In fact, most plants treated with Topor display a more vibrant ower as well as darker green foliage. Brief content visible, double tap to read full content. The leading ornamental plant growth regulator (PGR) in the industry, Bonzi keeps plants uniformly compact, hardy, and looking their best. Flurprimidol can be applied as a foliar spray or substrate drench to control plant height, thus resulting in compact plants. Uneven application or over-application may result in irregular or excessive growth control. Madison Heights: 31431. I. If very high ancymidol concentration rates are required, consider evaluating the use of a stronger PGR such as paclobutrazol, flurprimidol or uniconazole to improve results and cost effectiveness.
