White and her laboratory work to evaluate the use of plant and bio-based treatment technologies to manage nutrient pesticide, and plant pests carried in irrigation water. She is particularly interested in helping growers clean water so that it can be reused on-farm. She recently led (2014-2019) a national team of researchers from 10 universities that received $8.2 million in funding from USDA-Specialty Crops Research Initiative to evaluate Clean WateR3- Reduce, Remediate, Recycle: Informed Decision-Making to Facilitate Use of Alternative Water Resources and Promote Sustainable Specialty Crop Production. White is Project Director for this grant.

Service: Consulting Editor - Land-Grant Press by Clemson Extension and Nursery crops for the journal HortTechnology. Reviewer - multiple journals. Member - CU Vice President for Research Faculty Advisory Board.

Professional Organizations: International Society for Horticultural Science, American Water Resources Association, American Ecological Engineering Society, Society of Wetland Scientists, Society of Environmental Toxicology and Chemistry, American Society for Horticultural Science, and Southern Region American Society for Horticultural Science.

 Research Interests

White manages and conducts research projects and conveys information related to water management, water quality (chemical and biotic parameters), ecologically-based treatment technologies, and integrated pest management to green industry stakeholders. Investigates the applications of vegetation-based technologies (constructed wetlands, floating treatment wetlands, and vegetated buffers) for cleansing agrichemicals from encouraging reuse of production runoff.

White also advises graduate students, supervises undergraduate students, and serves as the Horticulture Club faculty advisor.

 Extension and Outreach

White is working with the Clean Water3 team to develop information resources for growers to help them make informed decisions related to water management and treatment. Since 2014 the team has published 37 trade articles, 13 extension documents, 29 conference proceedings, and 61 journal articles; released 1 smart-phone application and 2 decision support tools; and made 162 presentations (professional and grower conferences and webinars).

White also works with the Southern Nursery Integrated Pest Management (SNIPM) working group to collaboratively develop Extension resources related to nursery crops, pests, and their management. They have released 3 books, 2 smart-phone applications (IPMPro, IPMLite), and multiple extension documents.
