Systemic growth regulator on the basis of natural growth hormone. It promotes vigorous growth, increases plant resistance to diseases, improves quality of the products.

Active ingredient:

auxins 11 mg/l, cytokinins 0,03 mg/l


soluble concentrate


1 L, 5 L, 10 L, 20 L

Mode of action:

seven types of the auxins which are a part of Kelpak, SL are responsible for cell growth and extension and 12 types of cytokinins stimulate rapid cell division, which generally leads to accelerated growth of plants.

It can be used in tank mixtures with pesticides (except for other growth regulators and herbicides).

Application features

it is better to apply the product at early stages of a development of culture;

do not apply to non-perennial crops after flowering;

it is recommended to use concentration from 1% to 5% when the roots are soaked;

doze rate of a working fluid for ground spraying is 250-300 liters per hectare;

the interval between applications must be at least 14 days;

after opening, the product should be stored for 15 days at the temperature of no more than +15°C;

do not use Kelpak, SL in tank mixtures with herbicides.

Product’s advantages

due to the ratio of auxin and cytokinin 350:1, foliar application of 2-3 liters per hectare accelerates the growth of the root system of the plant during the first 5-8 days after application;

after 9-14 days the increased root system stimulates synthesis of its own cytokinins which are responsible for the growth of the aerial part of the plant. Greater thickness of the stem, a larger number and size of leaves, improvement of photosynthesis and of metabolism, accelerated cell division lead in its turn to increase in yield.
