Re: BAP10 / Mix it yourself?


>I am still a little confused on what BAP-10 is.

BAP-10 is a 10% solution of Benzylaminopurine, or BAP.  That is 
100,000 parts per million.  A ten fold dilution is 10,000 ppm and a 
hundred fold dilution is 1,000 ppm - that would be about 2.5 ml in a 
cup of water.  Research literature suggests 3,000 to 4,000 ppm for 
hosta.  If you dilute 1 ml of BAP-10 into one ounce of water you get 
about a 3,000 ppm solution.  My experience was that concentrations up 
to 10,000 ppm had little or no effect on large plants with one or two 
applications when used as a spray or wipped onto the leaves.  Dropping 
BAP into the leaf axil of sported leaves did induce a few of the 
dormant buds to develop, but you have to repeate it quite a few times. 
One application doesn't do much.  A small amount of DMSO, less then 1% 
is probably helpful.

If you are only interested in producing a small quantity of plants you 
will do just about as well as Rossizing as using BAP and Rossizing is 
free.  A liter of BAP-10 at $175 plus $10 postage can go a long way 
when it is diluted, but the typical home gardener isn't likely to need 
more then 50 ml in a year or even two years.
