This information is not a substitute for pesticides labels, which can and do change. Always read and follow the label; the label is the law! i

The most commonly used trade name in the southeast is provided. Multiple trade names may exist for the same active ingredient, and the specification of one trade name does not imply endorsement of this product over others. ii The Insecticide Resistance Action Committee (IRAC, http://irac-online.org/) has developed categories for pesticide modes of action (MOAs). Active ingredients in the same category have the same MOA and should be rotated with other MOAs to reduce the potential for resistance development. iii Preharvest Interval: the time between pesticide application and when the crop can be harvested. iv Reentry interval: the time between pesticide applications and when workers can reenter the field without personal protective equipment. v Maximum allowable residue levels for pesticides differ between countries. See the USDA MRL Database (http://www.mrldatabase.com/) for MRLs for countries other than the United States. vi Probably efficacy ratings (E = excellent, VG = very good, G = good, F = fair, P = poor, U = unknown) are based on laboratory and field assays conducted in the western United States as well as our knowledge of the labeled crop. These ratings only apply to active ingredient efficacy against D. suzukii and do not include considerations for beneficial insect impacts or IPM compatibility. vii Endosulfan use will be phased out beginning in 2011 and ending in 2016. All endosulfan uses in blueberries will be terminated in 2016. viii Organically acceptable (OMRI listed).
