Tank mix OK for Alta. beans, this year

Dry bean growers in Alberta will be able to use a tank mix of BASF’s herbicides Solo and Basagran Forte to control broadleaf weeds and grasses, under an emergency use registration.

Health Canada’s Pest Management Regulatory Agency (PMRA) has granted emergency use on a request from the Alberta Pulse Growers Association and the Prairie Pesticide Minor Use Consortium, BASF Canada said in a release Thursday.

The tank-mix registration is for use on great northern, pinto and small red dry bean varieties in Alberta only, BASF said.

In keeping with Basargran Forte’s label recommendations, a two-litre-per-hectare nitrogen source, such as 28 per cent UAN, should also be included in the tank mix, the company said.

BASF brand manager Chris Vander Kant said in the company’s release that the tank mix will provide post-emergent control of “problematic” broad leaf and grassy weeds, including Group 1-resistant grasses.

Basagran Forte is a Group 6 contact herbicide for control of broadleaf weeds including ragweed, lamb’s-quarters, velvetleaf, Canada thistle and yellow nutsedge. Solo, a Group 2 product, is used on grassy weeds and “targeted” broadleaf weeds.

PMRA can grant such emergency use registrations for periods “not exceeding one year” in cases where a weed outbreak can cause “significant” economic or environmental problems; no effective product or application method is registered in Canada for control; and there’s no effective alternative control available.

Emergency uses aren’t granted on products or uses with unacceptable health or environmental risks, nor if the active ingredients aren’t registered in Canada. PMRA says it considers such applications only for products that are effective and the risks deemed acceptable.
