An appraisal of anti-sapstain chemicals in Queensland, Australia
L E Leightley
Eleven formulations were tested in the field for effectiveness against sapstain, mould and fungi on Pinus elliottii in Queensland. The commercially used sodium pentachlorophenoxide (0.5% a.i.) and Captafol (0.2% a.i.) performed well. Busan 1009 (0.3% a.i.), Protek T (5.0% a.i.), Woodgard E.S. and E.C. (0.8% a.i.), together with sodium tetrachlorophenoxide (0.5% a.i.) offer potential as anti-sapstain treatments. Protek S (up to 0.6% a.i.), Azaconazole (up to 0.2% a.i.) and copper-8-quinolinolate (up to 0.06% a.i.) were ineffective in protecting against mould and sapstain fungi.
