In the first method, dissolve 1 tablespoon of ground red or black pepper in a bucket of water and spray the plants before rinsing. The active components of the pepper will help repel carrot flies and protect the plants.

Another method is to use a potassium permanganate solution. After the second thinning, at the beginning or after July 10, water the seedlings with water with boric acid and potassium permanganate. In 10 liters of water dilute 2-3 grams of potassium permanganate and the same amount of boric acid. We water the plants with this solution. After 17 to 20 days, the procedure needs to be repeated.

These methods will help reduce the number and damage caused by carrot flies, ensuring healthy plant development.
