• IBA can also be applied directly over the top of the crop after sticking. • This method requires a coarse spray that allows some of the solution to run down the stem toward the base of the cutting. • Hortus IBA Water Soluble Salts are the most commonly used product, with rates from 50 to 300 ppm. • Some leaf curl response can occur, but the plants will normally grow out of it prior to shipping.
