A high yield of vegetables, first of all, depends on how well and correctly the seeds are prepared for sowing in the ground.

There are many ways to prepare seeds, but there are some that simply cannot be ignored if you want to achieve good results.

At the same time, in no case should the seeds be subjected to all these operations, because even the strongest seeds will die. You only need to do the most necessary for your seeds, for your greenhouse.

Moreover, for different growing conditions of seedlings, the required set of these pre-sowing procedures can be completely different.

Let's talk about disinfection (dressing) of already calibrated seeds.

Disinfection of seeds

In recent years, much has been said about the need for pre-sowing seed treatment. It is almost impossible to distinguish diseased seeds from healthy seeds in the usual way. And it is with them that many formidable diseases of vegetable crops are most often transmitted.

Therefore, in order to protect seed germination from fungal and bacterial diseases, it is first of all necessary to carry out seed dressing, which will destroy pathogens on the surface and inside the seeds and protect them from pests and diseases in the soil. After all, there is no guarantee that clean and healthy-looking seeds do not carry pathogens.

With the seeds of cucumber, for example, infections of anthracnose and angular spot are transmitted, in beets - peronosporosis and phomosis, in cabbage - vascular bacteriosis, peronosporosis and phomosis, in carrots - black rot, and so on.

That is why dressing and heat treatment of seeds, especially those purchased from a street tray or on the market, is a strictly mandatory method of preparing seeds for sowing.

Seeds are not disinfected only in two cases: if the packet indicates that disinfection has already been carried out and if the seeds are pelleted.

Vegetable seeds are disinfected using various dry and wet methods. Among the dry methods, the simplest and oldest is keeping the seeds in the open sun on the veranda for 5-7 days. At this time, the seeds must be mixed on a platter several times a day.

This method is especially reliable for the seeds of heat-loving crops such as cucumber, pumpkin, squash, beetroot, especially if they have been kept in a cold room for a long time. The sun's rays not only disinfect seeds from microorganisms, but also actively stimulate their germination.

The use of special preparations in a dry state for disinfection of seeds also looks very simple from the outside. Such disinfection allows, when shaking, for example, seeds in a bag with a fungicide, to create a uniform (thin layer) coating. However, it is better to refuse such a procedure in the conditions of an apartment, because the danger to health is too great, since it is impossible to guarantee complete safety when using these drugs.

For wet disinfection of seeds, many gardeners still, like our grandfathers, use a 1% solution of potassium permanganate, although some experts are rather skeptical about this method.

But not every gardener knows how to properly prepare a solution of potassium permanganate of the required concentration. Indeed, the overwhelming majority of gardeners do not have the opportunity to weigh 1 g of potassium permanganate at home, and therefore puts it by eye. Without weighing, you can quite accurately determine the required amount of potassium permanganate using … a standard teaspoon (5 ml). Such a teaspoon without top contains 6 grams of potassium permanganate. "No top" means that excess potassium permanganate must be removed from the spoon with the flat side of the knife.

The modes of seed treatment with potassium permanganate are as follows:

Seeds of tomatoes, onions, celery, lettuce, radish, beans, peas, beans should be processed in a 1% (dark pink) solution of potassium permanganate at room temperature for 30-40 minutes, followed by rinsing in water.

And the seeds of eggplant, pepper, cabbage, carrots, pumpkin crops, dill are best disinfected in a 1.5% (dark purple) solution of potassium permanganate for 20 minutes, followed by washing the seeds with water.

2-3% may be used for seed treatment -th solution of hydrogen peroxide preheated to 38-40 of the C, wherein the seed is held for 7-8 minutes.

Many gardeners pickle tomato seeds in a solution of boric acid (0.2 g per 1 l of water) or copper sulfate (0.1 g per 1 l of water). This treatment also fully protects tomatoes from disease.

Care should be taken that there are no stuck together seeds, for example tomato seeds stick together, because however, you may not get the desired result.

For bacterial diseases, many gardeners often treat vegetable seeds with aloe juice. To do this, the leaves of indoor plants are kept for 6-7 days in the dark at a temperature of + 2 ° C (in the refrigerator door), then squeeze the juice and dilute with water in equal shares. The seeds are kept in the resulting solution for 18-24 hours.

Against vascular bacteriosis, the seeds of cabbage and its "relatives" are often treated with garlic infusion. To do this, 25 g of highly crushed garlic is mixed in a jar with 100 g of water, the seeds are kept in it for 1 hour, and then washed and dried.

You can disinfect seeds in a mustard solution. To do this, pour 1 teaspoon of dry mustard with half a glass of warm water, stir well and place the seeds in this suspension for 2-3 hours, stirring it occasionally. Then the seeds must be washed with cold water and dried.

A water infusion of wood ash is also useful, which contains almost 30 nutrients. To do this, the seeds are placed in a daily infusion of ash (half a glass of ash per 1 liter of water) for 4-6 hours.

In recent years, most often the seeds are kept in a weak solution of biological products Rizoplan, Trichodermin, according to the instructions attached to the drug. And immunocytophyte helps well against viral diseases.

And supporters of the organic live farming system (OZH) recommend using the drug "Fitosporin-M" to protect against diseases. Before sowing, to protect against diseases, the seeds must be processed in it according to the instructions, preferably together with the "Gumi" preparation to stimulate growth and development.
