| 中文摘要 | 在永靖及溪湖比較經濟安全用藥及一般用藥,分別對芥藍菜及花椰菜 上小菜蛾之防治效果及防治成本之試驗。經濟安全用藥區依蔬菜生育期、蟲口密 度決定施藥與否及藥劑種類;一般用藥區依農民習慣自行決定施藥時期及藥劑種 類。結果顯示,單位面積同為0.1公頃,經濟安全用藥區平均用藥量441公克, 防治成本396元,施藥次數4.66次,每次用藥種類平均1.78種;一般用藥區平 均用藥量1588公克,防治成本1341元,施藥次數6次,每次用藥種類平均2.94 種;但二者防治效果並無差異,採收前經生物檢定分析,殺蟲劑殘留量均屬零級。 |
| 英文摘要 | This experiment was carried out in the vegetable field of central Taiwan to compare the economic and safe application of insecticides and control costs for diamond back moth, Plutella xylostella L. Results showed that the dosage of economic and safe application field and common field with the same control efficacy was 441 gm to 1588 gm per 0.1 ha, and the control cost was NT$ 396 to 1588 per 0.1 ha, respectively. Results indicated that farmers tend to use the mixtures of pesticides at the concentrations higher than the recommended rate and disregard the necessity of economic and safe application of insecticides, therefore, some pertinent education must be strengthened. |
