Disinfection of seeds: three reasons why you should not skip it, so as not to be left without a crop


Disinfection of seeds before planting is an important procedure that should not be neglected. But among the many methods of preliminary processing of planting material, you need to choose the right one. Excessive exposure can result in the plant not even germinating.

Increased germination energy

Regardless of the quality of the planting material, many gardeners are faced with the problem of non-germination of a large number of seeds. The reason for this may not be the manufacturers at all, but the insufficient amount of nutrients in the soil. It is for this reason that specialized solutions have been developed to accelerate seed germination.

In the process of processing, the planting material is saturated with the necessary microelements and growth stimulants. In addition to the main function, disinfection allows you to increase the immunity of future seedlings and improve their resistance to unfavorable external factors.

Protection of seedlings from insect pests

Even well-sprouted seeds do not guarantee a rich harvest. Young shoots are threatened by numerous insects that live in any soil and are a normal component of its microflora.

Pretreating the planting material from insects and pests will help protect seedlings and allow them to grow to mature fruiting plants. Soaking solutions before planting guarantee 100% protection against nematodes, wireworms, aphids and other insects that can wipe out an entire plantation.

Minimizing and Getting Rid of Infections

Viral, fungal and bacterial infections are another cause of plant death. Of particular danger are crops that cannot be transferred in the form of seedlings, but are immediately planted in open ground. In the process of germination, seeds in the ground are saturated with moisture and swell, it is during this period that they are most susceptible to attacks by molds, viruses and bacteria. Preliminary disinfection will help to show resistance to various microorganisms, significantly increasing immunity and guaranteeing the growth of healthy plants.

1. For disinfection of instruments.

When working with soil, vegetation, it is important that the tools are clean. Before pruning the garden, the pruning shears and saw blades are wiped twice with an interval of 3-5 minutes. It is advisable to process the sharp part of the hoe, shovel and other tools at least 2 times a season - in autumn and spring.

2. For disinfection of the sections during garden pruning.

After removing diseased and excess branches, the cut site must be moistened with a cotton swab abundantly moistened with chlorhexidine.

3. For soaking the planting material.

Before germination, seeds must be pickled in order to destroy harmful microorganisms. For these purposes, potassium permanganate, hot water, copper sulfate are used, but this can also be done with chlorhexidine.

The drug not only disinfects the seeds, but also has a stimulating effect, thanks to which the seeds germinate faster, the seedlings will grow strong and healthy. It is enough just to dilute the preparation with water in proportions 1 to 1, hold the planting material in it for about a day.

4. For soil disinfection before planting seedlings.

When growing seedlings, it is important that there are no fungi and bacteria in the ground that cause various diseases. If you just take the soil from the garden, do not process it with anything, then the likelihood that the plants will survive is small. It is necessary to spill the soil collected in the container 2 weeks before planting the seeds with a mixture of water and an antiseptic. For 2 liters of water, 50 ml of the product is required.

5. For disinfection of containers before planting seedlings and indoor plants.

When planning to transplant flowers, grow seedlings, you need to take care that harmful fungi and bacteria do not remain on the containers. First, the container is washed with soapy water, dried, and then wiped with a cloth moistened with the drug.

6. For preventive treatment of plantings.

Considering that at any time the plants in the garden can be struck by diseases, it is worth preventing trouble by sprinkling the green mass from a spray bottle weekly with a mixture of 3 liters of water and 30 ml of chlorhexidine. Large sheets can be wiped clean with a cloth dampened in the solution.

Chlorhexidine is an effective and inexpensive agent that helps prevent fungal and bacterial diseases.


Why is it important to disinfect

The greenhouse becomes a haven for many pests and all kinds of pathogens, because they love moisture.

Also, dust, debris, plant residues accumulate in the corners of the greenhouse and other secluded places, and they can become a breeding ground for weed seeds, spores and bacteria.

The lack of disinfection of the greenhouse leads to only one thing - you can ruin the crop. Therefore, it is worth learning about the basic recommendations and effective preparations that will help get rid of most pests.


Seedlings stretched out under a hood (foil, lid)

This also applies to insufficient lighting. Once the seedlings have formed the cotyledons, the cap can be removed. Do not overgrow the seedlings under cover and do not forget to remove it daily and ventilate the crops.

The film was removed from the basil seedlings too late

Be sure to remove the caps and films from the seedling trays within a few days of germination. Seedlings left to grow in these conditions develop thin stems like threads, too fragile to survive in excessively humid or hot conditions.


Indoor plants, like outdoor plants, are susceptible to diseases and pests. Most often this is due to improper care on them.

Excessive or insufficient watering, excess fertilization, dry air - all this can cause diseases.

The best way to fight - this is, of course, prevention. Check plants for disease by looking at leaves. Quarantine recently purchased or donated flowers until it is known for sure that it is not sick.

If the disease was discovered, you need to understand in what ways you can get rid of it.

When pests attack flowers, it is necessary to use special preparations - insecticides... These chemicals kill insects, their larvae and eggs.

According to the spectrum of action, insecticides are divided into preparations of continuous and selective action. Insecticides of continuous action fight all insects and pests, selective - with a specific pest.

By the nature of the action, insecticides are divided depending on the action exerted on the pest:

  • contact - affect the pest at the first contact
  • intestinal - when a pest enters the body, it causes its poisoning
  • systemic - kill all pests on the surface of the plant, inside its root system, leaves and trunk. The poison moves through the plant itself and poisons everyone who feeds on it.

The most popular drugs are: Fitoverm, Gaupsin, Aktellik, Biotlin.

For diseases and fungi, drugs called fungicides help.

They are divided into systemic, which penetrate into plant tissues and fight the disease from the inside, and contact, located on the surface of the plant and killing the disease upon contact with them.

Fungicides can be used for dressing the soil, dressing the roots or seeds of plants, and spraying them above the ground.

Remember the main thing - when using fungicides and insecticides, you should carefully consider the conditions of their use! Be sure to wear respiratory, eye and skin protection.
