Abstract:

To select effective triazole formulations against wood rot fungi, the inhibition zone test was conducted in this paper. The decay and termite resistant performance of formulations comprising triazoles was evaluated by laboratory sand block test and filed stake test. The inhibition zone test showed that cyproconazole (CY), tebuconazole (TEB) and propiconazole (PPZ) were effective against brown rot fungi (GT) and white rot fungi (TV). The result of laboratory sand block test showed that the rational retention was 200 g·m-3 and 1.0 kg·m-3 respectively for PT (PPZ:TEB=1:1) and CuPT (Cu:PPZ:TEB=50:1:1) at the circumstance of exterior above ground (C3 use class). The result of field test showed that the rational retention should be more than 3.6 kg·m-3 for CuCY (Cu:CY=98.6:1.4) at the circumstance of exterior ground contact (C4.1 use class) whereas the termite is very severe.
