有机柑橘种植中五种溃疡病防治药剂作用评价摘要:通过田间药效试验筛选防治柑橘溃疡病(xanthomonasaxonopodispv.citri)的有效有机药剂,以清水为对照,工农-16型背负手摇喷雾器喷雾,以咪鲜·松、代森铵和叶青双作比较,对比研究了硫酸铜钙、噻菌铜、四霉素、春雷霉素与王铜混配剂、水胆矾和两水硫酸钙结合体等5种杀菌剂对柑橘溃疡病的防治效果。结果表明,硫酸铜钙、噻菌铜防治效果较好,与咪鲜·松相当,四霉素、春雷霉素与王铜混配剂(加瑞农)、水胆矾和二水硫酸钙结合体防治效果较差,低于代森铵和叶青双;首次对上述药剂的抗雨水能力进行了评价,结果表明,加瑞农、咪鲜·松抗雨水能力最强,其次是硫酸铜钙、水胆矾和两水硫酸钙结合体,噻菌铜、四霉素效果较差,代森铵、叶青双最差。试验中各处理均无药害产生。关键词:有机杀菌剂;柑橘溃疡病(xanthomonasaxonopodispv.citri);防治效果effectsoffivebactericidesforcontrollingxanthomonasaxonopodispv.citriinorganiccitrusorchardzhanglai-li1,xianjia-xu2,wudong2,heyong2,maorun-qian3(1.southchinabotanicalgarden,chineseacademyofsciences,guangzhou510650,china;2.luckyteambiotechdevelopment(hepu)co.,ltd.,hepu536100,guangxi,china;3.instituteofentomologyinguangzhou,guangzhou510260,china)abstract:comparedwithprochloraz·copperrosin,ambam,bismerthlazolandwater,theeffectsofcoppercalciumsulphate,thiodiazole-copper,tetramycin,kasugamycinandcopperoxychloridemixture,bordeauxmixtureforcontrollingxanthomonasaxonopodispv.citriinorganiccitrusorchardwerestudiedtofilterouteffectiveorganicmedicamentby16workercarryinghand-typesprayer.theresultsshowedthatcoppercalciumsulphateandthiodiazole-copperhadgoodeffectscorrespondingtoprochloraz·copperrosin.tetramycin,kasugamycinandcopperoxychloridemixture,bordeauxmixturecamethesecondandwereworsethanambamandbismerthlazol.itwasthefirsttimetoassesstheabilityagainstwashingfromrainfalloftheabovemedicament.amongtheeightmedicaments,kasugamycin-copperoxychloridemixtureandprochloraz·copperrosinwerethebest;coppercalciumsulphateandbordeauxmixturecamethesecond.eachtreatmentsintheprocessoftrialsdidn’tproducephytotoxicity.keywords:organicbactericide;citruscanker;controleffect柑橘溃疡病(xanthomonasaxo...
