Chemical thinning of radiata pine.

P. Maclaren , G. Baker , M. Dean and A. Straker



New Zealand trials using metsulfuron (Escort) and glyphosate (Roundup) for chemical thinning of radiata pine have shown little indication that chainsaws are likely to be replaced as a method of thinning-to-waste. New chemicals, or new formulations of the same chemicals, could reverse this conclusion. In the meantime, chemical thinning-to-waste may have application in very limited situations, including regeneration or wilding control.


Keywords: EZJECT, chemical thinning, poison thinning, thinning, glyphosate, metsulfuron, Pinus radiata.
