It’s evolving right into a slightly odd 12 months for pre-harvest weed control in components of Western Canada as a return of some moisture has meant sprouting swaths, and monster weeds. In Ontario, an accelerated season means loads of farmers are making the dry-down determination on edible beans this week.
From pre-harvest weed control, to swapping to a desiccant, and on to post-harvest choices, this episode of The Agronomists will get solutions from Rob Miller, with BASF, and Tammy Jones, of Corteva.
Catch a brand new episode of The Agronomists each Monday evening at 8 pm E!
- We get a crop replace from each Miller (close to Guelph, Ont.) and Jones (close to Carman, Man.)
- To spray or to not spray? Desiccant, that’s. Should you’re considering when it comes to your edible beans, try our newest Edible Bean College episode
- Canola sprouting within the pod? Swathed canola re-flowering? Now we have expletives for that
- Clip #1: Soybean College: Pre-harvest burndown choices for a fast-moving crop
- Examine along with your processor for allowed product use
- The distinction between dry-down (desiccant) versus weed control
- Spraying a 4 foot tall weed proper now just isn’t weed administration, it’s now thought of dry-down
- Are there numerous “escaped” weeds? Contemplate that they is perhaps resistant
- The debate to go away glyphosate within the tank combine
- Pre-harvest interval — go together with the herbicide within the tank combine with the longest PHI
- PHI for canola: time between spraying and reducing, not spraying and placing it within the bin
- Clip #2: Wheat College: Making the proper alternative for fall weed control
- Don’t rely solely on spring control, a pre-harvest go is a good suggestion in some circumstances
- Winter annuals? Weeds that may germinate within the fall?
- The fall window may be a good way to get forward of spring — a number of alternatives, however challenges as nicely
- Winter does care for some weeds for us, however some thrive and want that vernalization
- Some weeds develop into a small goal for herbicide after the mix goes by
- Even unfold of chaff issues; use open falls correctly
- When to spray out regrowth versus simply leaving it for the frost, particularly in a 12 months when moisture is restricted
- Snirt (snow plus filth) just isn’t good
- Naked soil is undesirable, so take into account planting one thing (if you happen to’re within the east), Miller recommends oats
- Kochia after harvest, regrowth, seed manufacturing… Go Jones Go
- Grazing? Be careful for nitrates
- Kochia seed doesn’t final within the seedbank for very lengthy, most of it germinates the following 12 months. Lamb’s-quarters of redroot pigweed, and even waterhemp, have extra sturdy seed coats
- Again to frost for a second, it is dependent upon the weed
- Clip #3, which we didn’t truly get to throughout the present: Weed control in a dry 12 months and the chance of carryover
- Herbicide carryover: rainfall in-season plus soil texture (clay particles will bind pesticide molecules, greater OM means greater microbial biomass, which course of stated pesticide molecules)
