Zinc sulphate or copper sulphate can be considered as a substitute for borax, boric acid combination against insect attack in the preservative treatment of rubber wood. It was found that single stage diffusion process after two consequtive dipping in sodium pentachlorophenate and in either zinc sulphate or copper sulphate is equally effective as two stage difusion process, first with sodium pentachlorophenate and then with either zinc sulphate or copper sulphate ER -
