Note: All brands are registered trademarks. The brands listed in this table are not all-inclusive, but are meant to provide examples of products for these crops in Utah. Always check the label for the specific crop you are treating, application and safety information, and protection and pre-harvest intervals.

Protection of Pollinators: Look for the “bee-box” or “bee hazard icon” on product labels and read the restrictions and instructions to protect bees and other insect pollinators. Bees and other pollinators will forage on plants when they flower, shed pollen, or produce nectar. Follow these steps when using products that are hazardous to bees: 1) minimize exposure of the product to bees and pollinators when they are foraging on pollinator attractive plants around the application site 2) Minimize drift of the product on to beehives or to off-site pollinator attractive habitat as drift into these areas will kill bees

Warning: Applications of insecticides in MoA Group 4 are restricted to post-bloom and only when bees are not active in the site, including on weeds and non-crop plants.
