Director’s viewpoint l Steve SauterMembershipHas Its Benefits!TheKentucky Landscape Industries Winter Conference at the KentuckyInternational Conference Center — hosted by the Kentucky Nurseryand Landscape Association, Kentucky Arborists’ Association, Kentuckiana GreenhouseAssociation and the University of Kentucky Cooperative Extension Service — had a greatturnout and excellent feedback. Along with fabulous educational speakers, exceptionalexhibitor displays ranged from new variations of plants to innovative and time-savingequipment for all types of operations.Conferences such as this are of great benefit to the green industry; they provide CEUcredits not only for pesticide license holders but also for certified arborists and landscapearchitects. They are also great sources of knowledge that allow green industry companies todistinguish themselves from their competitors. Knowledge gained at these conferences isnot just for owners and supervisors but also for every employee. Employees are the ones whohave more frequent interactions with customers, and having well-educated employees willtake a company to a new level in the eyes of the customer. Being well informed on the topicsof our industry and in your own company is critical in having a successful company andsuperior reputation that will set a higher standard for the industry as a whole.Organizations like the KNLAprovide its members with access tothese conferences and outings thatbenefit not only the members butalso, in turn, their customers andthe environment itself. Keeping thisin mind, boosting our membershipwould be of great service to the KNLAorganization and others, and whobetter to spread the word of an organizationthan the ones who truly reapthe benefits, its members? To help theKNLA continue to work for you, pleasetalk to your fellow horticulturists aboutjoining. People eligible for membershiprange from lawncare providers to horticultureeducators and horticulturestudents. Who better to join the KNLAthan the future of the horticultureindustry, the youth? Like I always say,“Many hands make light work,” so let’sband together and allow the KNLA tocontinue its great work.Nursery Views / Spring 20128Steve SauterLawnco, LLCLouisville, KY

Plant ProfileBy Winston Dunwell, Ph.D., The University of KentuckyWhenI first moved to west Kentucky in 1979,there was a plant that flowered in thewinter in the farm superintendent’s yard.I never paid it much attention and truthfully did not know whatit was because the only thing I expected to see showing color inFebruary was Hamamelis, the witchhazels. The fact that it wasThe bright yellow bloom of Cornelian cherry dogwood ‘Spring Glow’ (C. mas).17Nursery Views / Spring 2012

FROM THE PRESIDENT l Mike DreisbachTop: Chimonanthus praecox, fragrantwintersweet, another yellow-floweredwinter bloomer.Bottom: Another winter bloomer, Prunusmume, Japanese apricot.Some nurseries train C. mas to ahigher-branched, single-stem tree (likeours at the UKREC Botanical Garden),but some of the most remarkable plantsaccentuate the bark characteristic fromtraining to a short-stemmed, multiplebranched(two to three) tree.In 1993, J.C. Raulston gave me aC. mas ‘Spring Glow’. Then in 1996, Igot another from NCSU plant breederDr. Tom Ranney. It is now a highlyregarded plant in the UKREC BotanicalGarden, due to its strategic siting at theemployee entrance to the Center. Ourplant suffered the indignity of a Bradfordpear tree falling on it during the 2009ice storm, but it was not injured by theApril 2007 freeze.C. mas can be found all across Kentuckyand has done very well in Kentucky landscapes.On a trip from Cincinnati toPrinceton on February 7, 2011, I foundC. mas ‘Spring Sun’ in tight bud at YewDell, Crestwood, KY; C. mas and C. mas‘Vidubetskii’ Red Star® in tight bud, withyoung wood a red color, while C. officinalis(a very closely related Japanese plant)and a C. mas variegated sport crackingbud with some floral parts exposed andshowing color at Bernheim Arboretum,Clermont, KY; and C. mas ‘Spring Glow’in bloom at the UKREC BotanicalGarden, Princeton, KY, which is inkeeping with Princeton’s new designationas a warmer zone 7 in the 2012 versionof the USDA Plant Hardiness Map.In addition to the previously mentionedwitchhazels and fragrant wintersweet,another early blooming woodyplant to look for is the plant-geekfavorite, the sweetly fragrant Prunusmume, Japanese apricot. 219Nursery Views / Spring 2012

Disease RxApril ShowersBring May...Disease?An Introduction to Water MoldsBy Nicole Ward, Ph.D., Assistant Professor of Extension, The University of KentuckyNursery Views / Spring 201220Springrains can create growingconditions that are devastatingto most landscapeplants. For example, excess water is responsible for adisorder called “wet feet,” which results from the suffocationof plant roots as waterlogged soil loses oxygen. However,suffocation is not the only injury to nursery or landscapeplants during rainy spring weather. Wet soils are favoredby a group of pathogens called water molds, or oomycetes,which cause a range of root and stem diseases.Water molds are found in most soils, but plant stressand high pathogen numbers can lead to severe disease.Common water molds such as Phytophthora and Pythiumcause root rots, stem rots, collar rots and damping offdiseases in both woody and herbaceous plants. Theyare also responsible for downy mildews and some foliarblights in upper plant parts.SymptomsSymptoms differ according to plant type and infectionsite. Root rot symptoms begin, not surprisingly, at theroots. However, because roots are concealed, the diseaseoften goes undetected until plants begin to decline or theupper plant parts wilt as a result root reduction. Diseaseoften begins during rainy spring weather, but it is typicallynot noticed until hot dry weather initiates wilting.Water molds can also cause above ground infections.These symptoms can range from yellow mottling ofleaves to water-soaked lesions on leaves and succulentstems. Woody stems and trunks may develop cankers justabove the soil line, often at a wound site. Cankers areusually dark-colored and may exude sap or “bleed.”Uniqueness of water moldsWater mold pathogens are very different from true fungi;they require free water to complete their life cycles. Initialinfections often occur during rainy spring weather as tem-peratures begin to warm. After infection, the pathogensrelease large numbers of “swimming” spores that move onfilms of water. This is the repeating stage that leads todisease epidemics if wet conditions continue. Spores arespread by splashing water and the movement of contaminatedsoil particles.Once established, water molds can produce survivalstructures that allow them to lie dormant during hot, dryseasons. Available water can reinvigorate these structures,and the disease cycle can begin again. Many water moldsoccur naturally in soils, and proliferation under wetconditions can be devastating to plants.Disease preventionusing cultural practicesMost water mold diseases can be prevented or managedusing cultural practices. Consider the management tipsbelow to prevent infections or to help manage infectednursery or landscape plants.3 Improve drainage.• Manage surface water.• Plant in raised beds.• Divert downspouts.• Use organic matter to improve internal drainage.• Limit irrigation.• Manage nursery runoff from infested areas.3 Disinfest tools, containers and greenhouses toeliminate spread.• Commercial sanitizers are available.• 10% Lysol® concentrate and 10% bleach are alsoeffective. Bleach is corrosive on metals, so rinsetools well before storage.3 Dispose of infested potting media.• Do not reuse contaminated soils.3 Destroy infected nursery and greenhouse plants assoon as possible.• Do not compost infected plants.

Fungicides must bespecifically labeled for oomycetes. Select fungicides thatcontain one of the active ingredients listed below. Efficacyof these fungicides is dependent on plant and pathogentype; read labels carefully.Fungicide active ingredients effective against watermolds include:• Azoxystrobin (Heritage)• Cyazofamid (Segway)• Etridiazole (Terrazole, Banrot)• Mefenoxam (Subdue)• Propamocarb (Banol*)• Phosphorus acid (Alude,Agri-Fos)* Not for use in residential landscapes,for commercial use only.See our fungicide guides PPFS-OR-W-14 and PPFS-GH-3 atwww.ca.uky.edu/agcollege/plantpathology/extension for moreinformation concerning fungicideuse, or contact your local UKExtension agent for assistance. 221Nursery Views / Spring 2012
