Atrimmec
This is a plant growth regulator. Has anybody tried this for Bonsai?

Jorge, there has been a couple of discussions obout groth regulators in general, I don't remember if it was this product or not. There are supposedly types that regulate in either way speed up or slow down. I work for a utility and have seen products advertized that slow down a trees growth to where it takes 3 years to get a normal one years growth. Can't say as anyone was using any of these though.

McSpeed:
The product label for this chemical (generic is dikegulac sodium) states it slows down apical growth, promotes new branching and more compact foliage in shrubs and ornamentals. Sounds ideal for some of the species we use in bonsai. It is expensive (about $100 for a gallon) but it might be worth it if it does what it says without killing the tree first. Jorge

I would not use this for bonsai. It reduces growth where you want growth in in a bonsai. You don't want to suppress growth in developing a bonsai, or even in an already developed one.
Growth encourages new shoots and branching to develop. Pruning new growth, once it has matured, is the surest way to get additional ramification and tighter foliage. Applying this would slow that down and slow your work considerably, I would think. |

Thanks Mark. According to their claim, it actually promotes ramification. They claim it produces a "chemical pinching". I'm not sure why a chemical pinch would be better than the cheaper manual version though...

Here's the link.

No, it is not. This link is about Bouganvilea but they do mention the use of this product by some Bougie growers...

"Atrimmec (dikegulac sodium, PBI Gordon) is a compound that interferes with terminal growth by inhibiting deoxyribonucleic acid (DNA) synthesis which is required for new growth. By primarily inhibiting terminals, apical dominance is reduced which enhances the production of lateral branches. This mode of action tends to cause a delay in the resumption of plant growth that may add 2 to 4 weeks to production time. Atrimmec is labeled for use on containerized and landscape woody ornamentals, but also is labeled for use on some hanging basket plants and groundcovers. Of particular interest to perennials growers is its label for lantana (Lantana camara) (750 to 1500 ppm) and butterfly bush (Buddleia) (530 to 1500 ppm). Atrimmec should be applied to actively growing plants with at least two nodes to provide sufficient lateral development. In addition to creating a more full plant, enhancing the number of laterals in a pot generally reduces the overall height of the plant due to the greater distribution of resources. Responses are very species specific so test several rates under your growing conditions. Atrimmec usually causes leaf chlorosis which can be very persistent at higher rates (above 1500 ppm). Other phytotoxic responses, including malformed flowers, have been noted at higher rates on perennials such as gayfeather (Liatris spicata)."
This is a quote from one of the above links...
