Sort Questions
Will this work on black knot and if so how would it be applied to the tree?
Junction Fungicide/Bactericide is labeled to control Black Knot on ornamental stone fruit trees such as apricot, almond, cherry, nectarine, peach, and plum trees. You would apply as a thorough coverage spray usine 1.5 - 3.5 lbs of Junction per acre. 0.5 tablespoons of junction per gallon of water is equivalent to 1.75 lbs of Junction per 100 gallons of water. Begin applications at first sign of disease and retreat on a 7-14 day interval as needed. Use shorter intervals when severe disease conditions exist. Maximum seasonal rate per acre is 66.7 lbs of Junction.

Does Junction applied at silverbud on prunus & malus trees poison the trees?

My orchard has various varieties of prunus and malus specie trees affected by bacterial spot, bacterial cankers, peach leaf curl, cedar-apple rust, cedar-quince rust, fire blight and phytophthora and pythium in soil. Will Junction handle all these fungal problems? Furthermore, will fruit from these trees be edible next growing season after these fungal infections have been killed?

Junction is labeled for most of the diseases that you have mentioned, however it is for ornamental plants. You should contact a local Master Gardener or the manufacturer, SePRO for more information regarding timing. We would not recommend eating fruit from trees treating with this product. You can reach SePRO at 800-419-7779.
