Dr. Beckerman’s primary responsibility at Purdue University is to lead the plant pathology extension education effort in horticultural crops by developing and enhancing a close working relationship between the University, extension educators, and members of the fruit and ornamentals industries, and the developing hemp industry. There are two major approaches to managing plant disease in horticultural crops: Incorporating disease resistance, when possible, and utilizing fungicides, when necessary. The goal of my extension program is to enable commercial growers to effectively and sustainably manage both chemical (fungicide) and genetic (disease resistance) resources while protecting the environment. To this end, research in Dr. Beckerman’s lab includes:

 

As part of her extension program, she has developed (with Dr. Cliff Sadof, Entomology) a series of four apps, to assist homeowners in the diagnosis and management of landscape plants, and tomatoes.  these apps work for both the iOS and Android platforms.  For more information see www.purdueplantdoctor.com
