【摘要】 本文研究了几种内吸杀虫剂在烟苗移栽时根施对烟蚜的控制作用．结果表明：４０％久效磷乳油１０００倍液准根３０ｄ失效１９０％ＨＦ１０１２０００倍液灌根、５％和１０％ＨＦ１０１两种颗粒剂３７．５ｋｇ／ｈａ．１５％铁灭克颗粒剂３．７５Ｋｇ／ｈａ和５．５５ｋｇ／ｈａ，施药后５０ｄ防效均在９０％以上．并且不直接杀伤天敌，保护了田间天敌的自然控蚜作用．一次用药可控制整个大田生长期的蚜害问题，克服了目前生产上多次叶面施药和打保险药的现象，节省人力、财力，具有良好的生态和社会效益．更多还原

【Abstract】 Experiments were conducted in Anhui Province during 1992- 1993 to evaluate the performence of three systemicinsecticides in pretransplant soil treatments to control the green peach aphids on flue-cured tobacco, Nicotina tabacum L.HF101 with both transplant water(T. P. W. ) 300ml/hole of concentration 0. 4% and granular preparation applications of5% and 10% in 2. 0g/hole gave excellent control,and remained effective to 50 days (91. 3% - 99. 0% ) after application.The preparation of 15% Temik e. g. aldicarb 0. 2g/hole and 0. 3g/hole provided similar results compaired with HF101, butthe 40% Ozodrin (300 ml/hole ) of concentration 1 : 1000, using with T. P. W. was less effectly to 30 days aftetapplication. This method was safty to nature enemies and would reduce labour and equipment requirements as well asinsecticidal pollution in the air. The author indicated that it appeared to be a good and suitable alternative to numerousspraying applications of insecticides in tobacco fields convertionally.更多还原
