The San Joaquin Valley ACP/HLB Task Force is recommending that growers in a portion of northern Tulare County treat for Asian citrus psyllid. There have been several trap detections over the past 12 months. Two finds north of Seville in mid June are of concern. The Task Force felt that a treatment area larger than 800 meters would be beneficial. At this time, keeping Asian citrus pysllid numbers as low as possible is one of the best defenses we have against the future spread of Huanglongbing.
The Task Force is requesting that all growers in PMAs 82, 83, 85, 88, 89, 92, 95 and 96 (see map below) treat their citrus with a psyllid effective material between September 4 and mid October. This is a time that many of you are already treating for fuller rose beetle. Many growers in these PMAs have been notified but please contact a Central Valley grower liaison with any questions you may have. Earlier suppression treatments in Kern and Tulare Counties have been successful in reducing psyllid numbers for more than a year.
