Sprayed All Roses for BlackSpot


1/14/2020 – Based on the extract below from the label for Propiconazole 14.3.
8 oz / 100 Gallon = 0.08 oz/Gal
0.08 oz = 1/2 tsp or 2.37 ml

[B] Mix 5-8 fl. oz. of Quali-Pro Propiconazole 14.3 in 100 gals. of water and apply as a full coverage spray to the point of drip. Apply as needed, beginning when conditions are favorable for disease development. For blackspot, apply with a registered contact fungicide labeled for black spot. For calendula, apply every 30 days. For diplodia tip blight, make 3 applications every 14 days prior to major period of infection. For juniper phomopsis blight, make first application as soon as junipers start to grow, and repeat the applications every 14-21 days during periods of active growth

Actually mixed 2 tsp of Propiconazole 14.3 in 2 gallons of water with 1 tbsp of Dawn to serve as an on-contact black spot killer. Sprayed all the roses to drip as well as a quick pass underneath the leaves.

“All” roses means:

  • all those in beds around and near the house;
  • the two Julia Child roses in pots;
  • the roses in the Bay Tree Bed that have very few leaves;
  • the lone roses along the fence;
  • the climbing roses at the gate and;
  • the white roses in front of the climbing roses.

The Knock Outs and Julia Child roses are blooming.

As a test sprayed the yellow daylily on the east side of the front porch that always has a lot of rust. I also sprayed the two westside lilies at the historic fence bed of the four on that end.
