Mildew - Cornell fungicide formula
|
| Answer/Pointer: |
The Cornell fungicide formula. This spray will help prevent and/or control blackspot and mildew on roses--as well as powdery mildew on summer squash, early blight on tomatoes and alternaria leaf blight on melons.
Add 1 (one) tablespoon each of baking soda and oil--either a light horticultural oil or regular vegetable oil, add a bit of insecticidal soap (the amount recommended for mixing with a gallon of water). Shake well before and during application.
If weather is humid or threat of disease is high, spray every five to seven days. Spray both sides of leaves thoroughly at the first sign of disease.
(Remember: always test any spray on a small area before spraying your entire plant!)
