Carroll, Juliet Evelyn

Senior Extension Associate
Carroll is responsible for addressing the pest management issues facing the tree fruit, berry and grape industries of NY through the application of IPM. She works closely with Cornell Cooperative Extension personnel, faculty, legislators, the fruit industry, consultants, and growers. Carroll directed the Plant Disease Clinic at Cornell for seven years and has considerable expertise in plant pathology. Active in Cornell 4H plant pathology development and the American Phytopathological Society’s K-12 youth programs, Carroll has championed plant pathology outreach to youth and secondary teacher audiences. She has conducted research on Dutch elm disease, maple decline, wheat spindle streak mosaic virus, carrot leaf blights, grape powdery mildew, bacterial canker of cherry, and tarnished plant bug. She is author of over 200 extension and research publications and authored a monograph for high school biology teachers. As Fruit IPM Coordinator she carries 20% research and 80% extension responsibilities. Carroll is investigating the impact of copper bactericides and pruning practices on the management of bacterial canker of sweet cherry. Carroll produces Trac Software, a pesticide record-keeping and reporting program for fruit farmers which enables growers to meet market traceability requirements and federal and state pesticide safety requirements. Carroll is leader for the Network for Environment and Weather Awareness (NEWA), a weather mesonet, that provides weather information and IPM forecasts via the Internet.

research and scholarship focus

Carroll is currently studying the impact of copper bactericides and pruning practices on the management of bacterial canker of cherry. In a collaborative study with Greg Loeb on habitat colonization by tarnished plant bug, she determined phenological bloom chronology of over 20 weed hosts. Her research, with Wayne Wilcox, on humidity and its effect on the fungus causing powdery mildew of grapevine significantly advanced our knowledge of the impact that this environmental parameter has on disease development. She elucidated the mode of action of low risk pesticides used to control grapevine powdery mildew and identified diurnal factors involved in the development of disease severity gradients in vineyards along the shores of Lake Erie.

Carroll carries an 80% appointment in Extension and serves as the Fruit IPM Coordinator for the NY State IPM Program in Cornell Cooperative Extension. Carroll developed Trac Software, a pesticide record-keeping and reporting program for fruit farmers, which facilitates traceability reporting to food processors, packers and shippers, and automatically creates EPA Worker Protection Standard Central Posting Forms. Carroll is the current leader for the IPM Program’s Network for Environment and Weather Awareness (NEWA), a weather mesonet, that provides pest and disease forecast models for onions, potatoes, apples, and grapes and weather information online. She secured funding to expand the NEWA mesonet into Eastern NY. She has coordinated the development of IPM Elements and an Integrated Fruit Production (IFP) protocol for apples and helped develop IPM Elements for grapes. Carroll created IPM Element assessment spreadsheets for apple, sweet cherry, strawberry, blueberry, and raspberry. IPM Elements provide a metric for farmers to source funds available through the Farm Bill. She is responsible for content on the Cornell Fruit Resources website http://www.fruit.cornell.edu, on the Fruit IPM website http://www.nysipm.cornell.edu/fruits/, and the NEWA website http://newa.nysaes.cornell.edu. She contributes to the yearly editions of the Cornell Pest Management Guidelines publications for Tree Fruit, Berry Crops, and Grapes. Carroll presents, on average, 20 talks per year on IPM topics to extension personnel and growers.
