We hope that everyone has purchased the current version of the Commercial Vegetable Recommendation Guide for 2013 (CVRG-2013). The CVRG-2013 includes new information on insecticides, herbicides and cultivars. The following is a brief overview of some of the changes and updates to fungicides that are included in CVRG-2013. Some of these additions represent newly registered products. Other fungicides were added because reevaluation of trial data indicated that they were effective. This summary is not comprehensive. Also, many of these products have not been tested in replicated trials, therefore comparisons of efficacy with existing labeled fungicides is difficult. Remember to follow all label safety guidelines, rates, resistance management guidelines, and tank mix incompatibilities.
