Twisted leaves on tomatoes - a signal of danger! we solve the problem

If you notice that tomatoes are twisted leaves, you need to take urgent measures to save the plant and the next harvest. This article - the causes of ill-health planting and recommendations on how to rectify the situation with minimal disruption to our tomato plantations.

The leaves of tomatoes are transformed into "boats"

How does it look - look at a photo:

There are 2 reasons why this happens:

1. On tomatoes settled potato aphid (And potatoes, and tomatoes belong to the same genus of plants - nightshade, and they have common pests). It is small and nasty pest. But to get rid of the problem simply by modern insecticides: for example, "konfidor" or "Spark". Always use personal protective equipment, follow the instructions and observe the prescribed dosage. Practice shows that the potato aphid disappears after one treatment. The "severe cases", when the parasite colony reached an impressive size, need a second procedure. Affected leaves are not straight, but new ones will grow straight - what should be.

2. Bad weather conditions. The leaves are curled due to extreme heat (35 ° C or higher). Although tomatoes - highly thermophilic person, rapid evaporation of moisture at high temperature causes the sheet edge to be bent upward. All that you can do in this situation - to provide sufficient irrigation, soil zamulchirovat (so that the water evaporates slowly) and rely on the fact that the heat is coming soon :)

And now for the other kind of twisting ...

Tomato leaves are folded down

But this is a more serious situation. A bacterial disease, a devastating disease for tomatoes - make plant leaves to curl downward. In order not to confuse it with the mineral starvation (About it - below), It is helpful to know the characteristics:

• lower leaves not only twisted but turn brown and then wither;
• to cut the stem (to set the exact diagnosis is worth checking out one of the plant) will see the brown "ring".

A bacterial disease of this type can not be cured and is infectious. We'll have to remove all the infected disease plants. But I can reassure you, there is such a defeat is not often. And fortunately! But the lack of trace elements - a common cause, for whom tomato leaf curl.

Tomatoes do not have enough of micro- and macronutrients

The epigraph to the story of this reason, I would have written the phrase: "Over all not follow". Even with proper and attentive care is not always possible to meet the rapidly growing planting the entire set of required chemicals. Moreover, to establish exactly what is missing in the home is not possible - it is necessary to make complex laboratory tests.

But the need for some substances is manifested most clearly:

• if the tomato needs calcium, the leaves are folded up, and growth points begin to slowly die. Often accompanied by deficiency of the substance apical rot.
• with potassium shortage leaves wither on the edges. According to my observations, the most effective remedy against adversity - potassium nitrate. She is also improves the taste of the fruit!
