Wet soils cause an oxygen deficiency, which reduces root respiration and growth. Root failure reduces nutrient uptake, and plants will eventually die unless drowned areas dry out quickly…

Excess moisture can reduce soil nitrogen levels through leaching and denitrification. A top dress could address this. But excess moisture and other weather factors that set back the crop may also reduce overall yield potential, which means the crop may not take up as much nutrient anyway… -
The Canola Council, in collaboration with PAMI and the provincial canola grower commissions, is gathering information to help define best management practices for summer storage of canola. We do not have enough practical information to answer the question “How does the warm summer air affect the temperature, moisture and potential spoilage of cooled canola?” There was also no way to… -
Sock it to wind. A little wind is OK, but take measures to reduce drift (shown above). Herbicide timing is more important that waiting to achieve full coverage from a fine spray. Flea-ing to the stems. In windy and cool conditions, flea beetles may duck for cover and feed on stems. Take a look. This hidden damage can be costly… -
We have two maps from AAFC's Drought Watch site showing rainfall as a percent of normal. The top map is for the week of May 27-June 2 and the second is for June 4-10. Quite a difference… -
Here are the questions: 1. Growers have two key considerations when it comes to spraying — good coverage and drift management. What two objectives below will help you achieve good coverage while also reducing the drift risk? 2. Which situation is most likely to provide the greater economic return for a herbicide spray? 3. The best conditions for spraying herbicide… -
How do you spray weeds in a timely fashion when every day seems too windy? Too windy, according to the Guide to Crop Protection, is wind above 15 km/h. But we know that some operators will go with winds of 20 km/h and maybe a bit above. Here are tips to improve performance and limit the drift risk in wind… -
Applications made when cool cloudy days follow cool nights will result in lower or slower 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… -
High winds may force flea beetles off leaf tops and down to leaf undersides and leaf stems. Stem feeding could make the flea beetle situation worse, since it takes just a few bites on a stem to nip off a whole cotyledon or sever the stem. Stem feeding, if it’s happening on a lot of plants, has a lower control…
