Can the Fertilome F-STop be used as a systemic for trees with leaf spot?
Will tress take up the chemical and act as a systemic fungicide in lieu of spraying?
Fertilome F-Spot is a systemic fungicide, but it is a granular formulation and is only labeled for use on lawns. Eagle 20EW is a systemic fungicide with the same active ingredient that is labeled for leaf spot on ornamental plants and trees. Refer to the product label for more specific listings of tested tolerable plants. You may also want to contact your local co-operative extension office for recommendations on what active ingredients work most effectively on the specific plants you are treating in your area.
