Webcasts focus on mop top virus and leafhopper control in potatoes
Pesticides are a critical tool in the management of insect pests and diseases, and they are the focus of the latest three Focus on Potato webcasts, which discuss the value of pesticides, the management of mop top virus, and the management of the aster leafhopper, a key vector of purple top disease.
Through his webcast titled “The Value of Pesticides,” Jeff Miller, president and CEO of Miller Research, helps users better understand the value of pesticides and their importance in the production of a healthy potato crop. Much information on the Internet focuses on the perceived risk of pesticides and largely ignores the benefits. Miller helps bring balance to users’ viewpoints by providing a general overview of the regulation and benefits of pesticides and the value they add to our society.
In “Potato Mop-Top Virus: An Emerging Problem in Potato Production,” Jim Crosslin, research plant pathologist at USDA Agricultural Research Service provides consultants, growers, and other practitioners in the potato growing regions of the U.S. with important information on potato mop top virus, which has been reported relatively recently in several areas of Canada and the U.S. and is increasing in importance in these regions. This webcast illustrates the various types of symptoms produced by PMTV and provide some guidelines for management of this soil-borne virus.
“Phytoplasmas in Potatoes“ by Ian MacRae, Extension entomologist at the University of Minnesota helps producers and agricultural professionals in potato producing areas recognize and manage the phytoplasma disease purple top in potatoes. In this presentation, the biology of the phytoplasma causing Purple Top and its insect vector, the aster leafhopper, are discussed as well as potential management of the disease in potato production. The disease, its symptoms and impacts are reviewed and the epidemiology resulting from the life history, distribution and movement of the vector-pathogen complex is presented.
These three presentations are open access through May, 2014.
