The organo phosphoric insecticides as Parathion, PM and Diazinon emulsion con centrations are found most effective to the paddy borer. (Schoenobius incertellus Walker) During the past three years, the emulsions were formulated the province in order to moderate foreign exchanges and furnish assistance to the development of the local industry. Examinations or the local formulated emulsions have to be made to prove whether they are as well effective as those of imports, therefore the experimental works took place at Ta-un, Hsi-ko, and Hsien-kang districts in Chia-yi Hsien from September to December 1957. The resul s were summarized as follows:
1. From the percentage of white head and the yield of rice, there was significant difference between the treated and untreated blocks. It indicated that the applied chemical was very effective for controlling the paddy borer.
2. According to the yields, under the same applied condition, the effectiveness of Parathion and PM emulsions of the local formulation was not less than the Folidol emulsion (Bayer product) and the PM emulsion from Japan.
