Extension and research responsibilities for weed management in nursery crops, Christmas tree production, and landscape plantings. Research interests include: herbicide safety and efficacy in woody and herbaceous perennial plant production and maintenance, optimizing herbicide use patterns for effective weed control and environmental stewardship, ecology of weeds in soilless media and urban landscapes, integrated weed and ground cover management systems, and alternatives to traditional herbicides including plant pathogens for biological control of weeds.
