Herbicide performance is on a sliding scale depending on the weather. Cloudy days with highs of 10 C after a night near 0 C will tend to result in herbicide performance at the low end. Sunny days with highs of 15 C after a night of 3 C will provide improved control. Sunny days with highs of 20 to 25…

Weed control remains top of mind. Without good weed control, all other inputs — including fertilizer and top quality hybrids — cannot achieve the return on investment expected of them.……

Cool cloudy days after cool nights will result in lower herbicide efficacy than applications made in warm sunny days. Cloudy days don’t provide the photosynthetic activity required for many herbicides, including Group 10 glufosinate. And nights near freezing followed by days with highs that barely reach 10 C will not provide high metabolic activity required for best results from Group…

You maybe went to a field to scout for flea beetles, but take time to look around. Consider all possible causes when you notice uneven emergence, patchy growth and unthrifty plants.

Gophers can eat up large areas within a canola field. Strychnine baits and, in some jurisdictions, mix-it-yourself strychnine liquid is available for gopher control. Phostoxin is also registered for gopher control, but this is a restricted use product that requires a special permit for purchase and application…

Canola is quite susceptible to water logging and shows a yield reduction after only three days with wet feet. If only a small percentage of the field is lost, reseeding may not pay off — especially if that small percentage includes a bunch of pot holes all across the field. And wait to see how the crop recovers from saturated…
