Potassium permanganate for the garden: rules for use, how to make a solution and processing time

The use of potassium permanganate for the garden helps to achieve a combined effect. This substance can act as a medicine, top dressing and antiseptic. However, the use of the composition is required taking into account the goals. The concentration of a solution for disinfecting garden tools or treating seeds can vary significantly. If the dosage is violated, there is a risk of negative consequences for plants.

Characteristics and mechanism of action

From the point of view of chemistry, potassium permanganate is a potassium s alt of manganese acid. It is designated as KMnO₄. Also, the drug is often called potassium permanganate.

In industry, manganese is obtained from ores, and s alt is obtained by oxidizing compounds of this substance. In appearance, the drug resembles beautiful crystals of a dark purple hue. They mix easily with water.

Potassium permanganate has pronounced oxidizing properties. Due to this, the substance has powerful antiseptic and antimicrobial characteristics. Most often, the composition is used to disinfect garden tools and soil. Also, gardeners often use it to feed plants.

Use area

The drug is actively used in agriculture. The main indications for its use include the following:

• disinfection of containers for planting seedlings;
• treatment of soil for seedlings;
• seed processing;
• disinfection of tubers and bulbs;
• disinfection of the basement or cellar;
• decontamination of greenhouses.

With the help of potassium permanganate, it is possible to cope with a number of fungal and bacterial pathologies. It is used to deal with the following violations:

• powdery mildew;
• grey rot;
• late blight;
• black leg;
• mosaic disease.

Also, the substance helps to cope with various insects. It successfully destroys flies, codling moths, wireworms.

Instructions for use and consumption rate of potassium permanganate

In order for the use of the substance to give the desired results, it is important to strictly adhere to the instructions for its use.

Processing beds

The use of manganese in the garden helps to start the redox processes in the structure of plants and improve their photosynthesis. This allows you to increase productivity and strengthen the immunity of crops.

For the treatment of beds, it is recommended to use a solution with a concentration of 1 or 3%. It should be applied 2 weeks before planting. This helps to disinfect and feed the soil, saturating it with the right substances.

With a deficiency of manganese in the structure of the soil, plants often begin to get sick, as their immunity is greatly reduced. This negatively affects the appearance of plants.

Fruit and berry and vegetable plants can be fed root or foliar. In the first case, 5 grams of the substance is required to fertilize strawberries and vegetables per 1 square meter of beds. For bushes it is worth using 5-10 grams. Fruit and berry trees need 10-15 grams of the product.

When using foliar top dressing, it is worth adding 1 gram of boric acid to 10 liters of water. It is required to apply the substance with a spray gun before flowering and at the stage of fruit set formation.

Soil disinfection

To disinfect the soil, you need to make a solution of potassium permanganate with a concentration of 2%. It must be added to each recess in a volume of 1 liter. This will help to destroy all pathogens that provoke root rot, Fusarium and other diseases. It is better to heat the substance slightly before use.

For seeds and seedlings

Using fertilizer to treat seeds helps to decontaminate them. It should be used for planting material that was collected independently. Shop seeds usually go through all the necessary processing.

Using potassium permanganate helps get rid of all pathogens. To do this, make a solution with a concentration of 1% and place the seeds in it for half an hour. Then they need to be washed with plenty of water and dried.

Also, potassium permanganate can be used to disinfect containers for seedlings. To do this, the containers must be thoroughly rinsed with a solution of potassium permanganate with a concentration of 2-3%.

In the greenhouse

Spraying the greenhouse helps to get rid of all the pathogens that accumulate on its walls. The procedure must be carried out before the start of landing work. In this case, the frame must be thoroughly washed with a solution of potassium permanganate.

For indoor plants

Manganese for home flowers should be used in the spring. This is done at the stage of awakening plants after a dormant period. It is recommended to combine the composition with boric acid. To make an effective working solution, you need to mix 3 grams of potassium permanganate and boric acid with 10 liters of water. The composition is suitable for spraying foliage or moistening the soil in pots. Small plants require 500 milliliters of the product, large flowers - 1 liter of the substance.

If symptoms of chlorosis are present, a manganese or iron deficiency may be suspected. Moreover, the signs of these violations usually coincide. To increase the efficiency of processing, it is worth combining these elements, since they work in pairs, reinforcing each other.

Bulbous plants are recommended to soak before planting in a solution that includes boron and manganese. This helps to avoid the development of fungal infections. Bulbs need to be soaked for 2 hours. In this case, the concentration of the solution should be 0.1%.

Precautions

When working with potassium permanganate, you need to consider that the substance can cause burns. Therefore, when using it, you should follow the following rules:

1. Work with potassium permanganate with gloves.
2. It is forbidden to touch the crystals with bare hands. Therefore, they need to be taken with a match or a toothpick.
3. For high-quality mixing of potassium permanganate with water, you should use warm or hot liquid.
4. It is important to mix the composition thoroughly so that the plants do not get burned.
5. Ready solution should be used immediately. The composition cannot be stored.
6. The container with potassium permanganate should be stored in a dark place, out of reach of children and pets.

Terms and rules of storage

It is recommended to keep the drug in a dark glass container. This needs to be done in a cool place. It is important to ensure that it is not exposed to direct sunlight, as this will lead to the loss of oxidizing properties.

It should be borne in mind that potassium permanganate is highly flammable. It is also considered explosive. Therefore, the container with the substance must be placed away from active metals - sodium, calcium, magnesium, aluminum. Also, the drug should not be kept near sulfur or glycerin.

The shelf life of potassium permanganate is 5 years. After this time, its antiseptic properties disappear. The working solution must be disposed of immediately. It cannot be stored for a long time.

Potassium permanganate is an effective tool that is often used in growing plants. The drug has antiseptic and healing properties. It can also be used as a top dressing. In order for the product to give the desired effect, it is important to strictly follow the instructions and observe safety precautions.
