Recommendations for application of plant growth stimulator Vimpel and Orakul microfertilizers on grapes

APPLICATION ON GRAPES

Treatment of grafts, grapestalks and saplings with the formulation for planting material treatment VIMPEL^®-K (2-3% solution) with stimulant properties and complex micronutrient ORAKUL^® seeds (5% solution) results in:

increase of successful grafting percentage and rooting of grapestalks;
active recovery of root system after sapling transplanting;
increase of graft and scion-rooted sapling survival ability.

Treatment of young plantings and mother plants with plant growth stimulator VIMPEL^® (1 kg/ha) 2-3 times during active shoot growth:

increases leaf area and number of leaves;
enhances ramification of yearling plants and diameter of grafted vines;
increases yield of clonal rootstocks;
increases drought and heat resistance;
accumulation of carbohydrates in the annual vine is enhanced, thus improving wintering capability;
enhances the efficacy of pesticides by 20-25%;
promotes bush formation and accelerates period of coming to industrial fruition;
stimulates the process of reproductive bud formation.

Treatment of fruit plantings with plant growth stimulator VIMPEL^® (1 – 1,5 kg/ha) before flowering, after flowering and in softening of berries period:

accelerates the metabolic processes in tissues, increases absorption by trees major nutrients from the soil and micronutrient fertilizers in the case of foliar treatment;
improves photosynthetic activity at the expense of increase of chlorophyll content in leaves;
increases drought and heat resistance;
enhances the biological efficacy of fungicides by 22 – 28 %;
promotes recovery of annual growth after freezing or hail;
increases fruit initiation by 22 – 25%;
accumulation of carbohydrates in the annual vine is enhanced, thus improving wintering capability;
increases productivity, marketability and eating qualities of berries (sugar content increases by 0,8 – 1,5%).

Adding of the complex universal micronutrient ORAKUL^® multicomplex (application rate 2.0 – 5.0 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.

Application of micronutrient fertilizers ORAKUL® colofermine of ferrum (3.0-4.0 L/ha) and ORAKUL^® colofermine of boron (1 – 1,5 L/ha) is determined by an increased demand of orchards in ferrum and boron. Deficiency of ferrum leads to chlorophyll destruction, chlorosis can be observed on young leaves. Boron has a positive effect on plant growth, and improves pollination of flowers.

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

Combined application of VIMPEL^® growth stimulator with micronutrients from ORAKUL^® series in cultivation technology of grapes (application before and after flowering as well as during softening of berries) leads to the highest economic return. Yield increase is from 3800 to 5500 kg/ha with improved quality index.
