| 为筛选防治小麦赤霉病的新型生物产品及其减药增效配方, 于2016年分别在湖北襄阳和荆州开展田间试验?评价了植物免疫蛋白质生物农药6%寡糖·链蛋白可湿性粉剂?诱抗剂0.5%大黄素甲醚水剂和生物刺激素爱诺森可溶液剂对赤霉病的防治效果, 筛选了上述3种生物产品与常规化学农药430 g/L戊唑醇悬浮剂?25%咪鲜胺乳油和50%多菌灵可湿性粉剂减药增效组合配方?结果表明:6%寡糖·链蛋白可湿性粉剂和0.5%大黄素甲醚水剂处理的防效分别在20.18%~24.37%和18.32%~22.98%之间, 爱诺森处理对小麦赤霉病无防治效果?430 g/L戊唑醇悬浮剂?25%咪鲜胺乳油和50%多菌灵可湿性粉剂等3种杀菌剂减量20%分别与寡糖·链蛋白?大黄素甲醚和爱诺森复配田间防效表明, 50%多菌灵可湿性粉剂减量20%与寡糖·链蛋白?大黄素甲醚和爱诺森3种生物产品复配处理的病情指数在3.34~7.81, 防治效果在63.99%~77.56%, 其增效范围在3.22%~47.59%, 与430 g/L戊唑醇悬浮剂未减药用量的防效相当( P >0.05)?50%多菌灵可湿性粉剂减量20%与寡糖·链蛋白?大黄素甲醚和爱诺森3种生物产品复配处理的产量显著高于未减药的多菌灵处理产量( P <0.05), 增产幅度在3.74%~9.28%之间?30 g/L戊唑醇悬浮剂和25%咪鲜胺乳油减量20%与寡糖·链蛋白?大黄素甲醚和爱诺森3种生物产品复配处理的防效和增产效果趋势不显著? |
| 英文摘要: |
| In order to screen new biological products and related formulations against Fusarium head blight (FHB) for reducing fungicides while increasing efficacy, the effects of plant immune protein oligosaccharins·plant activator protein 6% WP, inducer physcion 0.5% AS and biostimulator Enersol SL were evaluated for controlling FHB in Xiangyang and Jingzhou of Hubei province in 2016. The synergistic formulas of oligosaccharins·plant activator protein, physcion and Enersol with 430 g/L tebuconazole SC, 20% prochloraz EC and 50% carbendazim WP was screened as well. The results showed that the control efficacies of oligosaccharins·plant activator protein and physcion were between 20.18%-24.37% and 18.32%-22.98%, respectively, while Enersol had no control effect on FHB. The control effects of the 430 g/L tebuconazole SC, 25% prochloraz EC and 50% carbendazim WP reduced 20% dosage with oligosaccharide·catenin, physcion and Enersol was conducted. The disease index of carbendazim with 20% reduction mixed with oligosaccharins·plant activator protein, physcion and Enersol was between 3.34 and 7.81, and efficacy was between 63.99% and 77.56%, and the synergy ranged from 3.22% to 47.59%. Furthermore, the control efficacy of oligosaccharins·plant activator protein and physcion was similar to that of tebuconazole without reducing dosage 20% off ( P >0.05). The yield of the treatment of carbendazim with 20% reduction mixed with oligosaccharins·plant activator protein, physcion and Enersol increased by 3.74%-9.28%, significantly higher than the treatment without reduction ( P <0.05). 30 g/L tebuconazole SC and prochloraz 25% EC with 20% reduction mixed with oligosaccharins·plant activator protein, physcion and Enersol showed no significant differences in control efficacy and wheat production. |
