SHAO Chuang,JIANG Mingliang,ZHANG Jingpeng,et al.Durability of Treated Masson Pine with Hexaconazole Formulations in Field Stake Tests[J].Chinese Journal of Wood Science and Technology,2025,39(03):58-62. DOI: 10.12326/j.2096-9694.2025010.
In order to evaluate the field durability of treated masson pine with hexaconazole (Hex) and CuH
respectively
according to the National Standard GB/T 27655—2011“
Method of evaluating wood preservatives by field tests with stakes
”
the wood samples were impregnated with Hex micro emulsions through the vacuum process. The decay and termite resistance indexes of Hex and CuH treated wood were calculated
the natural durability was determined. The results showed that at Beijing field test site
located in medium biological hazard zone (Z2)
the decay resistance indexes of all CuH treated Masson pines were 10 after 10 years at the retention level of 1.96~2.92 kg/m
3
; and the decay resistance indexes of all Hex treated wood were above 9.0 after 4 years at the retention level of 0.052~0.131 kg/m
3
. At Guangzhou test site
located in severe biological hazard zone (Z4)
the decay resistance indexes of all the Masson pine treated with CuH were above 9.85
and the termite resistance indexes were above 6.10 at the retention level of 2.37~2.94 kg/m
3
after 10 ye
ars. The durability of Masson pine treated with CuH was equivalent to that of treated with cupraamine / ammonia / tebuconazole / propiconazole (CuPT) at the same retention levels in both Z2 and Z4.
