The Haifa Bonus™ technology
Prolonged Activity | Improved Efficiency | Better Safety
To grant your crops the full benefits of foliar nutrition,
Haifa’s range of products are formulated to remain on the leaves and nourish the plant over time.
The Haifa Bonus™ technology optimizes the adhesion of the fertilizer to the leaf surface and improve its absorption.

How it works
 |  |  |  |
| Haifa Bonus™ foliar nutrition sprayed, and forms droplets on the leaf surface | A portion of the fertilizer is absorbed immediately | When the air gets hot and dry, the fertilizer droplets dry and nutrient uptake temporarily stops | At night, the dew re-dissolves the fertilizer. Nutrient uptake is renewed |
Tips for a successful foliar spray
General
- Spray during the cooler and more humid hours of the day
- Apply foliar spray when the wind is low.
- Never spray 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
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.
- Avoid concentrated sprays, as they might scorch leaves.
- 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.
Preparation of tank mix
- Fill 1/4 - 1/3 of the spray tank with water. Add the entire amount of the fertilizer(s) and then fill up 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, to avoid alkaline hydrolysis of the pesticides.
- Note: In general, Haifa’s foliar products are slightly acidic, requiring lower rates of acid to set the pH of the spray solution.
- To perform a compatibility test of the spray-mix prior to large-scale treatment.
