Soda against aphids on cucumbers: how to apply, how to spray from pests and diseases

Soda from aphids on cucumbers is a reliable, time-tested method and by many summer residents. The solution is used to disinfect seeds, prevent the appearance of fungal, bacterial, viral lesions, and also as top dressing to prolong the growing season, increase yields. The solution is safe at all stages of growth and maturation of the culture.

Benefits of using baking soda on cucumber beds

Baking soda (sodium bicarbonate, sodium bicarbonate) in moderate doses is harmless to the human body, often used in cooking and home medicine.

Summer residents have long appreciated the disinfecting properties of the powder and actively use it in home gardens:

• for the prevention and treatment of fungal infections;
• repelling aphids, insects (together with soap);
• increase in productivity;
• active formation of ovaries, strengthening of seedlings.

The use of the composition on cucumber beds as an insecticide against aphids or fertilizer:

• safe for plants, animals and humans;
• economical (a bucket of water requires 2 – 4 tablespoons of the substance);
• efficiently.

Regular treatment prevents early wilting of bushes, the development of late blight, rot, powdery mildew, and the spread of pests.

How baking soda helps in the fight against aphids on cucumbers

Summer residents note that the use of baking soda is one of the fastest, most effective and safest ways to kill aphids on cucumbers. Regular processing repels insects, strengthens bushes, and increases the resistance of cucumbers.

The composition has powerful disinfecting properties, prevents the spread of aphids to healthy bushes.

Using baking soda for aphids on cucumbers

Harvesting cucumbers begins about 45 days after germination. Less than a week passes from the ovary to serving the vegetable on the table. In such conditions, the use of chemicals is not safe.

In what cases can cucumbers be treated with soda from aphids

Baking soda replaces insecticides for summer residents to control aphids, spider mites and other pests on cucumbers. Its use is safe, it does not accumulate in fast-growing fruits, and also does not cause any harm to humans.

The powder is most effective in the early stages of pest and infection control. If the disease is running, potassium permanganate, laundry soap, iodine, copper sulfate are added to the solution.

How to dilute soda for processing cucumbers from aphids

To protect cucumbers from aphids, 30–50 g of powder is dissolved in a bucket of water. The concentration depends on the degree of infection of the plants.

For the solution, settled or filtered water is used, heated to 26 – 28 degrees. First, soda is diluted, then other ingredients are added: potassium permanganate, soap, hall, iodine. All ingredients are carefully measured and weighed, monitoring the exact dosage.

Before treating plants from aphids, the composition is shaken again, while it is important that the powder is completely dissolved in water without sediment. The remaining lumps of soda are too caustic, they can damage cucumbers.

How to treat cucumbers from aphids with a solution of baking soda

To get rid of aphids, every 3 days the lashes of cucumbers are abundantly irrigated with a soda composition. If the bushes are weakened, they began to turn yellow, they additionally make basal, more concentrated top dressing.

For successful processing of cucumbers, it is important to follow certain rules:

1. Spraying is carried out in calm weather, early in the morning or in the evening, when the heat subsides.
2. For irrigation, special sprayers are used. The finer the spray, the more uniform the treatment of the bushes will be.
3. Sodium bicarbonate begins to be applied before the aphid covers all the lashes and causes significant damage to the crop. To deter pests, not only the affected bushes are sprayed, but also healthy ones growing in neighboring beds.
4. The solution does not work immediately. If the first treatment did not work, do not increase the concentration. It often takes 2 to 6 weeks to control aphids.

How to get rid of spider mites on cucumbers with soda

The spider mite is active in dry, hot weather, during the formation of ovaries on cucumbers. You can recognize the pest by a light web that entangles cuttings, leaves, flowers. The plant turns yellow, slows down growth.

To save the crop, use the composition:

• from 3 st. l. sodium bicarbonate;
• 1 st. soap (liquid);
• 1–2 tbsp. l. ash.

The solution is diluted in 10 liters of water, the bushes are treated with 2-3 times a week.

How to apply baking soda on cucumbers against powdery mildew

When infected with powdery mildew, cucumber leaves become covered with a thin white coating. The yield drops, the plant becomes lethargic, weakly forms new lashes and ovaries.

To combat the fungus prepare a solution:

• 3 art. l. sodium bicarbonate;
• 3 – 4 tbsp. l. shavings of laundry soap;
• 10 L of water.

Scourges of culture are sprayed weekly for 1,5 – 2 months.

Cucumbers damaged by downy mildew are treated every 2 to 3 days. This disease is more difficult to diagnose and treat.

If the infection is running, and the fungus has spread to all seedlings, copper sulfate or potassium permanganate is added to the soda solution.

How baking soda helps in the fight against white rot of cucumbers

White rot is a fungal disease that affects shoots, fruits, stems, root systems of both young and old plants. The disease actively develops under conditions of greenhouse cultivation at low temperature and high humidity. Without timely treatment, cucumber lashes wither, cease to bear fruit, and eventually die.

To save the crop in a bucket of water (10 l) dilute 5 tbsp. l. soda. The bushes are carefully sprayed with the resulting composition every 3 days – until the symptoms disappear completely.

How to use baking soda on cucumbers for spots and yellowing of the leaves

The leaves on cucumbers turn yellow with a lack of nutrients, infectious or fungal infections, and improper agricultural practices.

If the exact cause of the problem is unknown, the bushes are fed every other day with a weak solution of baking soda (1 tsp per 10-12 liters of water), pouring it under the root.

Rules for the use of baking soda as a top dressing

Cucumbers are fed with soda at least 3 times per season.

The first time the bushes are processed 14 days after planting seedlings in open ground. This contributes to the active formation of ovaries, the strengthening of young shoots.

Two weeks later, top dressing for cucumbers is re-applied to increase the yield and resistance of the plant to pests and diseases.

In the future, the beds are sprayed with a weak solution (1 tablespoon per bucket of water) once a week.

To protect plants and extend the growing season, summer residents use popular folk compositions.

Soda with ash and soap against aphids

To prepare a solution for aphids, you will need:

• 4 tbsp. l. soda powder;
• 2 st. ash;
• 1 crushed bar of laundry soap;
• 10 L of water.

The ash is pre-infused for a day, then the rest of the ingredients are added. Cucumbers are sprayed every 7 to 10 days during the period of active growth.

Soda with iodine.

The composition has a strong antimicrobial effect, helps in the fight against aphids, powdery mildew, late blight.

Dissolve in a bucket of water:

• 50 – 70 g of soap;
• 2 tbsp. l. soda;
• 1 tsp iodine.

Cucumbers are processed once a week, until the symptoms of diseases disappear.

Soda with laundry soap.

A solution with laundry soap helps to quickly get rid of insects, protect crops from larvae and aphids.

For its preparation take:

• 1 bar of soap;
• 2 tbsp. l. soda powder;
• 10 L of water.

To increase the effectiveness of the composition when infesting a large area with pests, a few crystals of potassium permanganate are additionally added (to a pale pink solution).

To extend the growing season, use a composition of 3 tbsp. l. soda in a bucket of water. Cucumbers are fed 3 times during the summer: in early and late July, in mid-August.

Application rules

In order to achieve positive dynamics and visible results when treating cucumbers with soda against aphids, it is important to accurately calculate the dosage, follow the feeding schedule, and monitor the reaction of the plants.

The concentration of an aqueous solution of sodium bicarbonate depends on the purpose of its use:

• for foliar top dressing, a 0,5% solution is used (approximately 2 tablespoons of dry matter per 10 liters of water);
• spraying from insects – 1%;
• formation of ovaries – 3%;
• top dressing during wilting – 5%.

Exceeding the recommended norms will lead to a burn of the roots and leaves.

When prophylactically treating cucumbers from aphids or applying soda as a fertilizer, it is important to follow the chosen scheme. Too frequent spraying will lead to alkalization of the soil, slow wilting, reduced yields, and death of shoots. Rare – will not give any results.

If the recommendations are not followed, sodium bicarbonate can destroy both young shoots and already adult fruit-bearing bushes. If the growth of the lashes has slowed down, flowering and the formation of ovaries do not occur, the plant has become lethargic, it has begun to turn yellow, soda application should be stopped immediately.

Conclusion

Soda from aphids on cucumbers is a natural, reliable, economical way to save the crop. Regular spraying helps not only to get rid of pests, but also to prevent the appearance of rot, powdery mildew, late blight, to prevent early wilting, a drop in crop yields. Soda strengthens the bushes, increases their resistance to diseases, promotes active growth and fruiting. The main advantage of the tool is its safety. After processing the plant from aphids, fresh cucumbers can be served at the table the very next day.
