New Proline Gold: two action modes on sclerotinia

Saskatchewan is the heart of pulse crop production, making the province a good home for sclerotinia.

Large tracts of canola interspersed with pulse crops create a perfect environment for disease. In this setting, sclerotinia has plenty of places to hide, and then suddenly invade adjacent fields. Sclerotinia is one of the biggest economic enemies of broadleaf crops in Western Canada.

“As one of canola’s most dangerous diseases, sclerotinia can severely impact a grower’s yield if not properly managed,” said Jamie Mills, with Bayer Crop Science.

On its own, Bayer’s Proline has proven a worthy adversary of sclerotinia in broadleaf crops. The active ingredient is the time-tested Group 3 component prothioconazole. But there are times when outbreaks are so severe that Proline by itself cannot handle the situation.

Now, there’s a new active ingredient farmers can add to the mix.

The addition of Group 7 fluopyram creates a totally new product called Proline Gold. It was developed to give pulse, canola and dry bean growers a higher level of protection against severe sclerotinia infections.

Producers with ongoing disease problems will be the main customers for this multi-mode of action fungicide that offers systemic and contact protection.

One month ago, the Pest Management Regulatory Agency expanded the Proline Gold label to include anthracnose control in lentils, including Group 11 fungicide-resistant biotypes..

This expansion is complementary to Bayer’s pulse fungicide line-up, including Delaro fungicide. This offers growers solutions across crops, disease and resistance concerns. It’s recommended to use Delaro with Groups 3 and 11 in your first pass for broad-spectrum disease control.

If disease concerns warrant a second pass, Proline GOLD with Groups 3 and 7 offers white mould control, as well as control of anthracnose.

Proline GOLD provides protection in high disease pressure situations against sclerotinia. The combination of two powerful actives, Group 3 prothioconazole combined with Group 7 fluopyram, provides protection from sclerotinia. Before the addition of Group 7 fluopyram, Proline was already the top selling fungicide for canola growers.

“In a western Canada, six-year study, Proline delivered an average yield increase of 3.7 bushels per acre over the untreated check,” said Mills.

The suggested retail price of Proline is $867 per jug and Proline GOLD is priced at $927 per jug.
