中文摘要 | 本試驗以價廉之MIPC為主,混合數種農民慣用之殺蟲劑,在田間混 合後立即噴施,比較其對褐飛蝨之防治效果。從67年初步結果中發現MIPC 1/3 量 + Ethyl parathion 1/3量 + 煤油之藥效,要比MIPC半量 + Ethyl parathion半 量不加煤油者為佳。與各單劑全量也有相似或較佳之效果。68年期不同混合組 配比較中,以MIPC全量 + 煤油為最經濟有效之混合方法,而MIPC半量 + Furadan半量與Furadan全量單劑有相同之防治效果,均可推薦給農民採用。另 MIPC半量 + Cabaryl全量及MIPC全量 + 神通7E油亦有佳效,必要時可混用。 殺蟲劑添加礦物油確可提高藥劑,以MIPC為例,加入0.2%煤油約可增加35∼ 46.8%之藥效,唯同時應加展著劑並充分攪拌。 |
英文摘要 | This experiment was aimed on comparing the effectiveness of tank mixing inexpensive MIPC with severai commonly used insecticides for the control of brown planthopper on rice preliminary results of 1978 showed that the formula consisting of MIPC at 1/3 recommended rate + ethylparathion at 1/3 recommended rate + kerosene was more effective than that of MIPC at 1/2 recommended rate + ethylparathion at 1/2 recommended rate. The former formula was similarly or more effective than each respective insecticide alone at conventivnal recommended rate. In the 1979 experiment, MIPC at recommended rate + kerosene was found to be the most economic and effective mixture, while MIPC at 1/2 recommended rate + Furadan at 1/2 recommended rate was as effective as Furadan alone at full recommended rate. Both of these mixtures, therefook, could be recommended to the farmers. In addition, MIPC at 1/2 recommended rate + carbaryl at recommended rate and MIPC at recommended rate + sun spray 7E oil were also satisfactory, and provided alternative formulae for tank-mixing when necessary. Mineral oils when mixed with insecticides indeed could increase the effectiveness of latter. For instance, kerosene at 0.2% could increase the effectiveness of MIPC by approximately 35-46.8% for brown planthopper control it could be more appropriate when surfactants were added to the tank and fully mixed. |
