John Guelly tweeted this photo during this year’s harvest with the warning: “When ur out swathing, spraying or harvesting, keep an eye out 4 patches that look brown & dead like this.” Although clubroot wasn’t the cause in this case, taking a proactive approach is critical to managing the disease, which is continuing its relentless march across the province.
