Diseases of tomato seedlings

Tomato is a very popular crop; almost all gardeners grow it. In our country (at least in most of it) this is only possible with the help of seedlings. They begin to grow it in March, lovingly watering and feeding future tomato bushes. Unfortunately, sometimes there are diseases of tomato seedlings, from which she may die, and then the work that lasted for several months will go down the drain, and you will have to buy seedlings for planting. I would compare buying seedlings to buying a pig in a poke; you never know what will grow from it.

The most unpleasant and dangerous disease of seedlings is blackleg. The source of infection is contaminated soil. As soon as it becomes waterlogged or the temperature rises, the black leg becomes active. You can reduce the risk of disease by adding wood ash to the soil. Make sure that the soil does not become waterlogged or overheat; after each watering, add a little dry sand to the soil. This disease affects not only tomato seedlings, but also any seedlings that you grow at home or in a greenhouse.

Diseases of tomato seedlings also include such an unpleasant thing as brown leaf spot. It is a consequence of increased air humidity (this is especially common if seedlings grow in a greenhouse). First, yellowish spots appear on the surface of the lower leaves, and an olive coating appears on the underside of the leaf in this place. Then the spots turn brown and spread over the entire leaf, and the bottom becomes dark brown.Soon these leaves die off. Diseased leaves and completely diseased plants should be destroyed. It is necessary to take measures to reduce air humidity, for example, frequently ventilate the room.
