| 为明确不同药剂对白及上初次发现的两种重要害虫朱砂叶螨Tetranychus cinnabarinus和棘跳虫 Hypogastrura communis的防治效果,筛选高效低毒的杀虫剂,共使用8种药剂在普洱市白及规模化种植基地内进行了药剂试验。结果表明,喷施7天后,防治朱砂叶螨的5种药剂中,20%甲氰菊酯EC 2 000倍液的防效(91.4%)和速效性最优;10%阿维菌素SG 10 000倍的防效(84%)略低于15%哒螨灵EC 2 000倍(85.1%),但无显著差异,为次优;5%苦参碱AS 6 250倍液的防效(23.2%)和速效性均最差。防治棘跳虫的5种药剂中,喷施7天后,10%阿维菌素SG 10 000倍液的防治效(97%)最优、5%苦参碱AS 6 250倍液的防效(41%)最差;5%啶虫脒EC 3 000倍液的速效性最优,70%吡虫啉WG 1 200倍液的速效性最差。综合考量药剂对朱砂叶螨和棘跳虫的持效性、速效性及防治效果,10%阿维菌素SG 10 000倍液是普洱紫花三叉白及重要害虫防治的首选生物防治药剂。 |
| 英文摘要: |
| To screen out pesticides of high potency and low toxicity for controlling the two major pests,Tetranychus cinnabarinus and Hypogastrura communis, first reported on Bletilla striata (Thunb.) Reichb.f., field trials of total 8 agents were conducted in the large-scale planting base in Pu’er. Among the five pesticides for controlling T.cinnabarinus, fenpropathrin 20% EC 2 000 times solution showed the highest last efficacy (91.4%) in the 7th day after treatment and the best fast-acting property. The control efficacy (84%) in the 7th day after treatment of abamectin 10% SG 10 000 times solution was slightly lower than that of pyridaben 15% EC 2 000 times solution with no significant difference, which were the suboptimal agents. Matrine 5% AS 6 250 times solution was the worst in terms of both the control efficacy (23.2%) and fast-acting property. Among the five pesticides tested for controlling H.communis,abamectin, 10% SG 10 000 times solution and matrine 5% AS 6 250 times solution showed the highest (97%) and lowest （41%） control efficacies in the 7th day after treatment, respectively; while acetamiprid 5% EC 3 000 times solution and imidacloprid 70% WG 1 200 times solution were of the best and worst fast-acting properties, respectively. Based on the persistence, fast-acting property and efficacy, the biopesticide abamectin 10% SG 10 000 times solution could be recommended as the first current choice for controlling both of T.cinnabarinus and H.communis in the B.striata plantation in Pu’er. |
