Hortus USA: Selection of plant rooting products

The rates for rooting solutions in this website and on the Hortus IBA Water Soluble Salts label are listed as ppm IBA (parts per million IBA). Some books on plant propagation list ppm IBA for their suggested IBA basal quick dip rates. The rate chart below gives the weight of Salts or number of Tablets required make ppm water soluble IBA rooting solutions. Hortus IBA Water Soluble Salts and Rhizopon AA Water Soluble Tablets can be used interchangeably in rates below 1000 ppm IBA; above 1000 ppm IBA use the Salts.

Hortus IBA Water Soluble Salts and Rhizopon AA Water Soluble Tablets rooting solutions can be used in every case where IBA, K-IBA or premix rooting solutions are used.

CONVERSION: ppm IBA to TABLETS to SALTS
• 1 Tablet of Rhizopon AA Water Soluble Tablets (contains 50 mg IBA) which yields 50 ppm when dissolved in 1 liter of water.
• 1/4 gram (0.25 grams) of Hortus IBA Water Soluble Salts (contains 50 mg IBA) yields 50 ppm IBA when dissolved in 1 liter of water.
• 50 ppm IBA,=1 TABLET/liter= 0.25 GRAMS OF SALTS/liter
• Measure salts by weight not by scoop (sold by weight not volume)

The Rhizopon Rooting Guide can be downloaded. The Rooting Guide is the work of Rhizopon b.v. Products included are those manufactured and sold by Rhizopon worldwide. The first pages of the Rhizopon Rooting Guide have basic information in English. The plant variety pages are in Dutch with reference, as available, to the Latin names. The US product name cross reference is shown in the table below. The Rhizopon Rooting Guide is useful to determine the time of the year when cuttings are suitable to be taken. The Selected Rates Guide may be more useful to determine the US products and procedures to use.

The suggestions for the use of Rhizopon AA #1, #2 and #3, Rhizopon AA Water Soluble Tablets and Hortus IBA Water Soluble Salts are based on the outcome of tests and experiments carried out by international testing stations, research centers, scientific publications and Rhizopon and Hortus USA's own research. Testing is essential. Suitable test rates should be used on a small portion of the crop before doing extensive treatment. Select the rate which provides the desired effect. The actual conditions at your facility may not be the same as the place were the data was obtained. You might find highly successful results if you vary the concentrations somewhat from the listed amount.
