Bottom Line: The International Standard for Phytosanitary Measures 15 (ISPM 15) [1] that is adopted in wood packaging protection in Europe is not suitable for tropical countries like Indonesia.The bioassay test was subjected to dry wood termite Cryptotermes cynocephalus Light.The result showed that wood materials treated by 10 ppm Organo-Complex formula gave good results which were indicated by the low consumption and the fast termination of the termites.

ABSTRACT
The utilization of pesticides often leaves residues which potentially pollute the environment. This journal issue has been encouraging some researchers to find an environmentally friendly insecticide by a cheaper wood preservative method. The International Standard for Phytosanitary Measures 15 (ISPM 15) [1] that is adopted in wood packaging protection in Europe is not suitable for tropical countries like Indonesia. Therefore, the treatment by Organo-Complex-based wood preservation, which consists of copper chromium combined with natural organic compounds, is proposed for effective treatment at a lower cost. The bioassay test was subjected to dry wood termite Cryptotermes cynocephalus Light. The result showed that wood materials treated by 10 ppm Organo-Complex formula gave good results which were indicated by the low consumption and the fast termination of the termites. The toxicity analysis of C-C organic compound solution is classified as grade IV (WHO, 2003) [2], or not harmful. Analysis of the residual content four weeks after the spraying treatment showed a significant reduction in the inorganic content (copper chromate complex), in the range of 35%, and in extracts of natural materials (natural extracts), above 80%.

Mentions: Dermal toxicity was tested on mice treated at the dose of 2,000 mg/kg body weight. Within 14 days of observation, there was no mouse mortality or hair loss. Otherwise, there was no abnormal behavior. The skin of mice was normal throughout the test period and we did not observe any abnormal behavior such as skin irritation, redness or other hypersensitivity symptoms. During test observation, the body weight of mice treated by C-C organic compound solution still increased, as reported in Table 4. The macroscopic observations (Figure 3) on visceral organ groups of mice treated with C-C organic compound solution showed changes in anatomical pathology such as congestion in lungs and liver. However, generally there was no damage to organ or tissue, as determined by macroscopic observation, of the visceral organs.
