One of the methods involves planting mustard next to potato beds. Its strong scent effectively repels Colorado potato beetles, causing pests to avoid the area, while the tubers remain unharmed.
Additionally, gardeners recommend a homemade solution made from mustard powder for treating plants. The preparation involves mixing mustard powder with hot water, vinegar, and grated household soap. This solution helps create a protective barrier on the potato leaves, deterring pests.
Ingredients:
10 liters of hot water.
200 grams of mustard powder.
5 tablespoons of 9% vinegar.
50 grams of grated household soap (to help the solution adhere better to the leaves).
Preparation of the solution and application:
Dissolve the mustard powder in hot water and let it steep for three hours.
Add vinegar and grated household soap to the mixture and stir thoroughly.
Use the solution to treat the potato bushes, ensuring the leaves are thoroughly covered.
This mustard-based treatment is a natural and effective way to protect potatoes from pests without the use of harsh chemicals.
