2010 Annual Report
1a.Objectives (from AD-416)
This project seeks to provide peach farmers with state-of-the-art horticultural and entomological tools and strategies. Specific objectives are to develop improved IPM strategies for peach against Lesser Peach Tree Borer, Peach Tree Borer, and Plum Curculio; and to assist in evaluation of NC-140 rootstock trials, and mineral nutrient physiology.
1b.Approach (from AD-416)
The USDA-ARS Southeastern Fruit and Tree Nut Research Laboratory and the University of Georgia Entomology and Horticulture Departments will collaborate on solving peach production and protection problems affecting southeastern peach growers. This collaborative effort focuses on developing improved horticultural and entomological tools and strategies that are designed to meet the needs of commercial-scale peach producers. Research focuses on development of biological control agents (e.g., nematodes, fungi, and bacteria) to control Lesser Peach Tree Borer, Peach Tree Borer and Plum Curculio. Research also potentially addresses chemical and/or biological control of mites and scale. Horticultural research focuses on establishment and evaluation of a NC-140 Rootstock Trial, improving fruit quality by cultural practices (e.g., nutrient management and pruning), and protecting fruit and trees from pathogens.
This research relates to the inhouse objective: Develop improved varieties of peaches and plums for the southeastern United States, and improved clonal and seedling rootstocks for peach and other stone fruits.
PROGRESS: Collaborative activities, mostly entomology or pathology associated issues, were addressed regarding key insects and diseases of peach in the southeastern U.S. Several field studies were hosted on-site at the Byron location; plus, access was provided to laboratory space and instrumentation involved in pesticide residue analysis.
MONITORING: Progress was monitored by regular site visits, e-mail communications, and phone calls.
