Application on sunflower

If treating seeds with the formulation for seed treatment VIMPEL®-K (300-500 g/t) with stimulant properties and complex micronutrient ORAKUL® seeds (1.0-1.5 L/t):
  • increases the germination energy and field germination rate up to 5%, which makes it possible to generate a given stand density of plants;
  • enhances the active development of root system, thus increasing drought resistance by 20-25%;
  • increases vegetative mass of plants and leaf surface area by 16-32%;
  • increases effectiveness of photosynthesis.         

Application of plant growth stimulator VIMPEL® in the phases from 2 true leaves till flowering (application rate 300-500 g/ha): 

  • accelerates the metabolic processes in tissues, plants absorb more intensively food compounds from the soil and from micronutrients when applying foliar feeding, fertilizing effectiveness is increased by 30%;
  • protects plants against pesticide stress in the case of both soil-applied and postemergent herbicides, plants acquire a distinctive green color and proceed growing as soon as in 2 days after the treatment; 
  • increases leaf surface area;
  • increases chlorophyll content, resulting in an increase of photosynthetic efficiency;
  • decreases water-consumption ratio, plants use moisture more sparingly;
  • increases drought and heat resistance; 
  • increases productivity. 

Adding of the complex universal micronutrient ORAKUL® multicomplex (application rate1.0-2.0 L/ha) at this time provides the plant with all the necessary nutrients, regardless of changes in weather conditions or the physiological state of the soil. Besides due to it:

  • decreases water-consumption ratio by 14%;
  • increases the diameter of anthodium;
  • increases weight of 1000 seeds.

Application of micronutrient ORAKUL® colofermine of boron 1.0-1.5 L/ha is determined by increased demand of sunflower in boron. When there is a lack of it, plant growth is inhibited, number of flowers is decreased and fertilization is disordered. Combined application of ORAKUL® multicomplex in the phase of 2nd – 4th pair of true leaves productivity increases up to 360 kg/ha, in the case of adding VIMPEL® - up to 540 kg/ha.

Application of micronutrients ORAKUL® (S, Fe, Zn, Cu, Mn, Mg) is conducted when there is deficiency of the corresponding elements.

According to the data of Ukrainian research institutions:

  • seed treatment: VIMPEL®-K + ORAKUL® seeds and treatment in the phase of 2nd – 4th pair of true leaves VIMPEL® + ORAKUL® multicomplexORAKUL® colofermine of boron and additional treatment in the phase of 6th – 8th pair of leaves VIMPEL® + ORAKUL® multicomplex + ORAKUL® colamine boron increases productivity by 730 kg/ha.

Combined application of stimulators and micronutrients of Dolina Group is an economically justified measure. Those agricultural enterprises, which implemented these formulations into sunflower cultivation technology, get economic return of 6-9 times the cost.
