Rooting Powder: Dip cuttings in 1:1000 solution (1 g/L)

Seedling Treatment: Dip seedlings in 1:1000 solution (1 g/L), or fertigate immediately after planting at 1 kg/ha. For home gardens, to a 9 L watering can, add 1 tsp of kelp and water in plants.

To dissolve Tri-Kelp™, it is recommended that you mix the kelp powder by itself in water as the first step. Fill a 20 L bucket with water, then slowly sprinkle the kelp powder in - stirring continuously. A paint stirrer works very well for this. We recommend that you dissolve no more than 500 g of kelp powder in a 20 L bucket to avoid clumping. Mix well for a few minutes until fully dissolved. Filter the liquid prior to pouring into the tank.

Additional applications can be made immediately prior to or following stress periods such as frost or drought. It is preferable to increase the frequency of applications rather than the concentration of the solution.

Where higher water rates are required for good foliar coverage, do not exceed maximum product rate per hectare. Sensitive foliage or plants should be test sprayed prior to full scale application.

Frequencies are a guideline only and can be adjusted according to farm practices and/or in conjunction with crop monitoring. Ensure suitable spray conditions (e.g. temperature, humidity, wind- speed), prior to foliar application.

Compatibility and/or performance cannot be guaranteed when combined with other products. Jar test for compatibility and spray test on small area before wide-spread use.

Read safety directions before use. Store in a cool dry area out of direct sunlight. Do not pre-mix or store in diluted form. Seal lid/cap immediately after use.

Not compatible with acidic inputs. Avoid spraying close to harvest if produce is susceptible to staining.

WARNING: Do not swallow. The dust from this product may act as an irritant. Avoid inhalation and contact with the eyes and skin. Additional information is listed in the Safety Data Sheet. Avoid spillages on floor as product becomes very slippery when mixed with water and may create a hazard.
