VIBURNUM (Viburnum plicatum ‘Mariesii’)
Ramorum blight; Phytophthora ramorum

Efficacy of registered and unregistered fungicides for control of Ramorum blight on Viburnum, 2009.
This study was conducted as part of the IR-4 Ornamental Horticulture Program to evaluate fungicides for
managing foliar diseases of ornamental plants caused by Phytophthora ramorum. Because P. ramorum is a
pathogen under federal quarantine, experiments had to be conducted in containment on detached leaves.
Viburnum plants grown in 3.8-L plastic pots were obtained in May and maintained outdoors in shade conditions
with daily hand watering. Four single-plant replications were arranged in a randomized block design. Treatments
consisted of a fungicide application on 21 Aug or 25 Aug of either a spray or drench. Foliar applications were
applied to run-off using a hand-pump sprayer. Drenches were applied until soil was saturated. Either seven or
three days depending on product after fungicide application, three leaves from each plant were removed for
detached leaf inoculations under quarantine containment conditions. Leaves were placed in plastic containers with
500 ml moistened vermiculite. Separate containers were used for each chemical treatment. Each leaf was needlewounded once on the abaxial side to the right of the midvein just prior to inoculation with P. ramorum strain 0374-N10A (A2 mating type isolated in OR). A 20-µl drop of inoculum (3,500 sporangia/ml) was applied to each
wound site. Non-inoculated controls received an equivalent drop of sterile distilled water. After inoculation,
leaves were misted and containers were placed in an incubator at 20ºC with a 14-hour light cycle for ten days.
Disease severity was determined by evaluating lesion area from digital images using ASSESS software (APS, St.
Paul, MN) on day seven. Lesion area was subjected to analysis of variance (JMP 8, SAS Institute, Cary, NC). All
experiments were conducted in a containment growth chamber following standard operating procedures approved
by USDA APHIS.
Chemical treatments had a significant effect on lesion area observed. However, not all chemicals had the
same efficacy in reducing lesion expansion. Aliette, Captan, Stature DM, NOA 446510, BASF 651F (low rate
only), and V-10161 were not significantly different from the untreated, inoculated controls. Disarm, BASF 651F(
high rate), CG100, Regalia SC, and Subdue MAXX were most effective in reducing disease severity. All
chemicals were effectively fungistatic, not fungicidal, after confirmation of the pathogen's viability by isolation
and subsequent culture of the pathogen from wound sites on symptomless leaves. No phytotoxicity was observed
for any treatment. The non-inoculated control showed no lesions.

Narrative Summary of Methods
Plants were obtained from a nursery in 4" liners. They were transplanted into 1 gallon pots
and hand-watered as needed. The plants were grouped into random blocks of 8 plants each
and the chemical treatments were applied. Observations for phytotoxicity were performed 7, 14 and 28 days
after each of the 2 applications. No phytotoxicity was observed on any plants at any of the observation dates.
The plants were 8" to 10" in height and they were well formed and saleable.
