Horticulture & Landscape Architecture > Extension > Commerical Nursery and Landscape Program

The Purdue University Commercial Nursery and Landscape program strives to make the industry in Indiana, the Midwest, and the United States more profitable, sustainable, effective and efficient, while increasing the quality of life for the owners, employees, and the general public through education, research, and outreach programs. The Department of Horticulture and Landscape Architecture, with the assistance of Purdue University Extension, aides in facilitating these endeavors. Being a leading land grant institution, extension and outreach programs are designed to facilitate the advancement of agricultural industries, including the Nursery and Landscape Industry. We will commit to the industry to develop and maintain effective educational programming and research that will be relevant and productive for the industry’s needs. We always welcome feedback to become a more efficient resource for the Nursery and Landscape Industry.

New Resources Available for Emerald Ash Borer and Pollinator Safety

Cliff Sadof, Department of Entomology, Purdue University

We are happy to announce two new tools give the latest information about two hot topics: emerald ash borer and pollinator safety.
Emerald Ash Borer Self Study Course
Self study courses for the Green Industry and Master Gardeners are now available at the following on our website. 
Each course uses 100 slides to guide the student through the history, biology and management of emerald ash borer.  We review the latest tools, for diagnosing EAB and assessing tree health.  We also provide clear suggestions on how to come to an effective management decisions.  These both draw heavily on insecticide recommendations that were revised in June 2014 (  to include how to effectively apply imidacloprid, dinotefuran, azadirachtin and emamectin benzoate. 
Students who can pass a 50 question quiz can print a certificate to demonstrate that they have received special training about EAB.


New Neonicotinoid Pollinator Website available for the Green Industry.
Doug Richmond and I have developed a mobile friendly website to help you answer questions you may have about how the use of neonicotinoid insecticides, like imidacloprid, dinotefuran, acetamiprid can affect pollinators. ​ We provides specific fact sheets to  help you safely protect plants from pest, while minimizing harm to pollinating insects. We also provide links to other resources to provide a science based background about the controversy. 


Indiana Nurseries: Time is running out to have your voices heard!

Kyle Daniel, Commercial Nursery and Landscape Outreach Specialist
Department of Horticulture and Landscape Architecture, Purdue University.

More than likely you have witnessed the increased awareness about invasive species, particularly invasive plants, over the past few years.  Fairly or unfairly, the Green Industry is often on the defensive in the discussions about invasive plants.  The modes of introduction are many, including through the ornamental trade.  It is very important for your operation to be well versed in the terminology surrounding invasive plants.  There are many terms associated with invasive species, including alien, non-native, introduced, and exotic, relative to invasiveness.  All of these terms are synonymous in relation to invasive species.  Not all introduced species are invasive and not all natives are non-invasive. 

The Indiana Nursery and Landscape Industry should be aware of coming legislation to invasive plant species within the state.  Plants that will have significant impact to the industry are to include, Pyrus calleryana (callery pear), Acer platanoides (Norway maple), and Euonymus fortunei (wintercreeper).  With Phil Marshall and Megan Abraham of the Indiana Department of Natural Resources leading, we are conducting a cost analysis to Indiana nurseries in order to determine the economic impacts in prohibiting the sale and movement of specific species.  We have sent a survey to all nurseries throughout the state and the IDNR has approached the largest nurseries (>25 acres) to gather data.  At the Indiana Green Expo on January 22nd, there was a listening session that allowed for feedback to the committee (Fig.1).  Though this session was helpful in moving forward, we need as many nurseries to contact us as soon as possible with feedback and economic impacts of their operation so that the ‘whole picture’ can be gathered. 

There are viable alternative species that can be used in place of the three plants listed above.  The Purdue Green Industry Working Group, with the assistance of the Indiana Nursery and Landscape Association, business owners, IDNR, and The Nature Conservancy, is currently working on a list that is viable for nurseries, landscapers, and homeowners.   We must remember that education for the end-consumer is key to this venture.  Educating your customers can assist to minimize the detrimental effects to your bottom line. 

Remember to contact Kyle Daniel at as soon as possible with feedback so that we can send to the committee charged in making this process as smooth as possible for your nursery and/or landscape company.
