Olga, 42.

The first time I was frightened by the meeting with the worms that settled on the roots of cabbage. The pest ate not only the roots, but also the stem. The plant began to wither, darken and had to be dug up. Each white worm on the root is no more than 1 cm. I had to remove all vegetables similar to this one at once. The remaining plants were sprinkled with ash and loosened the ground. Now I do a similar procedure when planting crops. I advise everyone, save the harvest!

Ivan, 54 years old

I cover cabbage beds with wormwood, pour pepper or tobacco. The pest does not fly up to the cabbage bush protected in this way. I immediately sprinkle the eaten foliage with wood ash or water the soil with an infusion of onion peel. All these methods help at all stages of plant growth.

Thus, the root system is nourished and protected from insects. In the event of a massive invasion of insects, such proven means as Aktara, Fitoverm are good.
