Trial Rates for foliar Spray Drip Down & Total Immerse Methods

A wide solution trial rate range is indicated for the Total Immerse and Spray Drip Down Methods.
•   Make rooting solutions using Hortus IBA Water Soluble Salts®
•   Your ideal rates will vary according to specific plant variety, season, quality of the cuttings, and local growing conditions.
•   Prior to large scale production, test a few plants at several rates within the range.
•   If foliar application causes phytotoxicity, try basal applications and/or decrease rates.
•   Use the lowest rate to produce the desired effect. Plant cuttings vary in quality.
•   Trial rates shown are from specific lots under the grower’s particular faculty and environmental controls.
•   Your growing facility and plant lots are different; always perform your own trials for your plants and facility.
