Ontario's hot weather keeps late blight in check but some growers are seeing sunburnt stems and heat stress in their potato crop. 
The Pest Management Regulatory Agency (PMRA) completed its re-evaluation of mancozeb and found the continued registration of products containing mancozeb acceptable for foliar application to potatoes in Canada.
The results from Ontario spore traps, in Alliston, Leamington, Simcoe-Delhi, and Shelburne areas, returned negative detecting no late blight spores, according to Eugenia Banks’ latest potato update.
Agriculture and Agri-Food Canada researchers in Fredericton, N.B. are exploring environmentally friendly solutions to manage Potato Early Dying complex (PED), a disease that is limiting yields in many potato fields in eastern Canada. PED is a disease complex caused by a combination of a fungal disease (Verticillium wilt) and root-lesion…
Potato virus Y (PVY) affects both yield and the quality of the crop, making it one of the most dangerous diseases faced by commercial potato producers. Spread by aphids and through infected seed lots, PVY has been managed with varying levels of success by Canadian growers for many years, but…
Potato industry stakeholders from across the United States gathered in Bangor, Maine in November 2017 to deliberate on Dickeya, the aggressive disease that’s devastated thousands of potato acres in the U.S. since its first major outbreak in 2015.
As spring arrives, potato growers are concerned about Dickeya, and Eugenia Banks, the Ontario potato specialist, has some points of interest to share. Potato seed infected late in the season with Dickeya (new blackleg) usually does not show symptoms in the field before harvest nor in seed storages. This is because…
Syngenta Canada Inc. has announced Orondis Ultra fungicide is now available in a premix formulation for added convenience.
For the first time, evidence of the zebra chip pathogen has been found in potato fields in southern Alberta.An infected potato psyllid insect carries the Lso (Candidatus Liberibacter solanacearum) pathogen that can cause zebra chip disease in potato crops.Zebra chip has affected potato crops in the U.S., Mexico and New…
All the isolates of late blight -Phytophthora infestans tested were US-23 for 2017. No new late blight incidence has been reported in the last week, which has generally been dry, warm and windy. The 7-day DSV accumulation for late blight risk has been essentially minimal. Harvest has begun in many…
Alberta's potato industry is worth more than $1 billion to the province's economy. But it's threatened by a tiny bacterium that causes zebra chip disease, which has already affected crops in the United States, Mexico and New Zealand. This year, a Lethbridge scientist reports, it hasn't shown up in the province."We…
Late blight has been confirmed in Manitoba from Rural Municipality of Norfolk Treherne in South Central potato growing region in Manitoba. The region had heavy rains last week in the area. Leaf spot infections appear to be scattered close to the irrigation pivot. The infected leaf spots have sporulation and…
A virologist with Agriculture and Agri-Food Canada (AAFC), in collaboration with breeders, has developed a way to speed up marker-assisted selection in the effort to identify potato virus Y (PVY) resistant material. The method – known as high-resolution melting markers, or HRM markers – has been used in other breeding…
There’s no current technology to detect acrylamide precursors quickly and without destroying the spud, but a new technique developed by Lien Smeesters from the University of Brussels might help weed out potentially toxic potatoes before they even go to market. In Smeesters’ design, a laser uses infrared light to detect…
With planting season just around the corner, researchers at Agriculture and Agri-Food Canada are reminding home gardeners to take precautions to prevent the infection and spread of late blight. Planting clean and disease-resistant seeds is the best way to prevent the spread of late blight to other gardens and potato…
