Treating Photinia for Entomosporium m.
Hi, Do you have any information on using a diluted cow's milk spray to manage entomosporium on Photinia hedges? We have been successfully using it as a foliage fertilizer and to treat roses for black spot, powdery mildew and for some sucking insects on commercial properties for the past year and are hoping to do the same for some very sadly afflicted photinias. I believe the fungi are different...? Thanks! Sue Thompson
