Configure®, from Fine Americas, Inc. is one of the newest plant growth regulators on the market. Configure® contains the active ingredient N-(phenylmethyl)-1H-purine-6amine (most commonly called benzyladenine or 6-BA); a synthetic cytokinin. Cytokinins are essential hormones for plant growth and development, and are involved in many physiological functions, including the release of lateral buds from apical dominance and the promotion of cell division and differentiation from undifferentiated tissues. Plant responses to Configure® can be strongly influenced by species or variety and a plant’s growth stage. Water and fertilizer management, temperature, light, greenhouse composition, and other cultural practices may also impact plant response. Although Configure® has been shown to be effective on a broad range of crops, it is impossible to ensure an acceptable response in all cultivars. First-time users of Configure® should first conduct trials using recommended label rates on a limited number of plants before initiating wide-scale usage.

Apical dominance is defined as the phenomenon whereby the main stem of a plant is dominant over (i.e., grows more strongly than) side or basal branches. Apical dominance is naturally maintained by a balance of auxin, a plant hormone produced in the apical meristem; and cytokinin, which is produced in the roots. Apical dominance can be interrupted by increasing the ratio of cytokinin to auxin with foliar applications of Configure®. Applications of Configure® have been shown to increase branching and enhance flowering in a wide range of ornamental species, providing fuller and more marketable plants. Use of Configure® may also result in more compact plants. Shorter, more compact plants are likely due to the plant dividing its ‘energy budget’ among a greater number of side shoots.

The main purpose of this guide is to provide growers with general guidelines on optimal use rates and application timings for Configure® on an extensive range of crops. This guide provides information from evaluations conducted by numerous growers and researchers, including: Mara Grossman, Margaret Tackett, John Freeborn, Kevin Harris, Holly Scoggins, and Joyce Latimer; Virginia Tech Dennis Carey, Wayne Buhler, Ingram McCall, and Brian Whipker; North Carolina State University Paul Pilon; Perennial Solutions Consulting Matthew Blanchard and Erik Runkle; Michigan State University Sonali Padhye and Jude Groninger; University of Florida

Stimulating Plant Growth With Configure® One of the newest plant growth regulators (PGRs) on the market is Configure®, from Fine Americas Inc. Configure® is a synthetic cytokinin that is labeled for use on herbaceous ornamental crops to stimulate branching and flower bud initiation. What is Configure®? Configure® is a 2% liquid solution of benzyladenine, a synthetic cytokinin. Configure® is used as a branching agent and to stimulate additional flower bud development. It was introduced in 2007 for use as a foliar spray on Christmas cactus, Echinacea and hosta. In 2008, it was registered in 25 states and it received a supplemental label for experimental use on any annual, perennial, foliage or tropical crop grown in a greenhouse.
