Frequently Asked Questions

HELPING FARMERS GROW FOR OVER 40 YEARS

We have compiled a number of questions that are often asked by farmers and end users. Our technical team has over 600 trials to refer to as well as unique insights from farmers and distributors around the globe. Should any of your questions not be answered below please contact our team or head office for more advice:

  • What is so special about the cellburst process?

    Most other seaweed extracts make use of chemicals, heat, mincing or freezing to extract the active elements found in the Kelp. These methods may break down a significant portion of the useful compounds found in Kelp. The unique Kelpak cold Cellburst process extracts all the sensitive ingredients at a cellular level, preserving them, ultimately ensuring an effective, consistent and reliable end product.

  • Do you add any macro- or micronutrients to Kelpak?

    We sell Kelpak in its pure form as a seaweed extract. Small amounts of macro- and/or micronutrients can be added to customers' specifications.

  • Is Kelpak harmful to bees or wild life?

    Kelpak is manufactured using no chemicals and without harmful additives. Toxicology reports indicate no harmful effects on bees, birds, fish or mammals.

  • Are any synthetic hormones added to Kelpak?

    Kelpak bioregulators contain only naturally occuring plant hormones extracted from Kelp. These have no adverse effects on human or animal physiology but are highly beneficial to plant development and health.

  • Will Kelpak alter the hormonal content of my harvest, possibly effecting the end user?

    Kelpak improves plant growth that subsequently improves fruit size and fruit quality as a secondary effect. Kelpak contains natural plant elements that leave no residue on crops and have no adverse effects on humans, even if ingested in its pure form.

  • Why is some Kelpak green and the seaweed itself is brown?

    Kelpak formulated for use in organic farming is light brown in colour much like the actual seaweed. Kelpak formulations containing nutrients are greenish in colour, indicating that these products have been developed to suit specific market requirements.

  • Can Kelpak be applied in combination with other agricultural chemicals?

    Kelpak can be added in a tank mix with most fertilisers, pesticides and other agrochemicals. To maintain the product's performance in spray mixes, keep the pH below 7 and add the Kelpak last. Care should be taken to never dilute Kelpak more than 1:500 for foliar applications and 1:1000 for drip irrigation.

  • Can I use Kelpak in my hydroponic system?

    Kelpak can be applied successfully through hydroponic nutrient flow systems. For optimum effect, we recommend that Kelpak is diluted no more than 1:1000 (1 part Kelpak to 1000 parts of water/nutrient solution). Kelpak should not be applied more frequently than once every 2 weeks and normally not after first fruit for annual crops. It is important to maintain the pH of the water/nutrient solution below 7.

  • Can Kelpak be applied only once per season?

    Applying Kelpak only once in a season may not offer the products' full range of benefits. Kelpak essentially boosts or “wakes up” the metabolism of a plant so that it can grow actively. Therefore, while Kelpak can technically be applied to plants whenever new growth is required, we normally recommend a crop specific program for application. Kelpak’s crop specific application recommendations are based on intensive scientific studies and when followed closely will ensure that you get the best result by applying it at optimal growth stages.

  • Is it possible to ‘over-dose' my crops with Kelpak?

    Kelpak is completely safe to use on plants even in its undiluted form. Recommended dilution rates are based on over 40 years’ worth of scientific inquiry, ensuring that the user gets the best return on investment. It is important however to adhere to our recommended optimal application timings for best results.

  • How long can I keep Kelpak once it is opened?

    After opening, we recommend that Kelpak be stored in a cool, dry area and be used within 1-2 weeks.Since Kelpak is made from a natural source, it is susceptible to microorganisms in the environment. Although these microorganisms may grow on/in Kelpak after opening, the beneficial activity of the product remains intact for long periods of time. However, clogging of irrigation equipment may occur if fungal growth occurs.

  • Can Kelpak be used instead of fertiliser?

    No. Kelpak contains compounds that, when applied to plants, benefit its natural processes improving nutrient uptake, nutrient efficiency, tolerance to abiotic stress, and/or crop quality. Kelpak contains only a small amount of nutrients, and when diluted to the recommended application rates, it will not contribute any significant amount of nutrients to the plant. However, when used alongside traditional spray programs, Kelpak will enhance the effects of fertilisers and other nutrients.

  • Can I apply Kelpak through my center pivot irrigation?

    Although it is possible to apply Kelpak through your center pivot irrigation we recommend not to dilute the concentration of the product more than 0.1%. Since a large volumes of water is required in center pivot irrigation, it might not be economically feasible to apply Kelpak using this method.

  • What is the best time of day to apply Kelpak sprays?

    As with other systematic agrochemicals, Kelpak should be applied at times when both the plant is metabolically more active as well as when environmental conditions are favorable. Too hot or too cold temperatures will reduce optimal absorption by the plant. Wet leaf surface, and applying during extremely dry or humid conditions will also affect absorption negatively. It is therefore ideal to apply Kelpak early in the morning or late in the afternoon (night), when the outside temperature is moderate and wind speeds are below 15 km/h.

  • How do I treat stressed plants with Kelpak?

    Depending on the nature of the stressful environment and the physiological state of the plant, plants can be treated either with a foliar application or with a root drench. For stressed plants that are wilted (salt stress, drought stress, sun scorth etc), we recommend pouring Kelpak at the base of the plant with a watering can at a concentration of 0.5-1%. The stomata of wilted plants are closed and will therefore not absorb any significant amount of Kelpak, when applied to the foliage.
    For stressed plants that are not wilted (hail damage, animal feeding, disease) apply Kelpak as a foliar spray at a concentration between 0.3-0.5%.

  • Do I need to add a wetter / spreader / pH buffer to the Kelpak mix?

    pH buffer: Since plant growth regulators are more active and more readily absorbed at a pH between 4 and 7, we recommend adding a pH buffer when the pH of the spray mixture is above 7.

    Wetter/spreader: It is advantageous to add a wetter/spreader to the spray mix as it increases the area that Kelpak has in contact with the leaf surface.

  • Are Kelpak bioregulators or biofertilisers available in my region?

    Due to stringent and varied regulations, Kelpak bioregulators are only available in certain regions. Please enquire directly with our head office regarding distribution in your area.
