摘要:

【目的】明确不同化学药剂和微生物菌剂对马铃薯枯萎病的田间防治效果和产量影响。【方法】试验采用随机区组设计,选用30%甲霜·噁霉灵水剂(600、750、900 mL/hm2)、北农13号种衣剂(33.00、41.25、55.05 mL/hm2)、40%甲基硫菌灵·咯菌腈悬浮种衣剂(300.0、400.5、600.0 mL/hm2)、坤益健微生物菌剂(1 125 g/hm2)、益普微生物菌剂(3 375 g/hm2)为供试药剂,以不施药剂为对照(CK),分析不同处理间马铃薯苗期出苗率、收获期枯萎病防治效果及马铃薯增产量的差异。【结果】不同处理的出苗率与CK相比无显著差异(P>0.05),出苗率均在94.00%以上,表明不同药剂处理并未抑制马铃薯的出苗。化学药剂30%甲霜·噁霉灵水剂 900 mL/hm2喷淋、北农13号种衣剂55.05 mL/hm2拌种对马铃薯枯萎病防治效果较好,防效分别为66.70%和64.60%;坤益健微生物菌剂和益普微生物菌剂拌种的防效分别为59.66%和58.00%。30%甲霜·噁霉灵水剂900 mL/hm2处理和坤益健微生物菌剂处理的增产效果最好,增产量分别为289.03、202.95 kg/hm2,增产率分别为19.50%、15.28%,而40%甲基硫菌灵·咯菌腈悬浮种衣剂300.0 mL/hm2处理增产效果最低,增产量为60.03 kg/hm2,增产率仅为3.70%。【结论】供试药剂对马铃薯安全;30%甲霜·噁霉灵水剂900 mL/hm2喷淋、北农13号种衣剂55.05 mL/hm2拌种和坤益健微生物菌剂1 125 g/hm2拌种对枯萎病的防治效果较好且马铃薯增产率较高,可作为防控马铃薯枯萎病的药剂。

Abstract:

【Objective】To clarify the effects of various chemical and biological agents on potato Fusarium wilt and yield in field.【Methods】In a randomized blocks design,30% metalaxyl-hymexazol AS(600,750,900 mL/hm2),Beinong No. 13 FSC(33.00,41.25,55.05 mL/hm2),40% thiophanate-methyl·fludioxonil FS(300.0,400.5,600.0 mL/hm2),Kunyijian microbial agent(1 125 g/hm2)and Yipu microbial agent(3 375 g/hm2) were set as test treatments and no treatment as control. Seedling emergence rate,disease control efficacy and yield were investigated and the traits differences were analyzed by software.【Results】There were no significant differences among treatments and the control(P>0.05),with all seedling emergence rate over 94.00% indicating no inhibition on patoto. 30% metalaxyl-hymexazol AS in 900 mL/hm2 spray treatment and the seed dressing treatment of Beinong No. 13 FSC in 55.05 mL/hm2 showed best control effect on the disease,with the control efficiency of 66.70% and 64.60%,respectively. The control efficiency of Kunyijian microbial agent and Yipu microbial agent were 59.66% and 58.00%,respectively. 30% metalaxyl-hymexazol AS in 900 mL/hm2 spray and Kunyijian microbial agent treatment showed the biggest yield promotion effect with yield increased at 289.03,202.95 kg/hm2 and yield promotion rate at 19.50% and 15.28%,respectively. While yield and yield promotion rate of 40% thiophanate-methyl·fludioxonil FS in 300.0 mL/hm2 were 60.03 kg/hm2 and 3.70%,respectively.【Conclusion】The agents were safe to potato. The spraying treatment of 30% metalaxyl-hymexazol AS in 900 mL/hm2,seed dressing treatment of Beinong No. 13 FSC in 55.05 mL/hm2,and seed dressing treatment of Kunyijian microbial in 1 125 g/hm2 showed higher control efficiency and yield promotion effect which will be effective agents for potato Fusarium wilt control.
