Our research program aims to understand current as well as emerging diseases of major fruit and nut crops, and deliver efficient and innovative control strategies. We study a wide variety of fruit and nut crops including Almond, Pistachio,  Cherry,  Citrus and Olive.  Research includes basic and applied studies on the etiology, biology, epidemiology and control of fruit and nut crop diseases. We work closely with farmers, pest control advisors  and UCCE farm advisors to help them grow healthier crops, improve the quality of California products, and ensure the prosperity of the farming industry. As an extension lab, we offer a plant disease diagnostic service  for perennial fruit and nut crops in California, see our “Diagnostic Services” page.
