Corn smut infection has its roots in the genes

German researchers find five genes that the Ustilago maydis fungus uses to manipulate a corn plant’s signalling pathway

Researchers at Germany’s University of Bonn have identified five genes in the fungus Ustilago maydis that cause the disease corn smut. Corn smut causes kernels to swell into tumour-like galls whose tissues and texture are like mushrooms. They can grow from about six inches to the size of a child’s head. The galls are made […] Read more

L. capsica is related to a family of bacteria called Liberibacter, of which there are nine known species. One species infects potatoes and three are associated with the deadly citrus-greening disease, also known as huanglongbing. | File photo

Scientists watch rapidly mutating crop-infecting bacteria

Researchers at the University of California, Riverside, are focusing their attention on a recently identified, rapidly mutating bacteria called Liberibacter capsica, wary that it may become as harmful to crops as some of its relatives. L. capsica is related to a family of bacteria called Liberibacter, of which there are nine known species. One species […] Read more

Producers who market their beef as grass-fed must make sure that forage quality is high when cattle are gaining weight. | File photo

Grass-finished beef all about forage

A growing number of cattle producers are marketing grass-finished beef. The challenge, especially in a northern climate, is having high quality forage in the months that cattle need to gain weight and finish. Experts say it’s important to have genetically efficient cattle that do well on grass and to feed energy-dense forages in the finishing […] Read more


The fall corn harvest was a time to see who could polish off the most cobs.  |  Alma Barkman photo

Corn season brings fond memories

The generosity of a neighbour at harvest time meant this farm family was able to gather up all the cobs they could eat

By late autumn I had eaten my fill of toasted tomato sandwiches and bowls of cucumbers chopped up with sour cream and onions, but I never got enough corn on the cob, and so I looked forward to the yearly corn feed. It seemed to me that it always happened rather spontaneously. About the time […] Read more

Researchers at Emory University have found that streptomycin antibiotic spray used in fruit orchards can decrease a bee’s foraging choice accuracy and increase its avoidance behaviour.  |  Getty Images

Antibiotic spray affects bumblebee cognition

Researchers determine that a common treatment for fire blight in fruit orchards can hurt the pollinator’s foraging ability

In recent years, the use of streptomycin antibiotic spray has increased as orchard farmers fight a rise in plant bacterial infections caused by pathogens such as Erwinia amylovora. Fire blight can turn blossoms and shoots of apple and pear trees black, making them look like they were scorched by fire. Citrus greening, also known as […] Read more


The composition of the bumblebee community will likely continue to change as the climate warms, with most species’ ranges shrinking and few species increasing.  |  Getty Images

Climate change hits bumblebees as world warms

Researchers find that 37 of 46 species showed greater declines or less responsive increases due to rising temperatures

Recent research from Simon Fraser University in Burnaby, B.C., suggests that the greatest negative influence bumblebees face from climate change are changes in temperature, which could affect the insects even more than precipitation changes or changes in the flower types. The study focused on the historical changes driven by climate change and rising temperatures over […] Read more

Producers say that knowing the North American bison herd has widespread introgression of cattle DNA will allow ranches to manage genetics programs without worrying about cross-contaminating herds that were once thought to be clean of introgression.  |  William DeKay photo

Cattle genes in bison unable to hide

Previous research found cattle genes in most bison, but advanced genomics discovers more widespread presence

According to a new study by scientists at Texas A&M University, all bison in North America carry multiple small, yet identifiable regions of DNA that originally came from cattle. The research confirms there are, in fact, no purebred bison on the continent. “I did genetic bison research 20 years ago and, at that time, it […] Read more

Turkey Red wheat proved to be an invaluable travelling item for Mennonite farmers when they began planting crops on their new farms.  |  Alma Barkman photo

Farmers packed prized wheat on trip to their new home

Mennonite families often brought trunks full of Turkey Red wheat with them when they emigrated to North America

In a big, red hip-roof barn on a Saskatchewan farm there once stood a sturdy homemade trunk. It had contained some of the family belongings when Dietrich and Elizabeth Barkman homesteaded in 1906 in the Flowing Well district of the province. Emptied of its contents, the trunk was stored in the barn for decades. My […] Read more

New school term starts with trip to the bookstore

The boredom of summer on the farm could only be broken by the return to school, and then something better happened

By the middle of August, the swimming hole was no longer inviting, having shrunk in diameter and depth as the little creek that fed it gradually decreased in volume. Harvest preparations were in full swing, meaning my mother no longer had time to go for long walks with me out the country lane. Friends with […] Read more

According to Agriculture Canada, global climate models confirm the future will be warmer with more extreme weather events. Climate records show that the Earth has been heating for the past century and 17 of the 18 warmest years have occurred since 2001.  | File photo

Ag adjustments urged to mitigate climate change

U.S. researcher says big shifts are needed in what and how food is grown to keep agriculture sustainable and resilient

Farmers continue to consider ways to adapt agricultural practices to mitigate the consequences of climate change on their operations. According to Agriculture Canada, global climate models confirm the future will be warmer with more extreme weather events. Climate records show that the Earth has been heating for the past century and 17 of the 18 […] Read more
