Navel Orangeworm Damage Predictor
A new model to help predict navel orangeworm (NOW) damage is being developed by entomologist Brad Higbee with Paramount Farms and Joel Siegel, USDA-ARS-Parlier. The model, currently being validated, provides a tool that growers and PCAs can use to assess expected results and project the outcome of different treatment options.
This teaching tool version of the model, based on Kern County conditions and data, is available to see how different scenarios can impact final NOW damage. Though this version is specific to the Southern San Joaquin Valley, it underscores longstanding basics; in particular, that sanitation—removal and destruction of both tree and ground mummies—is a priority. After this, harvest timing, early vs. later, is important. Specific to the southern San Joaquin Valley is proximity to pistachios, which harbor higher NOW populations.

VOC Emissions Calculator
The Department of Pesticide Regulations (DPR) has developed a web-based tool for calculating volatile organic compound (VOC) emissions from agricultural applications of nonfumigant pesticides. You can calculate VOC emissions from single or multiple pesticide products and applications. Start a VOC emission calculation
