Prairie broadleaf herbicides cleared for aerial use

If this spring should turn muddy, any cereal growers who may not be able to get at broadleaf weeds with a ground sprayer will have three additional Group 4 options for an aerial strike.

Dow AgroSciences announced last week it has picked up registrations for aerial use of Prestige XC, Attain XC and OcTTain XL, all of which are approved for sale for use only in the Prairie provinces and B.C. Peace River region.

“Aerial application provides another option to minimize weed competition and get crops off to a good start,” Lorne Thoen, product manager for Dow Agro’s Calgary-based Canadian arm, said in a release. “The ability to apply these products by air helps ensure that broadleaf weed populations do not get out of control on growers — regardless of spring conditions.”

Attain XC, which combines fluroxypyr and 2,4-D ester, is thus approved to be ground or aerial applied to durum, spring, winter wheat, barley and forage grasses in the early-four-leaf crop stage for control or suppression of over 40 broadleaf weeds, at a rate that can be adjusted to 40 or 53 acres per case, depending on weed conditions.

Prestige XC, a tank mix of fluroxypyr, clopyralid and MCPA billed as providing “exceptional” control of Canada thistle and sow thistle, has application rate options of 27 or 20 acres per case.

OcTTain XL, also a co-formulation of Group 4 actives fluroxypyr and 2,4-D, is registered for control or suppression on 30 broadleaf weeds and is billed as “particularly well suited for the southern regions of Saskatchewan and Alberta.”
