Most summer residents use seed bulbs sprouted from seeds as material for planting this fruit and vegetable crop. Gardeners claim that a seed-grown planting is capable of producing more root crops that will perfectly complement a fruitful family table. Carrying out simple agrotechnical measures for the processing of seeds before planting work can positively affect the resistance of a plant to pests and a number of diseases. In addition, additional preparation before sowing has a good effect on the course of the growing season, into which the developing onion seed passes, and the process of root formation.

About the need for processing

A few years ago, almost not a single summer resident wondered what it was necessary to process onions before planting, since this culture has long been considered unpretentious in care. All preparatory measures before planting work were reduced to a bulkhead in order to remove painful and rotten planting material before planting in the garden.

However, today's environmental conditions and climate differences in the regions oblige to carry out agrotechnical measures for pre-planting seed treatment.

The reasons why it is worth carrying out a pre-sowing complex of processing measures are:

  1. Positive effect on growth rate;
  2. The disinfection procedure destroys harmful bacteria;
  3. Resistance to a number of diseases increases;
  4. Reduces the likelihood of root rot;
  5. Resistance to weather changes becomes much higher.

What to process

Thus, the quality indicator of the yield depends not only on how correct care was carried out during the germination of the culture, but also on how competent the pre-plant care was in the form of processing the seed material.

Why process onions

Proper processing of onions before planting is essential to accelerate the growth and development of root crops.

Note. Each small onion head, the diameter of which does not exceed 1 centimeter, can be stored at a temperature slightly above + 10 ° C.

Before starting planting, the pre-sowing planting material must be warmed up at + 35 ° C temperature, depending on the size of the seed:

  • large bulbs - 2 weeks;
  • small onions - 10 days.

The sevok is warmed up in order to reduce the number of darting plants.

If it is not possible to carry out the pre-planting treatment in stages, the bulbs should be placed in boiling water at a temperature of + 50 ° C for 10 minutes, after which the planting material should be lowered into cold water for 10 minutes. Further, the onion set must be kept in a solution with complex mineral fertilizer for 4 hours.

Disinfection of onion sets is needed in order to prevent infection with certain diseases, as well as accelerate plant growth. The most commonly used method, the better to process the onion, is to keep the oatmeal for half an hour in a potassium permanganate solution, made at the rate of 1 gram per liter of water. Also for the same purpose, you can use 3 grams of copper sulfate, dissolved in a liter of water.

Copper sulfate

Most commonly used remedies

You can process the onion before planting with one of the widely used tools:

  • salt;
  • soda;
  • phytosporin;
  • pyrantel;
  • potassium permanganate;
  • boric solution (acid).

Salt seeding

This method consists in the fact that first of all the bulbs are dried at + 24 ° C for a week. After that, it is necessary to prepare a saline solution at the rate of 1 tablespoon per liter of water, where the onion is placed for 3 hours. Next, the sevok should be washed and dried, after which it should be planted. The advantage, which is remarkable for the use of the salt method of processing, is the strength of ripe root crops, immunity to many diseases, and also the fact that the plant has practically no arrow.

Soda processing of planting material

Soaking the onion sets in soda can be carried out both in the spring and autumn seasons. The action of this processing method is aimed at increasing the quantitative indicator of yield, as well as stopping the shooting process.

The high efficiency of this method is due to the antiseptic properties of soda and the high temperature of the solution, which must be at least 50 ° C in order for the drug's effect to be maximized.

Soap solution with soda

To do this, you need to take 1 teaspoon of soda powder, poured with a slide, and 1 liter of water + 50 ° C temperature. After mixing these two ingredients, let sit for half an hour. To keep the water temperature high in the container as long as possible, cover it with a lid and wrap it in a blanket. Before starting to soak the bulbs, the top layer of the husk is removed from them, but you should not get rid of it completely. When planting onions in the fall, pruning is prohibited, due to the increased risk of various diseases.

Treatment with Fitosporin

The purpose of the use of this tool is to prevent fungal infections of root crops. To do this, 35 grams of Fitosporin must be diluted in 10 liters of water, and then placed in the prepared onion solution for 30 minutes.

Pirantel treatment

Watering onion seedlings with a solution based on the Pirantel product is aimed at destroying the larvae of the onion fly. To prepare it, you need to dilute 5 tablets of this drug in 10 liters of water.

Other folk remedies

The list of other folk remedies for processing bulbous planting material for planting work includes the manufacture of formulations based on the following natural ingredients:

  • ammonia;
  • wood ash;
  • laundry soap;
  • tobacco dust;
  • Birch tar;
  • folk infusion of dandelion;
  • infusion of herbs with a strong aroma;
  • metronidazole.

Wood ash

Methods for preparing each of the folk compositions:

  1. The solution, made on the basis of ammonia, is aimed at destroying the larvae that are laid by the onion fly. Ammonia is an ammonia solution, which, in addition to the ability to destroy pest breeding centers, serves as a fertilizer for the garden soil. Despite the absolute safety for onion plantings, you should adhere to the recommended dosage: dissolve 3 tablespoons of ammonia in 10 liters of water, in case of significant damage to the plantings by this pest, and 2 tablespoons per 10 liters of water, when the first signs of deterioration of the plant's condition appear. For a longer time to retain moisture in the soil, watering the onion is necessary in the evening. Avoid using a root irrigation technique by distributing the liquid composition over the entire planting area. To spread the smell of ammonia over a large area of ​​the aisle, loosen it with a garden rake;
  2. The processing of onions with a composition based on wood ash is aimed at destroying the onion fly, as well as enriching the soil composition.Fertilization with this component consists in spreading 2 kilograms of ash over the soil surface over an area of ​​10 m2. However, before carrying out this procedure, you should loosen the ground to a depth of 3 cm. Such treatment, which destroys this type of pest, is carried out once in each season;
  3. The soap solution is used to kill larvae and adults of onion flies. This procedure is carried out 2 times per garden season. To make such a product, you need to finely chop 50 grams of laundry soap, which is then dissolved in 10 liters of water. For a longer retention of the beneficial composition in the soil structure, it is recommended to water the plantings in the evening;
  4. Treating onions with tobacco dust infusion is an old way to get rid of onion flies.

Note. Retail sales of tobacco dust are household stores.

In addition, it is recommended to carry out dry treatment with tobacco dust, distributing this substance over the entire planting area, and then slightly loosen the soil. However, if you want to prepare a tobacco infusion, you need to dissolve 200 grams of tobacco dust in hot water with a volume of 10 liters. Before spraying onions once a week, this composition should be infused for 2 days;

  1. Treatment with dandelion infusion is considered the easiest and safest method for killing onion flies.

Helpful advice. For greater efficiency, it is recommended to alternate the onion treatment with dandelion infusion with salt treatment.

To prepare the solution, you must grind 200 grams of dandelion leaves and roots, then pour 10 liters of hot water, stir and leave to infuse for several days. This composition is used for two-time spraying of plantings in one week. It is recommended to water the onions in the evening so that the garden bed can preserve nutrients as long as possible;

  1. The herbal infusion contains the following components:
  • mint;
  • Melissa;
  • sagebrush;
  • valerian.

Finely chop 200 grams of each type of herb and pour hot water in a volume of 10 liters, then leave for several hours. The safety of this method of processing allows this procedure to be carried out an unlimited number of times - either by spraying or watering;

  1. The use of metronidazole is considered a new method for treating onion sets before planting to prevent onion flies. This tool is sold in pharmacies in the form of tablets. To make a solution, 5 tablets must be crushed to a state of fine crumbs and filled with 10 liters of clean water. The land is watered with such a composition once a season.

Important! The remnants of this substance must be washed off a couple of hours after treatment, after which root watering is carried out.

The processing of seed material, as well as the processing of onion sets in the spring before planting, are necessary agronomic measures carried out before planting a given crop. It is necessary to choose a method of how to process the onion before planting, which is most suitable for a particular site. It is no secret that with careful processing at the end of the season, it will be possible to harvest a good harvest of high quality onion root crops.
