Tomatoes, like any other crop, are susceptible to diseases. The cause of damage is excess moisture, unsuitable soil, dense plantings and other factors. Tomato processing against diseases is carried out even before planting the seeds. Increased attention is paid to soil condition and seed processing.
One way disinfection of tomatoes is the use of peroxide. It is a safe substance that can be purchased V pharmacy. Under the influence of the drug, metabolic processes are improved and pathogenic bacteria are destroyed.
Benefits of peroxide for plants
Hydrogen peroxide is a colorless liquid with oxidizing properties. Its disinfectant properties have been used in horticulture to combat tomato diseases.
Peroxide has the following effects on tomatoes and soil:
- disinfects any damage on tomatoes;
- after watering, tomato roots receive additional oxygen;
- based on the results of seed treatment, their germination is stimulated;
- by spraying the leaves receive more oxygen;
- harmful microorganisms contained in the soil are eliminated;
- prevention of late blight and other diseases.
Hydrogen peroxide (H2ABOUT2) cannot be distinguished externally from water. It is a clear liquid that has no tint or impurities. Its composition includes oxygen and hydrogen. However, peroxide, compared to water, contains an additional oxygen atom.
Hydrogen peroxide is an unstable compound. After the loss of an oxygen atom, the substance has an oxidizing effect. As a result, pathogens and spores that cannot withstand contact with oxygen die.
Due to its oxidizing effect, peroxide helps improve the quality of water intended for spraying and watering tomatoes. This substance oxidizes chlorine, organic matter and pesticides.
N2ABOUT2 found in rainwater enriched with ozone. Thus, natural cleansing of the soil occurs. Ozone is an unstable compound and easily breaks down and becomes part of water.
Tillage
Most viruses that cause tomato diseases are found in the soil. Therefore, before planting, it is recommended to treat the soil with hydrogen peroxide.
Tillage can be done not only before transferring seedlings to a greenhouse or open ground, but also after it. Before planting, the soil is watered with water with the addition of 3% of the drug.
Tomatoes prefer loose soil: loamy, sandy loam, neutral or chernozem. If necessary, the soil is enriched with compost, river sand or humus. In autumn, organic fertilizers, potassium and phosphorus are added to the soil. In spring it is useful to feed the soil with nitrogen.
Treatment with peroxide is carried out in the spring a few days before planting.The soil is watered with a solution in each hole intended for planting tomatoes.
Watering tomatoes
A similar composition is used for watering tomatoes. Rainwater is more preferable for plants than tap water. However, when the atmosphere is polluted, rainwater contains more toxins than beneficial substances.
Watering seedlings with peroxide is widely practiced in the USA and European countries. As a result, the crop yield and its resistance to diseases increase.
Due to soil aeration, the root system of plants better absorbs beneficial microelements. When oxygen is released, harmful microflora in the soil is destroyed.
When watering, the thin roots of plants may not withstand the effects of peroxide. However, strong roots will receive the necessary disinfection.
When watering tomatoes with peroxide, you must follow the following rules:
- moisture must penetrate to a depth of more than 10 cm;
- warm water is used;
- when watering, water should not erode the soil or fall on the leaves;
- moisture should be supplied rarely, but in large quantities;
- tomatoes do not tolerate dry soil well;
- the procedure is performed no more than once every week;
- For watering, choose morning or evening time.
Seed treatment
Hydrogen peroxide is used to treat tomato seeds. Due to this procedure, the germination of plants is improved and harmful microorganisms are destroyed.
Tomato seeds are placed in a preparation with a concentration of 10% for 20 minutes. Then they need to be washed with water and dried thoroughly.
To increase the germination of seed material, it is placed in peroxide for 12 hours. For this, a 0.4% solution is used.
After processing, the seeds are washed and dried well. After treatment, tomatoes sprout faster, their yield increases, and the protective functions of seedlings are activated.
Seed disinfection allows you to avoid tomato diseases at an early stage. Most lesions that affect tomatoes are fungal in nature. Spores can remain in a passive state for several years.
After treating seeds with peroxide, the likelihood of developing diseases is significantly reduced. When exposed to the drug, the seed coat is destroyed, which stimulates further growth of tomatoes.
Other solutions are used to soak tomato seeds:
- a glass of water and 10 drops of 3% hydrogen peroxide;
- soaking in 3% peroxide for half an hour.
Plant seeds contain inhibitors that slow down their growth. When peroxide acts, the inhibitors are eliminated, and the tomatoes begin to actively develop.
Processing of seedlings
Tomato seedlings needs additional incentive, which will ensure further development of plants. For watering and spraying seedlings, a composition is used that includes 2 tablespoons of peroxide (3% concentration) and 1 liter of water.
You can water the seedlings with peroxide on an ongoing basis, but not more than once a week. After such feeding, tomatoes begin to actively grow within a few hours.
Treatment of adult plants
Peroxide allows you to disinfect tomato wounds. After applying this substance, the fracture or crack is covered with latex.
Regular spraying of plants helps to avoid the development of fungal diseases.To do this, 1 liter of water requires 20 ml of peroxide. This drug is included in the scheme for treating tomatoes against diseases. It can be used at any stage of plant development.
Spraying tomatoes is carried out in compliance with a number of rules:
- morning or evening period is selected;
- a fine spray is used;
- the liquid should fall on the tomato leaves;
- The procedure is not carried out in hot weather, during rain or windy weather.
After spraying with peroxide, tomatoes gain additional access to oxygen. As a result, the leaves and stems of plants, on which signs of disease most often appear, are disinfected.
For preventive purposes, tomatoes are sprayed every 2 weeks. If the first symptoms of disease are detected, then the procedure can be carried out daily.
Treatment for diseases
If signs of fungal diseases appear on the plant, then measures must be taken to eliminate them. Otherwise, the tomatoes and the harvest will be impossible to save.
Treatment of plants includes spraying them with a peroxide solution. As a result, pathogenic bacteria that cause tomato diseases are destroyed.
Late blight
One of the most common diseases of tomatoes is late blight. It is spread by a fungus that persists in the soil, on plant debris, garden tools, and the walls of greenhouses.
Phytophthora spores are activated by high humidity or lime content in the soil, poor ventilation, and temperature changes.
Late blight appears in the form of small spots on the back of tomato leaves. Over time, the foliage of plants turns brown and dries out, and the stems and fruits turn black.
When signs of late blight appear, dilute 2 tablespoons of peroxide per 1 liter of water. This solution was traditionally used to treat the leaves and stems of tomatoes.
Root rot
At high humidity in the greenhouse on tomatoes root rot develops. The lesion covers the root collar, which becomes black. As a result, the plant dies.
Root rot appears on seedlings and adult tomatoes. If the sprouts are affected, the lower part of the stem first becomes thinner. As a result, the seedling receives less and less nutrients, becomes weaker and loses its immunity.
Prevent disease It is possible at an early stage if you treat the seeds with hydrogen peroxide. In the future, harmful spores are destroyed by regular watering and spraying the tomatoes with a solution of water and peroxide.
The affected parts of the plants are watered with a 3% preparation (20 ml of substance per 1 liter of water) and phosphorus fertilizer. The procedure is repeated 2 times throughout the week.
White spot
In the presence of white spot, tomato yields are reduced because the disease affects their leaves. First, light spots with a brown border appear on the lower leaves. Over time, the foliage turns brown and falls off.
The disease is fungal in nature and develops in high humidity. A peroxide solution is used to treat plants. Additionally, preparations containing copper are used. Spraying the leaves is done twice every week.
Conclusion
Hydrogen peroxide is a universal means of combating fungal diseases. The treatment is carried out on tomato seeds, which stimulates their further growth.As plants develop, peroxide is sprayed and added to water for irrigation. An additional property of peroxide is to improve soil aeration. After decomposition of this substance, water is formed, so this substance is completely harmless to the environment.
