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… -
If good moisture has increased yield outlooks and nitrogen may not be sufficient, top dress applications should occur before the 5-leaf stage of the crop… -
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. Get a second opinion when necessary. You need to know what caused a problem before you can take effective corrective action… -
When scouting, take time to check the plant stand. Look for blank areas and also look for thin areas. The plant… -
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…
