2019 Annual Report
Objectives
Evaluate various fungicides, insecticides, and herbicides for phytotoxicity and/or efficacy on floral and nursery crop plants in support of label expansion through the IR-4 regional project.
Approach
Selected floral and nursery crop species will be grown in the greenhouse, ground beds, or field plantings and treated according to specific protocols (timing, concentrations) with selected fungicides, insecticides, or herbicides. In some cases, chemicals will be tested for efficacy, but mostly they will be tested on plants for phytotoxicity. Data will be submitted for inclusion in the IR-4 Minor Use Testing Program.
Progress Report
Researchers in Corvallis, Oregon, conducted 30 crop safety trials. Trials were conducted with seven different fungicides on a wide range of plant material. Treatments included eight trials using BAS 750 02F, three trials with NF-171, two trials using SP2700 AS, four trials with Orkestra Intrinsic, six trials with Picatina (A19649B), three trials with S2200 4SC, and four trials using Segovis. The results of these tests were reported to the IR-4 project at Rutgers University and were forwarded to the product manufacturer to be used in their request to expand the label to include the tested ornamental plants. Eventually, with label expansion, growers should be able to legally use these chemicals on ornamental nursery crops. All objectives were achieved. This information will aid significantly in registering novel fungicides or biologicals for managing diseases of minor crops including ornamentals.
