Effect of Crab Grass Preventer on Bees
Radio programs on gardening are recommending that Dimension be applied as a crab grass preventer. Before taking this advice, I want to find out if this chemical is dangerous to bees. I'm concerned about the health of our pollinators. Thanks.
Yours is a very good question. We have not seen any research on this. You should contact the National Pesticide Information Center as they are the experts in pesticide safety. They answer questions by email or they have an 800 number for you to call. The following is their website, http://npic.orst.edu/
