You will want to not mow your yard 2 days prior to application of Clearys 3336 DG Lite Granular Fungicide or 2 days after application to allow it is fully absorbed into the yard and to see the full results.
Clearys 3336 DG Lite Granular Fungicide is really not the best choice for treating Anthracnose in deciduous trees. It is labeled to treat only soil borne diseases in deciduous trees. Instead we would recommend the liquid Clearys 3336F.
Per the product label, you would apply as a foliar spray at a rate of 12-16 fl oz/100 gallon Apply as buds break or at first sign of disease. Repeat at 7-14 day intervals as needed during disease period.
Clearys 3336 DG Lite Granular Fungicide is a Group 1 fungicide.
There is a chart on the last page of the Clearys label that shows different spreaders and the setting to use. If your Scotts spreader is not on this chart, we recommend contacting the manufacturer for help with your specific spreader. You can reach Cleary Chemical at 1-800-524-1662. You can also view a video on how to calibrate your spreader at the bottom of our Granular Spreaders page here.
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.
