Slavol VVL is used for planting fruits and grapevines, as well as for foliar fertilization:

  • Fruits: pomes, stone fruit, berries, and nuts
  • Grapevines
  • Seedlings and cuttings

Plants can absorb substances from the external environment through roots and leaves. Foliar, plants absorb the active substances of pesticides, plant nutrition products, bio stimulators.

How do auxins contained in SLAVOL VVL work?

By foliar application, auxin-indole-3-acetic acid (IAA), which are found in the preparation SLAVOL VVL, reach all parts of the plant through the stomata, over the phloem where they promote cell division and elongation of cells and organs.

Since IAA in these preparations is of natural origin, formed as a secondary metabolite of bacteria, plants instantly react to it as if it were a product of their metabolism. Auxins are growth regulators in plants and participate in all physiological processes in the plant:

  • formation of lateral and adventitious roots (rhizogenesis),
  • trunk development,
  • trunk growth in thickness,
  • leaf development,
  • fertilization,
  • fruit development.


As an effect of the action of these hormones, there is a faster and more massive development of lateral and adventitious roots, faster and more correct differentiation of buds, development of leaves with a larger leaf surface to perform the process of photosynthesis.

Plants sprayed with SLAVOL VVL have stronger roots, higher leaf mass, uniform fruits, and higher yields. SLAVOL VVL prevents the fall and cracking of fruits before harvest, reduces the saprophytes attack in warehouses.

It is also used in the production of planting material for the initiation and formation of adventitious roots of the rootstock, faster healing of the contact surface between the rootstock and the seedling. The concentrations of auxins in these preparations are adjusted to the needs of the plants for which they are intended.

In Slavol VVL, the active substance also consists of living bacterial cells which, when they come into contact with the soil, inhabit the root surface and have a positive effect on the nutrition of plants with nitrogen, phosphorus, potassium, and microelements.

What do auxins work on?

The effects of auxin from SLAVOL VVL are:

  • bud differentiation
  • inhibition of plant aging
  • the appearance of parthenocarpy i.e. pitted fruits (cucumbers, tomatoes, apples)
  • development of female (pistillate) parts of flowers and fruits
  • enzyme activity
  • protein and nucleic acid synthesis

Auxins delay the onset of leaf and fruit decline:

  • in the early stages of abscissa, auxin inhibits leaf fall
  • in later stages accelerates the abscissa process (by inducing ethylene synthesis)

Auxins regulate fruit development:

  • in the early stages of growth, the endosperm is supplied by auxin from the fruit
  • in later developmental stages the embryo

Bacteria that produce indole-3-acetic acid were selected by a special selection procedure. The indole 3 acetic acid found in SLAVOL VVL is of completely natural origin obtained by microbiological fermentation.

In addition to some bacteria, auxins are synthesized by young plant tissues – meristems of shoots, roots, young leaves and pollen, developing fruits, top of roots.

  • Auxins are transported by conducting vessels through the phloem and from cell to cell.
  • Auxins belong to the group of plant hormones that stimulate all physiological processes in plants.
  • SLAVOL VVL contains microorganisms, growth stimulators that create AUXINS in the fermentation process. Indole – 3 – acetic acid (IAA)

Which bacteria does SLAVOL VVL contain?

SLAVOL VVL also includes:

  • NITROFIXATORS – associative bacteria that fix nitrogen.
  • PHOSPHOMINERALIZERS – bacteria that decompose organic phosphorus compound

POMES (Apple, pear, quince, medlar):

Slavol VVL is applied foliar at a dose of 5 l / ha, alone or with regular protection treatments with pesticides (fungicides, insecticides).

1.Over-blooming with 5 l / ha
2. Fruit development after fertilization (hazelnut-sized fruit) with 5 l / ha
3. After June fruit decline with 5 l / ha

4. July-August period with 5l / ha

5. 10 days before harvest with 5l / ha

STONE FRUIT (Peach, plum, apricot…)

Slavol VVL is applied foliar at a dose of 5 l / ha, alone or with regular protection treatments with pesticides (fungicides, insecticides).

1. Over-blooming with 5 l / ha

2. After fruit drop (intensive fruit growth) with 5l / ha

3. Color change – the beginning of ripening with 5l / ha

  4. A few days before harvest with 5l / ha


Slavol VVL is applied foliar at a dose of 5 l / ha, alone or with regular protection treatments with pesticides (fungicides, insecticides). It affects the size of the fruit, more fruits per flower branch, the color of the fruit, earlier ripening of the fruit in 5-10 days.

1. Beginning of vegetative growth (formation of leaf rosette)
2. During flowering
3. After fertilization – fruit size 2-3cm
4. Before harvest
5. After harvesting for root care

FRUIT SEEDLINGS (Planting material)

Slavol VVL is applied foliar during the vegetation. It increases the thickness, height of seedlings, and affects a better formation of the root system.

1. Immersion of planting material (Soak the root of the seedling in 2% solution of Slavol VVL.).
2. Watering after planting (After planting, water each seedling with the remaining amount of solution).
3. Foliar (5l / ha with water consumption of 300-400 liters), several times during the growing season).


Slavol VVL is applied to 5 l / ha alone or with pesticides (fungicides, insecticides).

1. Visible inflorescence formation – overbloom with 5l / ha
2. Intensive berry growth with 5 l / ha
3. Cluster closing phase with 5l / ha
4. Veraison with 5l / ha


What effects SLAVOL VVL achieve on fruits?

⦁ Increased fertilization;
⦁ Larger number of germinated fruits;
⦁ Fruit size increase, better coloration;
⦁ Better differentiation and number of birth buds;
⦁ Increased total yield;
⦁ Smaller number of cracked fruits (cherries);
⦁ Reduced fruit decline.

What effects does SLAVOL VVL achieve on the grapevine?

⦁ Increased fertilization;
⦁ Increased content of total acids and sugars, which in grapevine varieties leads to a harmonious wine bouquet;
⦁ Better shoot formation and maturation;
⦁ Increase in total yield;
⦁ Less looseness of the cluster;
⦁ Larger number and mass of berries.
