Drought brings up questions of herbicide carryover risk for 2022 — and re-cropping support

[ad_1]

Not solely is there a lot of risk of crop damage resulting from herbicide carryover in Western Canada subsequent 12 months, there are additionally a lot of questions being requested by farmers about whether or not the state of affairs might or ought to have been dealt with in another way.

Because of the lack of rain to interrupt down energetic substances in sure merchandise, BASF issued an pressing discover to Prairie farmers this previous week, warning towards planting canola, durum wheat, or canary seed in fields the place particular imidazoline-based herbicides — primarily Solo, Viper, Odyssey and Pursuit — have been utilized in 2021.

Each time there’s an prolonged dry climate sample, growers ought to attempt to be conservative in selecting herbicides with the shortest potential carryover, however “it’s human nature to hope for the best,” says Clark Brenzil, weed specialist with Saskatchewan’s Ministry of Agriculture, sharing a third-party perspective on the herbicide carryover situation within the interview under.

Some producers which can be having to vary cropping plans for subsequent 12 months are questioning why the pressing message, in addition to new data on which crops won’t be supported, is barely being conveyed at this level within the rising season, properly after they utilized the aforementioned herbicides.

Brenzil says the timing of BASF’s discover is “probably as good as it could be.”

“It’s better that they (farmers) know now going into next season than after they’ve planted their sensitive crop that totally gets wiped out by the residue,” he says.

That being stated, Brenzil additionally believes issues brought on by Group 2 carryover ought to have been acknowledged earlier.

“I think it’s long overdue because I think we’ve had previous dry periods that have illustrated there’s a bit of a concern. I think the reason it’s coming out now is the dry conditions this past year were so extensive that it creates a very large risk for the company in question. So I think they’re trying to get ahead of it,” he says. “From that perspective, that’s good they’re preventing a potential disaster from happening next year.”

BASF shouldn’t be the one firm with merchandise that include carryover risk, notes Brenzil, referring to the energetic substances in different residual merchandise from FMC, Bayer, and Corteva. “I think we have to realize that this company is not alone, and that it’s not the only one that has residual products that producers are going to have to watch for.”

With canola being included on the checklist of cropping choices that BASF won’t be supporting in sure eventualities for 2022, some farmers are feeling as if the goalposts have been shifted on them after the product was utilized.

“For Odyssey, that one you weren’t supposed to re-crop to canola anyway. So I know that’s something that producers try every once in awhile, and not always are they successful. The canola and flax were added fairly late in the life cycle of Solo, so it’s probably one of the most sensitive re-cropping options you could have for that product,” explains Brenzil.

One other query that has come to the forefront is whether or not or not BASF is solely being too cautious. Brenzil says possible no, merely resulting from how excessive this drought has been.

“Essentially, the western half of Saskatchewan has had less than 100 mm of rainfall in those months of June, July, and August,” he notes, which isn’t practically sufficient for the soluble charge of many of these merchandise.

Hearken to the interview above for extra from Clark Brenzil on the components contributing to herbicide carryover risk and the pressing discover issued by BASF.
