The neonic debate: science or sensationalism?

Laying the blame for a collection of environmental issues at the feet of a  single technology is very convenient, but hugely overly simplistic

By Pierre Petelle August 5, 2014

Bold, apocalyptic headlines make for great front-page news stories, there’s no question. Unfortunately, when it comes to highly complex and scientific issues, these kinds of headlines usually do a disservice to the topic at hand. Scientific research is filled with intricacies and rarely yields answers that can be conveyed in a single headline. Far too

Mink ranchers get reprieve from depressed market

The federal government has extended the deadline for repaying cash advances

By Ron Friesen July 30, 2014

Canada’s financially beleaguered mink producers received a bit of good news last week when the federal government extended the deadline for repaying their 2013 cash advances. Producers now have until June 1, 2015 to repay their Advance Payment Program (APP) cash advances instead of September 30, 2014. The move provides some relief for producers who

This filed of canola is at the 50 per cent bloom stage. The optimum time to apply a fungicide to protect canola from sclerotinia is at 20 to 30 per cent bloom, but it can be applied up to 50 per cent bloom. photo lionel kaskiw, mafrd

Tools to assess sclerotinia risk in canola

The risk was high last week, but it might not be this week

By Allan Dawson July 18, 2014

The sclerotinia risk was high in most of Manitoba last week, but it may have changed this week and the risk could be different a week from now, says Manitoba Agriculture, Food and Rural Development (MAFRD) oilseed specialist Anastasia Kubinec. That’s why it pays farmers to assess the risk to their own canola crops before

Plants can hear the difference

They respond differently to vibrations caused by  chewing insects than to wind

By University of Missouri-Columbia July 17, 2014

University of Missouri-Columbia – Researchers at the University of Missouri-Columbia have found plants can not only tell the difference between the sound waves caused by insects chewing and wind but they respond with more defences. ‘We found that feeding vibrations signal changes in the plant cells’ metabolism, creating more defensive chemicals that can repel attacks

Beef 911: Hyperthermia (overheating) in farm animals

Calving during hot weather with no shade is a recipe for trouble

By Roy Lewis July 15, 2014

Every year during the first few hot days of summer we hear media warnings about leaving pets unattended in closed vehicles, where temperatures can rise to over 50 C. We often don’t realize how susceptible livestock are to the same condition. Many a farmer or veterinarian has been fooled by symptoms resembling a toxemia or

Manitoba arthropod populations expanding

Although rare in Manitoba, bovine anaplasmosis can be spread by wood ticks

By Shannon VanRaes July 15, 2014

They only have eight tiny legs, but ticks are on the move in Manitoba and across the Prairies. “They’re moving north for sure,” said entomologist Kateryn Rochon, noting the arthropods travel with their hosts, including deer, birds, rabbits and other animals. The University of Manitoba professor is tracking the movement of the American dog tick

Ergot contaminated feed is causing a wide range of easily misdiagnosed herd health problems in Western Canada

Long, brutally cold Prairie winters could be masking signs of a serious toxin lurking in livestock producers’ feed bins, a University of Calgary veterinary professor warned feed and livestock industry officials recently. Dr. Eugene Janzen, assistant dean of clinical practice, said he was initially perplexed in the winter of 2013 when he observed Alberta feedlot

Targeted deworming can help maintain herd health

Treating horses that are ‘heavy shedders’ can reduce total parasitic infestations on the farm by up to 80 per cent

By Carol Shwetz July 9, 2014

Most horse owners are keenly aware of the importance deworming plays in the health of their horses. Veterinarians, pharmaceutical companies and extension programs have done an exceptional job at promoting frequent scheduled dewormings. Yet recent science about the biology of equine parasites has found that using more deworming compound does not necessarily result in a
