Summary of key results – “Herbicides are certified to function in a wide range of situations, so I didn’t anticipate to see a significant variation in effectiveness across the various application times. But I quickly saw that early morning application was frequently the least reliable of any timing “Coles explains.
Growing up in southern Alberta, it is practically ingrained in our culture to get up really early to spray in order to beat the wind, so I found that particularly intriguing. The project’s findings, however, indicate that the early morning application time frequently reduces herbicide efficacy.” In both the burndown and in-crop trials, midday was often the most effective time, followed by midnight.
Coles explains, “Since night spraying was often more successful than dawn spraying, night spraying might be a viable alternative when daytime spraying possibilities are limited.” Liberty and Roundup (Vantage Plus Max II) performed well for canola at lunchtime and poorly in the early morning.
- He remarks, “I was astonished that Roundup had such a large influence on time of day.
- It is well knowledge that Liberty must be sprayed in the heat of the day in order to be effective as a contact herbicide, since it requires the heat to become active.” Wheat and peas have a somewhat different narrative to tell.
“We did not observe nearly as significant a link between wheat herbicides and time of day; they performed best under most settings. Nighttime applications of the pea herbicides Odyssey and Select seemed to be more effective.” Therefore, according to Coles, wheat should be sprayed in the early morning, canola in the middle of the day, and peas at night.
- In general, broadleaf weeds were more susceptible to the impact of time of day than grassy weeds.
- Regarding weed management, Coles cites an additional intriguing finding: “Liberty is notorious for its ineffectiveness against grassy weeds, yet when sprayed at night, its grass kill improved.
- This sort of information might prove useful in the fight against herbicide-resistant weeds.
Suppose you have Group 1 and Group 2 resistant wild oats and you have few choices left to eradicate them. The nighttime application of Liberty on Liberty canola might help keep these resistant wild oats under control.”
