What slugs look like
This is a gastropod mollusk, which has a slippery elongated body with a length of not more than 5 centimeters. The color is almost black, so when possible slugs are clearly visible on the green foliage. The main feature is the nocturnal lifestyle that they lead, hunting only at dusk or at night.
The pest eats cabbage leaves. In addition to cabbage, he often switches to neighboring crops. Tomatoes, zucchini, peppers, and eggplant suffer from his attack. The mollusk lives in a dark place where there is high humidity. An ideal place to place slugs is a rotting log, a rusty bucket, wet firewood.
The main signs that slugs attack cabbage are:
- the appearance of large holes on the cabbage foliage;
- the appearance of silver mucus;
- the vegetable begins to languish and grows poorly.
If there is a presence of all these factors, then they immediately begin to save the crop, otherwise the slugs will eat it completely without the possibility of recovery.
What harm does
In addition to the fact that the cabbage loses its appearance due to gnawing holes, it also becomes infected with many infections. Slugs are carriers of almost all known infections. They infect vegetables with rot, powdery mildew, late blight and other equally serious diseases.
A vegetable after slugs is not suitable for consumption, as it can be poisoned.
Reasons for the appearance
Most often, slugs switch to cabbage from a neighboring plant or from a neighboring site. High humidity and low temperature provoke the appearance of pests. If the weather is cloudy and the temperature is 20-22 degrees, these conditions are ideal for slugs.
Sometimes gardeners themselves provoke an attack by mollusks because they do not cultivate the greenhouse in spring and autumn, and they do not dig up the soil and do not water it with insecticides. Neglecting the cultivation of crops leads to sad consequences.
How to get rid
In getting rid of slugs, folk methods of struggle will help. Their action is based on the appearance of a pungent odor or a bitter taste, which slugs categorically cannot stand. It takes 2-3 treatments so that the pests leave the vegetables and do not appear on them anymore.

- 10 liters of water.
The resulting mixture is poured into a spray bottle and irrigated with cabbage, focusing on the lower part and under the leaves. You can water with diluted vinegar and the soil around the cabbage. The treatment is repeated after 3-4 days.
Ammonia
Another substance with a specific odor is ammonia.The ammonia contained in the composition has a beneficial effect on the development of green mass in the head of cabbage, and after processing the cabbage will become lush.
For processing, dissolve 4 tbsp. alcohol in a bucket of water and spray the solution onto cabbage heads. Interval of use is 1 time in 5-7 days. It is enough to use ammonia 2-3 times, and the pests will disappear forever.

Cook the mixture on fire for 20-30 minutes, and then insist another 24 hours. Filter the solution from the husk and spray cabbage 1 time per week 3-4 times a month.
