Eric farmed Satsuma mandarin oranges in the Sierra Nevada foothills. One year when his fruit began to mature, rainy weather caused what appeared to be a fruit rotting disease. Eric came close to losing his entire crop. He called his local UCCE farm advisor to see if there was a way to prevent the same thing from happening again next year. UCCE advisors and researchers launched a collaborative research project to study Eric’s crop, and after four years of field trials they were able to determine the specific reason for his crop loss and develop a long-term strategy to help him avoid future losses. Eric was able to keep the problem from recurring and continues to sell his delicious mandarin oranges direct to the public.
