BRAVO AND ECHO PROPOSED CANCELLATION
Products Bravo and Echo contain the active ingredient chlorothalonil that is now being proposed for cancellation. In tree fruit crops, it is used to control peach leaf curl in peaches and nectarines, and brown rot.- For peach leaf curl, the only other crop protection products are copper products and Syllit (U12).
- For brown rot, chlorothalonil is one of the few Class M (multisite) fungicides available. Without multisite fungicides in a rotation, growers are forced to rely on single site fungicides if they are available, such as Class 3 DMI, Class 7 SDHI and Class 11 QoI fungicides that all pose a greater risk of pathogens developing resistance.
How did the review by the PMRA lead to this proposed cancellation? The special review looked at data concerning chlorothalonil use based on updates to environmental fate and ecological endpoints and human health. The conclusion is that chlorothalonil use poses a concern for human health and the environment according to current use patterns when considered altogether.
Prior to their decision becoming final, stakeholders can submit their comments during the consultation period. Submitted comments will not negate the scientific information that was reviewed but could help to correct assumptions. The hope is that use patterns could be amended to satisfy safety requirements and the need for crop protection. There are two ways to comment:
- The Fruit and Vegetable Growers of Canada (formerly CHC) is asking for grower input on how chlorothalonil is actually used. In the absence of this additional information, PMRA must use the most conservative scenarios during their risk assessment process (e.g., 100% crop treated, maximum possible application rates, etc.). Responses to the survey, which is anonymous, are requested by no later than April 15, 2022. Fill out the survey here: https://www.surveymonkey.com/r/NJ3WJHF
- Provide your comments directly to the PMRA Publication Section by May 11, 2022.
