I'm not sure what this has to do with agroforestry :-)  perhaps because boron
is phytotoxic???

First find the nature of your problem.  Are your termites subterranean or
drywood?  Drywood termites nest entirely within timber, subterranean ones
need contact with a water source.  I assume you do not have dampwood termites
as for these the remedy is dry the area & replace the wood.  Borates are
water soluble and so little use in damp situations (IMHO).

If you have drywoods (you'll see little pellets of crap all over the place),
then fumigation will kill them.  Electro guns (R) might (again IMHO) and heat
and cold can also be used.  Since they dwell _within_ the wood, painting
boron on the outside won't do much except discourage new colonies.

If you have subterranean termites - write & I'll tell you more, much more!

Good luck
