Abstract
1．本試驗在求以最有效之藥劑（DDT乳劑及BHC乳劑）作最經濟的施藥時期測定。 2．豆潛蠅爲害之嚴重期在生育初期，以1-1,000倍之25% DDT乳劑撒布，自敏豆幼苗出土後七日間始，每10日施藥一次，連續三次可得完全之防治；且促進生育增加產量。如爲害未甚猖獗時，只噴二次，效果亦優。BHC乳劑效果較遜。
1. The present paper deals with the practical and economic application of DDT and BHC emulsions in controlling stem-miner of Legumes. 2. Serious infestation occurred in the early stage of growing period. Treatment with 25%DDT emulsion in the concentration of 1:1000 gave effective control. This should be done by spraying 2-3 times at 10 days interval beginning from 7 days after germination, BHC emulsion is inferior to DDT emulsion.
