moss control in strawberry bed
Personally, I would not use this product near any edibles (whether or not it is bearing any fruit yet). Here's a link to the warning label for Moss Out. I would leave it to your own judgement to take the risk: https://www3.epa.gov/pesticides/chem_search/ppls/000802-00509-20110818.pdf
I would investigate more organic methods to rid your lawn of moss, or move your strawberries to an area that will not be cross contaminated with any synthetic moss-removal agent.
