- Quadris 2F from Syngenta, the first strobilurin (FRAC group 11) fungicide on the market, is coming off patent and a number of companies are expected to apply to manufacture and sell is under another name. Thus, in the 2015 Vegetable Recommendations Guide you will see references to Quadris (FRAC group 11) switched to azoxystrobin (FRAC group 11) much like we did with changing Bravo WeatherStik (M5) to chlorothalonil a few years ago. As more FRAC group 11 fungicides come off patent in the next few years we expect to do the same.
