Taiwan Agricultural Chemicals and Toxic Substances Research Institute (TACTRI) was established in January 1st, 1985. TACTRI arose from the previous Taiwan Plant Protection Center (TPPC) that was cofounded by United Nations Development Program and Republic of China (ROC) government in 1971. Since ROC withdrawal from UN, TPPC was completely funded by ROC government. In 1985, in efforts to recognize the research achievements in safe and minimal use of pesticides, the Center was transformed into TACTRI, a governmental research institute under the subjection of Provincial Department of Agriculture and Forestry (PDAF). After readjustment of government structure and function in 1999, TACTRI was under the subjection of the Council of Agriculture, Executive Yuan.
