Walnut growing is big business in California, with crops of better than 450,000 tons in recent years putting the state’s production second only to that of China. A very serious disease called walnut blight at one point threatened to put an end to walnuts in California. In response, UCCE used funding from the California Walnut Board to put together a team of specialists and advisors, partnering with faculty at UC Berkeley and UC Riverside, to study the disease. The team identified pesticide application techniques that provide effective protection for the trees while actually reducing the overall amount of pesticides applied. Working together, these UC researchers saved the California walnut industry.
