World Review

The Netherlands Phytopathologists at Wageningen University in the Netherlands have discovered a new mechanism that increases the resistance of potatoes to Phytophthora infestans, which causes late blight in potatoes. The new kind of resistance is based on the protein LecRK-I.9 and operates on the outside of the plant cell. This is new, because the resistance used so far to help potatoes withstand Phytophthora recognizes unwanted intruders in the plant cell.  But this…

Eye On The Nation

Quebec By Clement LaLancette, General Manager Federation des Producteurs de Pommes de Terre du Quebec In 2010, 2011 and 2012, Quebec potato producers participated in a project to determine the efficacy of using the Miléos forecasting model to control potato late blight disease (Phytophthora infestans), compared to preventative systematic fungicide treatments. The project was financed by the Canadian Agricultural Adaptation Program. The Miléos model was developed by Arvalis, a French vegetal institute,…

March Numbers for Canada’s storage holdings from the United Potato Growers of Canada are showing an increase from the same period in 2013. “In the East it’s basically the same as it was a year ago, and in the West it’s up significantly, almost 10 per cent,” says Kevin MacIsaac, general manager of UPGC. “That’s related to above-average yields to start with, in Manitoba and certainly in Alberta.” MacIsaac points to movement as…

Boosting Fertility Through Testing

New advances in tissue analysis of potato crops could give growers an early warning of nutrient deficits that could be impinging on yield potential — as well as allow them sufficient time to take remedial action, according to Jez Wardman, a plant nutrition specialist at fertilizer company Yara UK. “While soil analysis can help identify potential issues and plan fertilizer programs,” he says, “petiole or leaf tissue analysis is a far more…

Equipment and Technology Showcase

Foliar Fungicide Early Blight and brown leaf spot have recently become less sensitive to existing Group 11 and other Group 7 fungicides in North America, leaving potato growers with fewer effective options. Luna Tranquility, a fungicide already trusted by apple and grape growers, now offers potato growers an effective alternative to control these diseases as part of a responsible resistance management program. Bayer CropScience recently received registration for Luna Tranquility as a foliar…

Thinking Biorationally

In the battle against potato pests, what’s old is becoming new again. Biological pesticides, or biorational pesticides as they are also known, are gaining growing acceptance among farmers, despite the fact that biological pest control technology is anything but new. In fact, this type of pest control — that is, using ‘natural’ substances produced by Mother Nature to combat diseases and insects — is the oldest weapon in a farmer’s arsenal. “The…

Potato Mop-Top Virus

Potato mop-top virus, or PMTV, is a disease that is on the rise in the United States, says retired American plant pathologist Jim Crosslin. Since pathogens don’t respect borders, some potato experts believe there’s a chance PMTV could become an issue in Canada, too. While many potato viruses are transmitted by aphids or nematodes, PMTV is spread by spores of the powdery scab pathogen Spongospora subterranea. Powdery scab favours moist soil and…
