A pair of well-known cereal fungicides has been approved for combined use, allowing cereal growers new dual modes of action against diseases.
The Canadian crop protection arm of chemical giant BASF on Wednesday announced regulatory approval for Twinline, a liquid combination of its crop fungicides Headline and Caramba, for use on wheat, barley, oats, rye and triticale.
"I believe growers are looking for a new level of leaf disease control for cereals, and Twinline delivers," Mike Bakker, BASF’s Canadian brand manager for fungicides, said in a release.
Twinline’s registration from Health Canada’s Pest Management Regulatory Agency (PMRA) covers it for use nationwide, but the product will not yet be rolled out in Ontario until it receives its classification there, the company said.
The company said the new product can be used for control of a "broad range" of leaf diseases in cereals, including tan spot, septoria leaf spot, leaf rust, stripe rust, spot blotch, net blotch, scald, crown rust and powdery mildew, at application rates of 0.38 to 0.5 litres per hectare.
The product is also registered for suppression of fusarium head blight in wheat, barley, rye and triticale at a higher rate of application, 1.14 L/ha.
Results with Twinline in large-scale federal research authorization trials across Western Canada in the past two years were "very positive," BASF said, with "excellent" leaf disease control leading to an average yield response of two to four bushels per acre.
The company has recently been branding Headline’s benefits to protected plants — apart from its direct benefit in controlling crop diseases — with the name "AgCelence," which it said it plans to use in marketing Twinline as well.
"AgCelence gives Twinline crops greener leaves, stronger stems for better harvestability, and higher yield potential," the company said in a statement.
The active ingredients in Twinline include Headline’s Group 11 active, pyraclostrobin, at 130 grams per litre, and Caramba’s Group 3 active, metconazole, at 80 g/L. Twinline’s product label notes it should not be used for more than two applications per season.
