Daniel Cooley

Dan’s teaching, research and Extension work at UMass focuses on managing plant diseases, and the impacts plant diseases and their management have on environmental and human health. Much of his career has studied major apple diseases, including apple scab, summer diseases and fire blight. Apples are heavily sprayed with fungicides to manage apple scab, and often require one to three antibiotic applications per year for fire blight. A primary research goal is an improved understanding of the ecology of apple pathogens resulting in improved disease management with less chemical use. As part of this, his group studies disease forecast models and web-based decision support systems for collecting and analyzing weather and crop, and works to improve their recommendations to growers. He has frequently done on-farm research projects with growers to improve Integrated Pest Management in fruit crops, as well as promoting adoption of IPM methods. Recently, he has been developing resources to advise farmers and the public on the impacts of climate change on agriculture in New England, and potential methods for adaptation and mitigation. Dan teaches courses in plant disease management, and a course looking at the relationship between agriculture, food and diseases, including human health, as well as coordinating a graduate seminar on plant diseases. More Information.
