摘要

The Pink Double Knock Out roses were grown in no. 3 nursery containers under 45% shade at a commercial nursery in Smithville, TN. Plants were fertilized with 1.6 oz of 18-6-12 Osmocote Classic on 1 Jun. Four single-plant replications per treatment were arranged in a randomized complete block design. Rose plants were watered daily using overhead impact sprinklers. The initial sprays were applied when disease was first observed on leaves. Treatments were applied to run-off using a backpack CO2 -pressurized sprayer at 40 psi. The first application occurred on 22 Jun for all treatments. The second applications for 7-day interval treatments was made on 29 Jun, and 14-day interval treatments on 6 Jul. The severity of downy mildew was evaluated on 29 Jun;6, 14 and 22 Jul using a scale of 0-100% foliage affected. Rose plants also were rated for downy mildew by counting the total number of infected leaves per plant on 22 Jul. Mean plant width and height were measured on 22 Jul. Average maximum temperaturesfor 22-30 Jun and 1-22 Jul were 90.0 and 89.1°F, average minimum temperatures were 67.9 and 69.2°F, and total rainfall amounts were 2.73 and 2.87 in, respectively. Analysis of variance was performed using the general linear models procedure with SAS statistical software and means were separated using Fisher's least significant difference test.
