HAIFA BONUS™ 13-2-44
|
An innovative & efficient high-K foliar formulation
Foliar application of potassic fertilizers is a common practice to increase yields and to improve yield quality of fruit trees and other crops. In order to supply plants with adequate dose of foliar-applied potassium, repeated sprays are required. Increasing spray concentration to save on applications may result in leaf scorching. Haifa Bonus™ is a foliar fertilizer developed to enable spraying of highly concentrated solution which reduces the number of applications needed and without scorching of the foliage.

The advantages of potassium nitrate
Haifa Bonus™ formulas are based on Haifa’s Multi-K™ potassium nitrate. Potassium nitrate contains 100% plant macro-nutrients: potassium (K) and nitrate-nitrogen (N-NO3). Plants absorb both the potassium and the nitrate rapidly, in a balanced manner. The similar uptake rates of these two ions improve the movement of both potassium and nitrogen in the plant, thus enhancing plant nutrition. Potassium nitrate is free of chloride, sodium and any other elements which are detrimental to plants.

how haifa bonus™ works -
Haifa-Bonus™ NPK is applied by foliar spray and forms a droplet on the leaf.
|
Portion of the fertilizer is absorbed immediately.
|
When the air gets hot and dry, the fertilizer droplets dries up and nutrient uptake temporarily discontinued
|
At night, the dew re-dissolves the fertilizer and nutrient uptake is renewed

Guidelines for successful foliar fertilization
General
• Spray during the cooler and more humid parts of the day and when wind is low.
• Never spray on plants under stress.
• Test for possible side-effects or phytotoxicity by a small trial, spraying a week prior to the intended commercial treatments.
• After spraying rinse thoroughly the sprayer and all its parts with fresh water.
Preparation of tank mix
• Fill ¼ - 1∕3 of the spray tank with water. Add the fertilizer(s) and then fill the tank with water.
• When preparing tank mix that includes pesticides, it is advisable:
• To keep the pH of the spray solution at level of 5.5 -6.5, in order to avoid alkaline hydrolysis of the pesticides.
• To perform compatibility test of the spray-mix prior to large-scale treatment. To do so, prepare a sample of the spray materials at the recommended concentrations and spray this mixture onto a small area. Wait 4-5 days, and check for phytotoxicity symptoms.
Setting application rates
• Consider both spray concentration and spray volume. If you apply smaller (or larger) volume than recommended, increase (or decrease) the fertilizer concentration of the spray solution accordingly, to keep the total application rate per unit of area. However, take care that the
spray concentration is not too high, as concentrated spray solution may scorch leaves.
• In general, effective foliar nutrition requires application rates of at least 20-40 kg Haifa Bonus per hectare per season.
• Plants in areas of humid climate tend to have thinner leaf cuticle, which make them more susceptible to phytotoxcity. For this reason, spray concentrations must be considered more cautiously in these areas.
