Twisting of leaves in tomato: the main reasons

Many vegetable growers are faced with such problems as twisting of leaves in tomato. It seems that only proven seeds are bought, care of seedlings is carried out with observance of all rules ... But only the hot summer comes, and then problems with seemingly healthy plants begin. Still, for no apparent reason, tomatoes can not get sick, so you should understand and identify the reasons for the sudden deterioration of their appearance. Moreover, the future harvest depends on this.

The causes of the twisting of leaves in tomatoes can be covered in unbalanced top dressings. Ogorodniki fertilize seedlings with nitrogen and organic fertilizers, while forgetting about phosphorus, potassium and zinc. When phosphorous starvation in the plant tip becomes grayish color, violet-red veins appear. With a lack of potassium, the leaves twist upward, the growth point dies off, the fruits, not ripening, are covered with apical rot. The bush becomes small, on it necrosis develops quickly. Leaves pale, and then brown. An excess of zinc is easy to learn by rolling down old shoots. Twisting the leaves of tomato can also talk about the deficiency of sulfur, copper and boron.

Combating this phenomenon is possible only by introducing complex, well-balanced fertilizers, for example, "Rastvorina" or "Potassium monophosphate". It is not necessary to introduce a large amount of slurry or insufficiently rotten manure into the ground, since an overabundance of ammonia often provokes damage to the fruit and burns the leaves. Strangely enough, but excessive watering can also damage the tomatoes. To monitor the moisture of the soil, of course, necessary, most importantly - do not overdo it.

Anomalous heat also causes twisting of leaves in tomato, it does not matter where the seedlings grow - in a greenhouse or in the open ground. In May and June it happens that the land has not warmed up yet, it is quite hot during the day, but it gets colder at night. Such temperature changes adversely affect plants, because the accumulation of nutrients is significantly slowed down, but their decay accelerates. In this case, it is necessary to ventilate the premises of the greenhouse, create drafts, pritenyat seedlings, closing it from the scorching sun.

If the twisting of the leaves in tomato is a consequence of high temperature, then to reduce stress, you can spray bushes with urea (for 1.5 liters of water, add 1.5 tablespoons of fertilizer). In a couple of days, it is worth treating the tomatoes with potassium permanganate - after that the tops will be straightened. If all the rules for growing vegetable crops are observed, and twisting is still observed, then the reason is likely to be the bacterial infection that infected the seeds. It is impossible to cure it, but everyone can stop the spread of the disease. To do this, use the drug "Avixil" or something similar.

Various pests also often attack tomatoes. Seedlings (twisting of leaves can be observed in young plants) can suffer from aphids or other insects. The problem itself is not resolved, so you should immediately buy a special drug to control pests and spray bushes. The choice can be stopped on "Fufanon", "Biotlin", "Alatare", etc.
