VOCs are gasses that combine with other substances to form ground level ozone (smog). In an effort to reduce smog in the San Joaquin Valley, as of Nov 1, the Department of Pesticide Regulation (DPR) is restricting sales and use of High-VOC producing ag products during the months of May through October. High-VOC ag products have an emission potential (EP) greater than 35%. For citrus, products of concern include chlorpyrifos, gibberellin, abamectin and oxyfluorfen. There are many formulations of each of these agricultural products and the goal is to choose formulations that keep the EP below 35%. The following link provides a list of the formulations that are above (High-VOC) and below (Low-VOC) the EP threshold of 35% for all crops. Keep this in mind as you purchase and use insecticides, herbicides and gibberellin.

California’s Department of Food and Agriculture (CDFA) establishing a quarantine area around the Asian citrus psyllid (ACP) detection sites in Tulare County. It is estimated that there are 11 packing houses and 21,520 acres of commercial citrus that fall within the quarantine area, which is approximately a five mile radius around the detection sites.
All fruit leaving the quarantine area must be cleaned of leaves and stems before it is moved from the quarantine area. At the present time, groves cannot be treated with pesticides as an alternative to cleaning. CDFA has requested approval from USDA’s Animal and Plant Health Inspection Service (APHIS) to implement this option, but APHIS has not approved it as of today. Compliance agreements are required for growers, haulers and packers if fruit is moved from the quarantine area. Parties should contact CDFA’s ACP Exclusion Office in Visalia at (559) 636-7410 for additional information about compliance agreements.
This information is in from Tulare County:
The California Department of Food and Agriculture (CDFA) announced yesterday that six adult Asian citrus psyllids (ACP) were found in three separate Glassy-winged sharpshooter traps in commercial citrus groves in southwest Porterville. The traps were set on June 11 and serviced on June 26. CDFA and Tulare County are establishing an eight square mile intensive trapping zone around the detections to determine if there may be other ACP in the vicinity.
CDFA, USDA/APHIS and County of Tulare will be meeting to determine the appropriate course of action and whether to impose a quarantine zone or other regulatory measures. CDFA will meet Monday (July 15) with the Executive Committee of the Citrus Pest and Disease Management Committee regarding its plans for addressing the infestation.
More information will be provided as it becomes available.
