Using insects to control invasive weeds on pasture

Houndstongue biocontrol project in B.C. has been highly successful

Once invasive plants reach a point of domination, elimination is generally not feasible. Land managers sometimes turn to biologic control, a last resort for reducing a widespread weed’s populations to below an economic or environmental damage threshold. Eradicating the weed may be impossible, but biocontrol agents may reduce it to manageable levels. Since 1951, 82 […] Read more

Using an invasive weed to help fill the feed gap

When feed is in short supply, producers may want to harvest kochia.

For Prairie cattle producers looking for alternative feed sources this year, one possibility may be kochia. Kochia is an invasive weed, often seen growing on marginal land or tumbling across the Prairies. It’s a prolific seed producer, growing in saline soil and in arid or semi-arid conditions. A recent news release from Agriculture and Agri-Food […] Read more


Farming insects may solve one problem, create others

Rome | Thomson Reuters Foundation — Insects have great potential as an alternative source of protein, but further research is urgently needed before mass production begins in order to avoid environmental disaster, Swedish researchers warned Monday. There is currently an “overwhelming lack of knowledge” on basic questions such as suitable species, their housing and feed […] Read more

Danger stalks spring pastures

Vet Advice with Dr. Ron Clarke

Every spring and summer, livestock producers incur losses as a result of poisonous plants. Acute deaths often go undiagnosed. The more than 200 poisonous species of plants on Canadian range cause chronic illness and debilitation, decreased weight gain, abortion, birth defects, poor reproductive performance, and photosensitization. Some poisonous plants are nutritious when eaten in small amounts, […] Read more

Invasive weed species can affect both pasture and profit

Burdock is an invasive plant that causes problems for livestock and crops, and is generally considered a noxious weed. The tall burdock plant, a native of Eurasia, is a biennial, which means it lives for two growing seasons. The first year, it merely grows leaves and accumulates food reserves in its roots, like a carrot. […] Read more
