Abstract
Endrin, gusathion, folidol, trithion, and methyl parathion were tested for control of the paddy borer (Schoenobius incertellus WK) infesting the second rice crop at Shang-tzu-ting in Chia-yi county in 1957.
1. In the treated plots, the percentage of dead seedling and empty panicle were lower than the check. and there were also significant difference between insecticides and concentrated used
2. Yield of rice receiving treatments was higher than that on the untreated plots, but there was significant difference between insecticides and concentrated sprays. Endrin and gusathion gave the best results in controlling this species, as the index of yield were at 20.82% to 38.24%; and 22.65% to 32.72%; in the folidol treated plots as index of yield was 16.25% to 30.00%; in the trithion treated plots as index of yield was 19.00% to 24.50%, in the methyl parathion treated plots as index of yield was 10.80% to 18.10%, therefore the methyl parathion was least effective in controlling this pest in these experiments.
在嘉義山子頂舉行二期作防治三化螟蟲試驗，參加殺蟲劑為19.5% Endrin, 20% Gusathion, 46.6% Folidol, 37% Trithion和44.5% Methylparathion等五種乳劑。
(1) 施藥區與對照區禾苗枯心率和白穗率之差異，均屬顯著，藥劑和濃度間之差異，亦屬顯著。
(2) 施藥區與對照產量之差異，頗為顯著，藥劑和濃度間之差異，尚屬顯著。各試驗區之產量指數Endrin 20.82~38.24%及Gusathion 22.65~32.72%最高。Folidol 16.25~30.00%及Trithion 19.00~24.50%次之，Methyl parathion 10.80~18.10%最低。本試驗中治螟成效，就產量而言，Endrin和Gusathion乳劑最優，Folidol和Trithion乳劑次之，但Methyl parathion乳劑最劣。
