Lumbricus is a specific medicine for killing leek maggots. It is a pure biological preparation with no residue, high efficiency and low toxicity. If you wash it once in the leek field, you don't have to take care of it for a quarter, which lasts for a long time. Earthworms not only kill insects, but also promote the growth of leeks. The leek treated with earthworm is obviously better than the leek not treated with this medicine. Earthworms can be used to kill eggs and insects, not only leeks, but also potatoes, loofah, onions, ginger and garlic. The effect is good, and it is not affected by temperature. In order to eliminate underground pests, it is good to look for earthworms with moderate humidity and abundance.
