She is a Senior Extension Associate with the Department of Plant Pathology of Cornell University, stationed at the Long Island Horticultural Research Laboratory in Riverhead, New York. Margery has a bachelor's degree in biology from the College of William and Mary and a master's degree in plant pathology from the University of Massachusetts. Her extension education program focuses on teaching effective disease management for greenhouse and nursery crops and landscape ornamentals. Margery has first-hand familiarity with proper identification through the ornamental plant disease diagnostic lab she directs on Long Island. She also conducts research on disease management and has participated in many local and national programs on disease avoidance.

A.R. Chase was Professor of Plant Pathology at the University of Florida for 14 years.  She specialized in diseases or foliage plants and cut foliage crops during here tenure there.  Ann earned a BS in Biology in 1976 and a PhD in Plant Pathology from the University of California at Riverside in 1979 and has worked in ornamentals ever since.  She started Chase Horticultural Research in 1994 when she returned to California.  Chase Horticultural Research conducts research in disease control on all ornamentals as well as running a diagnostic lab open to growers and landscapers in the continental US.  Ann continues to give presentations on research results as well as writing a monthly newsletter, Chase News.

• Foliar diseases - Botrytis, Xanthomonas, Pseudomonas, rust, leaf spot, powdery mildew, downy mildew
• Root and stem diseases - Rhizoctonia, Phytophthora, Pythium, Sclerotinia, Sclerotium, Alternaria, canker, crown gall, vascular wilt
• Virus and mycoplasma diseases - cucumber mosaic virus, impatiens necrotic spot virus, tomato spotted wilt virus, aster yellows
• Other problems that mimic diseases - excessive soil moisture, nutrient deficiencies, high temeratures, genetic abnormalities

Plus, eleven reference tables provide succinct information, including:

• Nonchemical controls for diseases
• 166 annuals and perennials by scientific and common names
• Plants most susceptible to foliar diseases, root and stem diseases, and mycoplasma diseases
