asked about damage and what they can do to prevent it. Most egg laying is starting this week.
