Leaf-dressing is sometimes more efficient and faster than any root application. How is tomato spraying going and what is it for? We will analyze in detail the important points of the agricultural event.
Spraying rules for tomatoes
Why is it needed
Vegetable crops assimilate substances not only through the underground parts, but also through the foliage. In tomatoes, this ability is highly developed. Plants react painfully to the lack of trace elements, temperature changes. At high humidity, fungi are activated, and in heat, the roots can be burned with chemical dressings.
Even the soil well filled with fertilizers before planting is not able to feed the abundantly fruiting tomato bushes until the middle of the season.
Leaf handling is an emergency aid for tomatoes. Fertilizers, stimulants and fungicides enter the cells directly, bypassing the long period of absorption through the soil. The drugs start to work in the first two hours, and not after 10 days, as it usually happens.
Foliar dressing is effective at any stage of crop development. Weakened seedlings better absorb trace elements and quickly acquire a healthy appearance. You cannot do without spraying on the leaf during flowering and fruiting periods: plants absorb only the necessary substances and do not accumulate nitrates.
Nutrition
If vegetables do not develop well and have an unhealthy appearance, then we recommend alternating root and foliar applications. While the nutrients get to the underground parts, the tops will quickly absorb only everything they need. The procedures are carried out in cloudy weather or in the evening, when the sun is no longer so hot.
Deficiency signs
The lack of any of the elements is often accompanied by noticeable symptoms. This is especially evident at the stages of the formation of green mass and fruits. Of course, in each case there are exceptions, but all the signs of shortage are systematic.
- Nitrogen. The foliage turns yellow at the edges, after which it falls off. The veins on the underside of the tops acquire a blue-red tint.
- Magnesium. The disadvantage manifests itself in the form of a plate turned up.
- Phosphorus. The aboveground parts of the plant darken, acquiring a greenish-blue color. The foliage is deformed, the stem becomes brittle, the roots wither.
- Potassium. As with magnesium deficiency, the leaves curl up and turn yellow around the edges.
- Bor. The tops curl up, and the flowers fall off without the formation of ovaries.
- Zinc. Brown gray spots appear on the plant, turning into necrosis. The shape of the plates changes in the same way as with a lack of magnesium.
It is worth remembering that an excess of any of the substances is just as dangerous as a deficiency. nitrogen-containing preparations activate the formation of tops to the detriment of fruits. Tomatoes also have an unpleasant habit of accumulating trace elements in the form of nitrates in the pulp.
Tatiana Orlova (Candidate of Agricultural Sciences):
Iron deficiency (chlorosis) is often confused with nitrogen deficiency. With chlorosis, the leaves also turn yellow. Taking this for a nitrogen deficiency, gardeners begin to intensively give ammonium nitrate or urea. Nitrogen deficiency manifests itself primarily on the lower leaves, i.e. in this case, the leaves of the lower layer turn yellow first, while the tops of the plants turn yellow with iron deficiency.
The beginning of growth
Spraying will help plant development
Nitrogen is the most important component responsible for the absorption of other minerals. With a lack of substance, the plants become pale and thin, the foliage becomes yellow. In advanced cases, the culture drops the ovary and gradually dies.
Spraying tomatoes with a urea solution has a beneficial effect on the development of seedlings. To do this, dilute a teaspoon in a bucket of liquid and pour it into a spray bottle. The procedure is carried out after transplanting to a permanent place of growth and before flowering. Remember that the remedy is contraindicated when tying buds and tomatoes.
Phosphorus assists in the formation of roots and promotes better development of shrubs. With a shortage, the plant stops assimilating nitrogen, which negatively affects the immunity and ripening of fruits. All microelements that a vegetable crop needs are contained in the nitrophoska preparation. A spoonful of the product is diluted in 10 liters of liquid, after which it is applied along the sheet.
Lovers of organic fertilizers are not advised to use for spraying humus. Vermicompost is more suitable for processing tops than manure or chicken droppings. Of course, it is not so concentrated, but after the procedure, the condition of the plants and soil improves.
Flowering and fruiting
As soon as buds appear on the bushes, you must immediately proceed to the next stage. During this period, funds are needed to improve the quality of pollen and ovaries. Boric acid is often used as a microfertilizer, which:
- provides fruits with nutrition;
- saturates the pulp with sugar;
- protects against pests, diseases.
You should not use Borofosk, which is designed for watering under the root of trees. The acid is more economical than fertilizer and leaves fewer marks on the plant. One gram of powder is diluted in 1 liter of hot liquid. On average, 10 ml of solution is consumed per bush. Events are held during the period of mass disclosure of flowers.
To improve fruit formation, wood ash is one of the proven folk remedies. To prepare the extract, pour a glass of substance with boiling water, insist for a day, filter and add to a bucket of water. The resulting solution is thoroughly sprayed with tomatoes - leaves and stems. If you add 20 ml of iodine to the recipe, the ripening of tomatoes will accelerate.
Stimulation
Inside each of the plants there is a specific set of phytohormones that are responsible for growth, flowering or fruit formation. Based on these natural elements, scientists have developed artificial analogues. Biologics in small doses have a beneficial effect on tomatoes. Of course, they are not a substitute for nutritious feeding, but they will help the culture to cope with stressful situations.
Epin
An excellent tool for adapting to unfavorable conditions of detention - sunburn, cold and heat. The advantage of the substance is the absolute non-toxicity for humans and animals, there is no "habit" accumulates in tissues, fruits. For use, it is enough to dilute 10 drops of the drug in a liter jar of water. Since the active elements decompose under ultraviolet light, all work is carried out after sunset.
The procedure is best done in the evening.
"Epin" cannot eliminate the lack of nitrogen, magnesium or potassium, but it will be possible to make the consequences for the plant minimal. Thanks to the stimulant, the planting of seedlings takes place without complications and mass death of seedlings. Do not get carried away with the drug, otherwise the cultures that have been overfed will cease to produce natural hormones on their own.
Zircon
An excellent activator of growth, root formation and flowering, increases resistance to such dangerous diseases as late blight and powdery mildew. Unlike "Epin", this agent accumulates in tissues, therefore the dose and number of sprays must be accurately dosed. Three drops of the medicine are added to a liter of slightly warm water, after which the plants are treated.
Due to the fact that important elements are activated by the sun's rays, the procedures are carried out in the morning. "Zircon" is gradually withdrawn from tomatoes, after which the event can be repeated again. We do not recommend using several hormonal agents at the same time.
Treatment
No matter how many farmers take care of vegetables, one mistake is enough for diseases to appear. Ailments threaten tomatoes starting from seedlings and ending with the ripening period of fruits. It is not enough just to water at the root or sprinkle the chemical on the affected specimens. If you notice the signs of a fungus in time, there is a chance to painlessly and quickly get rid of the disease.
HOM (Chlorine Copper Oxide)
The copper-based preparation resembles the popular Bordeaux mixture in characteristics. The concentrated substance covers the leaf and prevents the causative agent of the disease, which is hiding under the mulch sawdust, from penetrating the plants. Most often used for prevention and treatment:
- late blight;
- brown spot;
- macrosporiosis.
To prevent diseases, dilute 40 g of "HOM" in a bucket of water, mix thoroughly and spray the plants. If you see the first signs of ailment, then the number of treatments is increased. Agricultural work is carried out in the morning or evening, preferably in cool weather without wind. The drug does not have protection from rain, so the measures are repeated after precipitation. Fungicide is prohibited to use during flowering and fruit formation.
Fitosporin
An excellent remedy for combating fungal diseases. Active elements suppress the reproduction of pathogens of late blight and powdery mildew. In addition to poisons, the composition contains humic acids, which have a beneficial effect on the root system. The main advantage of the drug is its low toxicity, which allows it to be used to protect seedlings.
The product can be used to treat plants during flowering and during fruit ripening. The main disadvantage is poor resistance to precipitation. After rain, we recommend to spray again, not forgetting to water the mulching area - around and over the sawdust.
