   Label Expansions for Serenade MAX and ASO Biofungicides for new crops and new diseases

excerpted from J. Chaput, OMAFRA, Provincial Minor Use Coordinator

AgraQuest Inc., UAP Canada and the Pest Management Regulatory Agency recently announced the registration of significant label expansions for Serenade MAX and Serenade ASO Biofungicides for suppression of a number of commonly occurring fungal and bacterial diseases. Serenade MAX and ASO are derived from the bacterium Bacillus subtilis and offer growers an effective biological control alternative for these diseases.

Serenade MAX and ASO are broad spectrum, preventative biofungicides that can be applied as a foliar spray alone, or in an alternating spray program with other registered crop protection products. For maximum effectiveness they should be applied prior to or in the early stages of disease development.  The biological mode of action of Serenade MAX and ASO means that they are suitable for use in a disease resistance management program with other registered fungicides.

The following table provides a summary of the new tomato disease registrations on the Canadian labels for Serenade MAX and ASO Biofungicides.  For detailed instructions consult the full Serenade MAX and ASO labels.

New Crop(s) addition

Disease(s) addition

Rate ASO (L per ha) 

Rate MAX (kg per ha) 

Application Instructions

 

Tomatoes, Peppers 

Bacterial spot

4 - 15

1 - 3

Begin application soon after emergence or transplant and when conditions are conducive to disease development.  Repeat as necessary on a 7 to 10 day interval.  When environmental conditions and plant stage are conducive to rapid disease development, use Serenade MAX in a rotational program with other registered bacteriacides.

Serenade MAX and ASO biofungicides should be used in an integrated disease management program and in rotation with other management strategies.  Follow all other precautions and directions for use on the Serenade MAX and ASO labels.

This minor use project sponsored by the Minor Use office of OMAFRA was submitted in June 2008 in response to minor use priorities identified by producers and extension personnel.   Because of the size of the submissions, PMRA converted the submission to a Category B submission; however we worked very closely with the registrant and PMRA to maintain the review as though the projects were still label expansion submissions.

We also wish to thank the personnel of Agraquest Inc. and UAP Canada Inc. for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
