As long as the outside temperature is above 45 degrees, you can still treat pines and conifers through November with ArborSystems Shepherd Fungicide. Treatments can be made anytime during the growing season which includes fall. And fall treatments provide a carry over to the following year giving a minimum of 12-month preventative and curative protection. Diplodia Tip Blight is a fungus disease affecting pines. And Shepherd was just approved last year to treat Diplodia Tip Blight by direct injection which lets you place the chemical where the conifers can easily absorb it. So no more spraying avoiding chemical drift into unwanted areas.
