Plant growth regulator
Topflor is a plant growth regulator used to control height of bedding plants, perennials and other potted flower crops. It can be applied either as a spray or to the soil as a drench. Topflor is intended to offer a high level of activity, thereby requiring low rates to achieve optimum growth regulation levels. Growers using Topflor may see improved flower quality, minimal to no flower delay or bud lock and darker green foliage.
