Black leg disease is the most importantscourge seedlings. It rarely happens that the seedlings grown at home do not suffer from pests and diseases. Usually, we bring all these problems ourselves together with the soil or we provoke them using boxes in which vegetables were stored all winter, and then we are too lazy to steam and sanitize everything. Therefore, there is a black leg in seedlings, which we grow in these boxes.
The disease is favored primarily coldsoil and overflowing. In order to prevent cooling of the soil during the cultivation of seedlings need to put insulation on the windowsills. Also try to observe the cup size, if the seedling is small, then in large cups the earth turns sour. If a seedling seedling disease has appeared, then the first step is to reduce watering almost to the point where the soil is dry. As a rule, then the seedlings stop falling. It is possible to pour calcined sand against the stems, since the formation of a black leg occurs precisely at the interface between the soil and air, and the layer of calcined sand will always be dry. After drying the seedlings, so that the black leg passes at the seedlings of tomatoes, it is recommended that they be watered with special preparations or with a solution of ordinary potassium permanganate.
As prevention of this diseasethe most frequently used are whey, trichopol (one tablet per liter of water) and foundation, preparations of copper, decoctions of herbs. If the leaves of the seedlings of tomatoes appeared blue-red in color, this indicates that the roots are cold and as a result, the supply of phosphorus to the plant becomes insufficient. With a lack of nitrogen nutrition, the leaves become pale, and with potassium starvation, a dry border appears on the leaves.
Of the pests most often plague plantssprout fly, which is also found on indoor flowers. She, too, is the reason that there is a black leg in seedlings. Usually we ourselves often bring it into the house with humus. Also breeding flies contributes to overwhelming. In severe cases, entire hordes of flies sit on the ceiling of the apartment. And at this time, the larvae, representing their numerous offspring, feed on the roots of the affected plants. You can simply collect the flies from the ceiling with a vacuum cleaner, but with the larvae it is much more difficult. They live in the top layer of soil at a depth of five millimeters; after removing them from the pots, this layer must be replaced with fresh soil. But this is easy to do in pots with indoor flowers, and dealing with seedlings will be more difficult.
To get rid of the larvae and passed black footin seedlings, drying the surface layer of the soil helps. The smell of soured berries and vegetables attracts adult flies, so for them you can arrange the appropriate trap. If, nevertheless, all the measures used do not help, then, as an extreme measure, watering the soil with special chemicals is used. The second most common seedling pest is the aphid, which most often appears on peppers. In order to protect against it, it is necessary to always observe its lower leaflets in the seedlings. Aphids should be defeated before planting seedlings in a permanent place. If you bring it into the soil when picking up seedlings in a greenhouse or in open ground, the struggle will be unequal.
All diseases of seedlings and seedlings of tomatoes,Eggplants and peppers, especially when a black leg appears in seedlings, are much easier to prevent than to cure. Therefore, simple preventive methods, which are quite simple to perform, will help protect seedlings from this common disease. Inspect the plants carefully and regularly so as not to miss the onset of the disease and provide first aid to the plants in time.
