1. With phosphorus, ultimately the form you apply is less important than the amount you apply. Crop nutrition specialist Rigas Karamanos used the graph below to show the chronic under-application of P year after year…

Cover crops provide ground cover to avoid leaving fields bare. They provide weed competition, take up excess moisture, tie up nutrients at or near the soil surface so they’re not lost, and improve salinity. Nitrogen-fixing cover crops can increase soil nitrogen levels. Grassy cover crops act as “green manure”. All cover crops can reduce wind and water erosion of soil…

While it’s too late to spray effectively, growers and agronomists can check fields for the presence and population of winter annual weeds before the snow flies. This information can help with spring pre-seed burnoff and crop rotation planning…

Verticillium wilt was found in a canola field in Manitoba in 2014, and a survey of approximately 1,000 fields across Canada is underway this summer and fall…

While swathing or straight combining, keep an eye out for weed escapes. Unless they are an obvious sprayer miss or are weeds not well controlled under the herbicides used on the field, they could be herbicide resistant weed patches…

Growers considering a pre-harvest glyphosate cannot apply it to canola (RR or non-RR) until seed moisture drops to 30% or lower. This roughly coincides with 30% seed colour change. Spraying earlier raises the potential for glyphosate residue in seed. Pre-harvest glyphosate will kill green weeds and even out the non-RR canola for straight combining. Group-14 Heat can now be used…

When it comes to maintaining Canada’s reputation as a high quality canola supplier, everyone in the canola value chain has an important role to play…

Crop staging comes into play for herbicide, insecticide and fungicide timing. So crops with plants at various stages — some at flowering, some barely at the bud stage, for example — present a challenge when deciding when to spray…

Combining pest control operations to save trips over the field may seem like good economic sense, but consider the following when making this decision…
