2012 Annual Report
In total, we conducted 23 trials for Metconazole and Triticonazole, 6 trials for Acibenzolar, and 5 trials for Fluopicolide on a range of ornamental plants. Tests were run using the Interregional Research Project No. 4 protocols wherein chemicals are applied up to 1X-4X rates. The results of these tests were reported to the IR-4 project at Rutgers University and are 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 be should able to legally use these chemicals on ornamental nursery crops.
We also conducted trials to evaluate efficacy of fungicides for control of Pythium damping off on douglas fir seedlings. Specific Pythium species used in this study were P. vipa, P. dissotocum, and P. irregulare. Experiments were conducted by planting Douglas Fir seeds in 0.45L plastic pots with 10 seeds per pot. Pots were arranged in a randomized complete block design with 8 replications. Treatments included: a noninoculated control, Adorn, Aliette, Alude, BW240WP, BW240+Al, Cg100, Disarm, Fenstop, Heritage, Pageant, Subdue Max, and a nontreated control. Disease development in these trials was inconsistent and the experiments are thus being repeated in 2012.
