DOES PESTICIDE USE IN CALIFORNIA OUTDOOR ROSES REFLECT IMPLEMENTATION OF IPM PRINCIPLES?
Production of outdoor rose plants in California has been centered in Kern County. Pesticide use patterns are important for understanding progress and potential targets for integrated pest management (IPM) or other pesticide reduction strategies, as well as providing background information for worker safety, and for risk assessment as urban areas expand into agricultural hinterland. The University of California has a statewide Special Program to foster dissemination of IPM knowledge and application, including emphasis on non-chemical pest management methods where available, as well as use of softer and bio-rational pesticides. Californias total reporting system for pesticides provides specific geolocated pesticide use data for roses and other crops so that pesticide use patterns can be analyzed. We investigated pesticide application data for outdoor rose fields from 1997-2010 to see changes in pesticide use per ha and compared applied mass of pesticides with applications of biorational compounds. We noted kg of active ingredients per ha for major pesticide groups, and noted trends in applications by pesticide type and toxicity category. We then infer the trend toward IPM use in roses and opportunities for additional implementation of IPM principles.
