I forgot to mark the boundaries of where I intended to plant some trees, and sprayed the weeds in those areas. I see this note on the label "Do not plant any crop other than turfgrass species for 18 months after the last application of Tenacity or injury may occur." Is injury referring to harm to a person digging a hole and handling the soil or injury if a food crop is planted there and someone later eats that crop. So basically, is it safe for me and for the tree, to dig a hole and plant a tree in an area sprayed with Tenacity?
Per the manufacturer, the 18 month waiting period after an application of Tenacity Herbicide applies to food crops but there are some trees that can be sensitive as well. Digging a hole where Tenacity was applied should not have much active ingredient residue, especially if the sod/grass is removed to plant the tree. Waiting 3-6 months after application would be acceptable.
