Farmers are being encouraged to check for verticillium stripe in canola

Aug 22, 2023

Verticillium Stripe is a fungal disease that was first discovered in Canadian canola crops in 2014, the disease causes lodging and yield loss in canola.

Courtney Boyachek, an agronomy specialist with the Canola Council of Canada says it's a soil-borne disease.

"Meaning that, it overwinters in the soil and then it germinates in the soil in the Spring and then the plant uptakes it around flowering."

She says in order to identify the disease producers will want to cut the stem of the canola plant off right at the root.

"It'll just be that grayish Starburst in the cross-section, kind of around 60% seed color change. You'll be able to see a really definitive line up the middle of the plant - where half of the plant is going to start dying off and half of the plant is still going to be thriving. A couple of other things - the epidermis of the plant (the stem tissue) is just going to start peeling away like wallpaper, underneath that once you peel that off, you'll be able to see little microsclerotia. It kind of looks like someone took a pepper shaker and shook pepper all over the stem."

Video: Western Canadian Agriculture: Hard Times Made the World's Best Farmers

Western Canadian agriculture produced the most advanced farmers in the world not through abundance but through adversity. The crow rate fell. The wheat price went nowhere. The brown envelopes stopped.

When the subsidies disappeared, the bad farmers left and the good ones stayed. And the ones who stayed could not just grow wheat anymore. They started growing lentils and canola and peas and flax and faba beans. They built crop rotation. They got serious about agronomy because there was no government backstop. That process produced the Western Canadian agriculture Dennis Bulani describes in this clip: the most advanced, most educated farming culture in the world.

His contrast with Iowa corn and soybean farmers is sharp. At a DeKalb farmer meeting in Okoboji, Iowa, he asked what crop rotation they ran. Beans on corn stubble, corn on bean stubble. How do you fertilize? The co-op agronomist handles it. Have you considered other crops? No need. We make so much money on corn and soybeans. Western Canadian agriculture was never allowed that comfort. And now those Iowa farmers are watching soybean markets lock up with China and corn prices slide, and they do not have the agronomy knowledge or the research base to pivot. Western Canadian farmers adapted on a dime because they had done it before.

Dennis also makes the case that Western Canadian agriculture keeps adapting in real time. Low commodity prices over the past year have pushed growers to look seriously at precision spot-spray technology. He knows a neighbor who bought a sprayer with the seeing-eye system and sprayed only 80 out of 320 acres. As a chemical retailer Dennis acknowledges that will affect his sales. He supports it anyway, because if it advances Canadian agriculture and makes farmers money, that is a good outcome.

The lesson Dennis draws from the tale of two farms: continuous improvement is the only durable strategy. When canola was $22 a bushel some growers went to Arizona instead of the Crop Production Show. When the price came down those same growers came back to the research and the discipline. Products do not go on Rack Petroleum's shelves unless they pass a replicated trial first. That is what Western Canadian agriculture built through hard times: farmers who do the work whether the times demand it or not.
