Recognize and Treat Black Rot


Give Black Rot the Boot.


 

Shriveled berries are not a good sign if you are growing grapes. Neither are dark spotty circles on your grape leaves. These are two indicators that your grape vines may be suffering from black rot, which is a common fungal disease for plants that grow in hot, humid weather. Other plants that have been affected by black rot include apple and pear trees as well as cabbage, broccoli, sweet potato, cauliflower, kale, turnip, and brussel sprouts.

 

If you discover mummified fruit or shriveled veggies in addition to darkly colored lesions on the leaves of your plants, grab your pruning equipment and PreGro Plant Sprayer. This lightweight garden sprayer enables you to deliver a continuous and uniform spray to thoroughly suppress the spores that are infecting your vegetation.

 

Before using the PreGro Plant Sprayer, remove all the ruined fruit or vegetables as well as any spotted leaves. Mix up a cost-effective home-made fungicide and pour into the easy-to-fill glass container. Use the easy-to-control PreGro Plant Sprayer to drench the shoots, leaves, stems, tendrils, and the fruit or vegetables. For grape vines specifically, spray the vines when the new shoots are 2 inches to 4 inches long, when they are 10 inches to 15 inches long, right before bloom, right after bloom, and when the grapes have set.

You Will Need:

DIY Recipe to Combat Black Rot

 

Directions

Using a half-gallon or gallon-sized pitcher, combine ½ cup organic low-fat milk with 1 quart of warm water. Add 3 drops of non-bleach liquid dish soap to the mixture and give it a quick stir before pouring into the PreGro Plant Sprayer glass container. Never shake the PreGro Plant Sprayer when the glass container is attached to the sprayer. The PreGro Plant Sprayer utilizes aerosol technology, but does not contain CFCs. For optimal spray, hold sprayer between a 90 degree angle and a 45 degree angle. Heavily douse the entire plant with this solution. Spray the affected areas every week until you see the black rot diminish, but stop spraying when the fruit or vegetables begin to ripen to avoid leaving a milk residue on the surface.

 

Important Tips:

  • Spray your milk-based fungicide on both affected and healthy plants to ensure fungus spores do not spread.
  • Test your homemade solution on a single plant to make sure the solution is not too strong and will not have adverse effects.
  • Spray this natural solution on your affected plants in the early morning or evening so a hot or sunny day will not cause the solution to heat up and burn the plant material.
