I have evergreen trees and I was told I need a systemic disease control product and dormant oil. For systemic disease, I would like to know how to apply Clearys 3336 DG Lite Granular Fungicide to them or if you have a liquid version for that application? Also how much I need for 4 small trees - tallest 7' - only certain spots effected. Also, any suggestion for a dormant oil to buy and its application? Thanks!
Clearys 3336 DG granules are only labeled for use in commercial horticultural applications for evergreens. There is a liquid formulation called Clearys 3336F which is labeled for evergreens. One quart should easily treat your small trees, but how much you apply will depend on what disease you are treating. Per the product label: "For soil drench applications,best crop protection is achieved with preventative treatments repeated every 21-28 days.For foliar applications, begin treatments when disease first appears, or during suspected periods of disease incidence. Apply additional applications every 7-14 days or as otherwise instructed for the prevention or control of the listed diseases." We do sell Hi-Yield Dormant Spray Oil in several sizes as well.
