Can a soil drench using Monterey Garden Phos Systemic Fungicide be used to control leaf spot on Photonia?

On the instruction leaflet, spraying is listed as the only method. Pls clarify.


Monterey Garden Phos Systemic Fungicide is labeled for use on ornamentals including photinia for bacterial blights, downy mildew, and phytophthora and pythium species as listed on the product label. These listed diseases can be treated with a foliar spray, soil drench, soil incorporation, or bare rooted dipping of transplants. Leaf spot on red tip photinia is typically caused by Entomosporium, for which we would recommend using Fung-onil Multi-Purpose Fungicide Concentrate. This article has great tips on cultural steps needed to control Entomosporium leaf spot on photinia.
