| 摘 要： | 农药复配制剂的研究对于延长新农药品种的使用寿命、缓解靶标生物的抗性、扩大防治谱、降低防治成本、提高药效和环境安全性等具有重要的意义。为筛选防治白背飞虱的农药增效复配配方,采用稻茎浸渍法测定了8种农药单剂及复配剂对白背飞虱3龄若虫的毒力。利用共毒因子法定性筛选出16组共毒因子大于20的配比,并对其中15组进一步利用共毒系数法定量筛选,得到有增效作用的5组配比,分别为烯啶虫胺与毒死蜱按1∶30配比以及吡虫啉与异丙威分别按7∶40、7∶200、7∶400和7∶1 000配比;其共毒系数分别为112.5、242.1、212.4、638.1、417.7,其中吡虫啉与异丙威按7∶400配比具有最显著增效作用。

| Abstract: | In order to clear the control effects of different fungicides against wheat sharp eyespot and wheat scab, wheat ‘Kaimai 21’was used as experimental material to compare disease control effects of 12 fungicides against wheat sharp eyespot and 11 fungicides against wheat scab in the field and their effect on wheat yield.The results showed that 30% hexaconazole SC 76.5 g/hm2 and 75% trifloxystrobin·tebuconazole WG 168.75 g/hm2 had bet-ter control effects against wheat sharp eyespot.The disease index control effects at jointing stage(the withered white wheat ear control effects at milk stage)were 62.77%(56.21%)and 60.58%(53.45%),respectively.The wheat yield increased by 27.65% and 21.30%,respectively,compared with the control group.48% phenamacril ·tebuconazole SC 432 g/hm2 and 25% phenamacril SC 750 g/hm2 had better control effects against wheat scab. The disease index control effects (the diseased ears control effects)were 70.78% (56.57%)and 68.84%(46.86%),respectively.The wheat yield increased by 25.44% and 24.40%,respectively,compared with the control group.By comprehensive analysis,these fungicides were recommended in wheat production. |
