Symptoms and causes of damage to tomatoes by late blight

Phytophthora on tomatoes appears in the second half of summer, causing a disease called late blight... It is a fungal disease that affects nightshade crops.

Leaves, stem, and then fruits are covered with brown spots. The inflorescences do not develop, dry up, and soon the entire plantation disappears.

Fungal spores live in the soil, in the remains of leaves, in garden tools, affecting plants every year.

Among the reasons for the appearance of phytophthora are long-term cultivation of a crop in one place, proximity to other nightshades, excessive humidity, damp weather, frequent fogs, abundant dew and too close planting of tomato bushes.

Folk remedies to combat late blight in the greenhouse

To obtain an environmentally friendly harvest, our grandmothers used folk remedies from late blight on tomatoes.

Hydrogen peroxide

Gardeners love this tool for its qualities:

• enriches plants with oxygen;
• has disinfecting properties;
• increases seed germination;
• saturates the root system with air;
• possesses disinfectant qualities.

Due to the content of hydrogen and oxygen molecules in peroxide, the oxidation process occurs when it enters the soil. From this reaction, the pathogenic spores of phytophthora die.

Application of peroxide solution:

1. Soil processing. It is carried out in the spring five days before planting. Pour two liters of solution into the prepared wells. Prepared in the proportion: 6 liters of water - 100 mg of peroxide.
2. Disinfection of seeds before planting with 3% peroxide solution. The seeds are kept for 20 minutes, then dried.
3. To stimulate the growth of seedlings after planting, every week they are sprayed with a solution: 2 liters of water - 4 tbsp. l. peroxide.
4. Adult bushes, cracks, are treated with a foliar and root method with a solution: 2 liters of water, two tbsp. l. drug.

Important... Hydrogen peroxide is diluted in warm water. Tomatoes are processed every week.

Salt

In the garden, it is used as a prophylactic agent in the fight against late blight. Plants after treatment with saline are covered with a thin film, which prevents the spread of phytophthora fungi.

At the first sign of illness, remove damaged leaves and fruits. Then treat the bushes with a salt solution: 10 liters of water, a glass of salt.

Copper wire

The method that gardeners used in the last century: piercing the stem of tomatoes with copper wire. To do this, the wire is calcined, cut into pieces of 3 cm.

The stem is pierced at the base at a distance of 10 cm from the ground. The ends of the wire are lowered without twisting. The plant receives the required amount of copper, which makes tomatoes more resistant to disease.

Attention... Piercing is done when the tomato stalk becomes dense.

Infusion of garlic with potassium permanganate

Garlic and potassium permanganate used in the garden as an antiseptic, with which they fight fungal diseases of tomatoes.At the same time, the tincture is an effective fertilizer that, getting into the soil, stimulates the release of compounds that feed the plant roots. The tops are developing, the tomatoes look healthy and robust.

Solution properties:

• the product has a disinfecting effect;
• heals cracks in fruits;
• saturates the soil with oxygen molecules;
• destroys fungal spores.

Treatment begins before the formation of the first ovaries, subsequent times are carried out every two weeks.

Preparation of the solution: a glass of chopped garlic is insisted for a day in a bucket of water, then 2 g of potassium permanganate is added.

Yeast

Yeast solution - an excellent remedy for the fight and prevention of late blight on tomatoes. The bacteria found in yeast have a destructive effect on pathogenic fungi, saturating the plant with micro and macro elements.

Preparation of a solution from dry yeast:

• we breed a bag of dry yeast in a liter of warm water, the temperature should not exceed 36 degrees;
• add 0.5 liters of old jam or half a glass of sugar;
• mix, pour into a large container and put in a warm place for six hours to ferment;
• dilute the fermented mixture in water up to 10 liters;
• pour a liter of fertilizer under the bush.
