中文摘要 | 台灣中部地區菜豆幼株期主要害蟲有根潛蠅(Melanagromyza centrosematis (Kato))、莖潛蠅(Melanagromyza sojae (Zehntner))、小綠浮塵子 (Edwardsiana flarescens (Fabricius))及大豆蚜(Aphis glycines (Matsumura))等,其危 害植株影響幼株生育甚大,播種萌芽後10∼15天內為其防治適期,以2.8%畢芬 寧E.C. 2,000倍、2.8%賽洛寧E.C. 2,000倍或25%乃力松E.C. 1,000 倍等藥劑防 治效果較佳。菜豆開花結莢期主要害蟲為番茄斑潛蠅(Liriomyza bryoniae(Kalt.)) 、二點葉璊(Tetranychus urticae (Koch))、台灣花薊馬(Frankliniella intonsa(Trybon)) 、小綠浮塵子(E. flarescens)及鱗翅目害蟲(Lepidoptera)等,主要危害葉片、花蕾、 豆莢等,以秋作9∼11月族群密度最高。防治前述害蟲,宜於菜豆開花結莢前, 即害蟲密度低時選用下列藥劑一種2.8%畢芬寧E.C. 2,000倍、2.8%賽洛寧E.C. 2,000倍、2.8%第滅寧E.C. 1,000倍、3%蘇力菌W.P. 1,500倍、50%馬拉松E.C. 500 倍或75%賽滅淨W.P. 4,000倍連續施藥防治次。噴藥時可依害蟲發生情形,相互 配合輪流使用,減少抗藥性。菜豆結莢採收期,如遇害蟲密度較高而必需防治時, 宜選用低毒性藥劑,以確保蔬菜無農藥殘留之虞。 |
英文摘要 | In central Taiwan, soybean root miner (Melanagromyza centrosematis Kato), soybean stem miner (M. sojar Zehntner), smaller green leafhopper (Edwardsiana flarescens Fabricius) and bean aphid (Aphis craccivora Koch) are the major insect pests causing serious damage to young plants of kidney bean. Spraying Bifenthrin 2.8% E. C. (at 2,000 times dilution), Cyhalothrin 2.8% E. C. (at 2,000 times dilution) or Naled 25% E. C. (at 1,000 times dilution) within 10 to 15 days after kidney bean germination could control those insect pests satisfactorily. During the flowering and pod-forming stages, serpentine leafminer (Liriomyza bryoniae Kalt.), two spotted spider mite (Tetranychus urticae Koch), eastern flower thrip (Frankliniella intonsa Trybon), smaller green leafhopper (E. flarescens) and some lepidopterous insects are the major insect pests damaging foliage, flower buds and pods. Their population are usually high during autumn crop. Two consecutive sprays with the chemicals such as Bifenthrin 2.8% E. C. (at 2,000 times dilution), Cyhalothrin 2.8% E. C. (at 2,000 times dilution), Deltamethrin 2.8% E. C. (at 1, 000 times dilution), Bacillus thuringiensi 3% W. P. (at 1, 500 times dilution), Malathion 50% E. C. (at 500 times dilution) or Copermethrin 75% W. P. (at 4,000 times dilution), before flowering and pod-forming stages, have proved effective. These insecticides may be used in combination or alternately depending on the occurrence of pests. If chemicals are needed to reduce the insect pests during harvest period, insecticides of low toxicity should be used to avoid residues of chemicals on the vegetable. |
