Black Cutworm Alert for Late-Planted Fields in Ontario

Yesterday, I checked a variety trial near Alliston that was planted late, on May 27. There was a moderate to high population of small black cutworms in the plots of late varieties, those that still had green foliage. Although the worms were small, there were also tubers with feeding damage. Small larvae of the black cutworm feed on the foliage in the evenings and remain buried in the soil near the plants…

Digging of the Fresh-Market Crop Has Begun Near Leamington, Ont.

Things looked very different across the province from July 22 to 26 depending on the area.  Digging of the fresh-market crop has started near Leamington, Ont. Quality and size look good. Growers are digging the earliest planted fields in the Simcoe-Delhi region, but the area is dry. “Harvest has started for us and the crop looks good. We need some rain because harvesting and irrigating are not a great combination,” said Joe Lach,…

Scientists Discover Key Plant Virus-Insect Virus Interaction

By Aaron J. Bouchie Aphids and the plant viruses they transmit cause billions of dollars in crop damage around the world every year. A Cornell-led research team is examining the relationship at the molecular level, which could lead to new methods for controlling the pests. A group led by Michelle Heck, research molecular biologist at the USDA Agricultural Research Service (USDA-ARS) and Boyce Thompson Institute, used recently developed small RNA sequencing techniques to better…

New Tools for the CPB Toolbox

A study being conducted by researchers at Agriculture and Agri-Food Canada’s London Research and Development Centre could soon provide Canadian potato growers with new insight on how to fight one of the industry’s most troublesome pests — the Colorado potato beetle. The five-year study is officially known as the Development of Regional Management Strategies and Decision-Making Tools for Control of the Colorado Potato Beetle. Work on the project began this past summer…

Researchers Go Toe-to-Toe with PCN

Although extremely rare in Canada, potato cyst nematodes (PCN) are such a serious risk to potato production and trade that the Canadian Food Inspection Agency (CFIA) has strict surveillance and quarantine protocols. When PCN was discovered in Quebec in 2006, the CFIA immediately implemented quarantine measures for the affected fields. As well, the agency took other important steps, including working with Agriculture and Agri-Food Canada (AAFC) and other stakeholders to identify research…

New Prospect for Wireworm Control

A few years ago, Todd Kabaluk was given some fuzzy wireworms. That might not sound like an auspicious gift, but Kabaluk is a research biologist in integrated pest management with Agriculture and Agri-Food Canada (AAFC). He was immediately interested. As it turned out, these fuzzy wireworms were the first step on the path toward a new possibility for controlling wireworms. Wireworms are the tough-to-control, soil-dwelling larvae of click beetles. AAFC has found…

BASF Launches Critical Insecticide for Use in Canadian Soybeans and Potatoes

Canadian farmers have a new tool to protect their soybean and potato crops in 2019 with the launch of BASF’s Sefina™ insecticide. Sefina utilizes a unique mode of action, Group 9D active ingredient Inscalis™, to quickly halt aphid feeding, reducing production losses and virus transmission. In research and commercial trials across Canada and the United States, Sefina showed extended control of up to three weeks against additional aphid pests that have, over time, developed resistance to other insecticides. “Canadian…

Seeking a Whammy for Wireworms

“We have estimated wireworm costs Prince Edward Island’s potato industry more than $10 million per year in damaged product, crop protection products, crop insurance claims, and costs associated with rotation crops to battle wireworm,” says Ryan Barrett, research coordinator with the P.E.I. Potato Board. “While research by Agriculture and Agri-Food Canada researchers, such as Dr. Christine Noronha and Dr. Bob Vernon has provided growers with more tools to battle this pest, it…

Colorado Potato Beetles Wanted

Dr. Ian Scott, a research scientist with the London Research and Development Centre at Agriculture and Agri-Food Canada, is conducting a survey of Colorado potato beetle susceptibility levels to registered insecticides (neonicotinoids, diamides and spinosyns). What does he need? He is looking for approximately 150 beetle adults (a minimum of 75 adults or large larvae are acceptable) per sample. If you have a few you can spare, please contact Dr. Scott and…
