Imagine the situation: you planted a young strong seedlings of cabbage, and literally the next morning you found that the leaves of seedlings turned into a continuous sieve. Blame it all - a microscopic black flea. Let's first understand what kind of insect it is and where the fleas on the cabbage come from. So, first things first.
Black fleas on cabbage (or, as they are also called,
cruciferous fleas) belong to the genus of phyllotret. These insects are very small (no more than 3 mm in length), they jump very well, can be not only black, but also green and blue. This type of pest is dangerous for young plants and still fragile seedlings: with numerous invasion of fleas, young plants can be completely destroyed.
Despite the small size of the pests, they are quite simple to notice: when you touch the leaf of seedlings, they will begin to jump from the plant in different directions.
Harmful insects eat small holes in the leaves, with very severe damage, the leaves of the seedlings begin to dry out and die.
How to deal with such pests than to process cabbage from a flea in order to save a future crop?
For large areas affected by insects, chemicals containing pesticides are usually used. True, this method does not affect plants very well.
Flea on cabbage is especially active in hot, dry weather. The first insects crawl out of the ground with the advent of spring vegetation, which they feed on. These are usually weeds.
To prevent the occurrence of pests, it is recommended to carefully weed the places for planting future seedlings. If annoying fleas still attacked young plants, they will have to fight with insects.
What to process? Cabbage from a flea can be sprayed with a solution of ash, garlic or tobacco. It is advisable to carry out such a procedure in the morning. In addition, insects do not like the presence in the vicinity of cabbage of crops such as tomatoes, onions, garlic.
Gardeners recommend using old folk methods of pest control. How to process cabbage? Watering young plants with very cold water early in the morning will save them from fleas, and this should be done for several days.
Another important point. Throughout the summer, you must carefully monitor the appearance of insects. The fact is that during the warm season, fleas can give up to three offspring, so when re-sowing
radishes, radishes (these vegetables are also goodies for fleas), seedlings must be carefully monitored. At the slightest threat, you should use proven methods.
Of course, when fighting harmful insects, you will have to work hard by watering and spraying the plants. Of course, you can kill insects at one time, however, for this you will have to use special preparations such as, for example, Iskra (1 tablet is diluted in 10 liters of water).
Only you will have to decide on how to process cabbage from a flea. Whether it will be special chemicals or organic methods - it does not matter. The most important thing is to pay attention to insects that have appeared in time, so that you can begin to destroy them as soon as possible before the pests have time to "eat under the root" your future crop.
