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

  • 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 minimum effective dose is not less than 2 l/ha;
  • the interval between applications must be at least 14 days;
  • pH of the tank mixture must be no more than 7 (alkaline pH reduces the effectiveness of auxin and loses a part of its properties while turning into weak acid);
  • after opening, the product should be stored for 15 days at the temperature of no more than +15°C as it loses its properties when it stays open for a long time.

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. A large root system means more moisture and nutrients which the plant absorbs, greater resistance to drought and adverse weather conditions and a better recovery after herbicide treatment. 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.
