Several years ago I received an ag related grant to buy a microscope to use for identifying pollen floral sources in my pollen traps and honey. long story short in a normal non-drought season in central Mn we found minimal traces of corn pollen for a period of 2 weeks. this region is rich with pollen and nectar sources from early April to late Sept and we average some nice crops. corn is a fairly common crop here although maybe not as densely planted as southern MN or IA etc.. so while I don't worry much about my bees eating corn pollen here it could be a much different story elsewhere. ****************************************************** * Full guidelines for BEE-L posting are at: * * http://www.honeybeeworld.com/bee-l/guidelines.htm * ******************************************************
