摘要
[目的]评价噻呋酰胺拌种对花生病害的防治效果。[方法]通过不同用量240 g／L噻呋酰胺悬浮剂拌花生种仁的方法，研究其对花生苗期根腐病、茎腐病和中期白绢病的控制效果及对花生产量的影响。[结果]在240 g／L噻呋酰胺悬浮剂用量150、300、450 mL／hm2处理中，以450 mL／hm2处理较好，对根腐病、茎腐病防治效果可达66．64％～74．00％，超过两常规对照的49．96％～60．00％。240 g／L噻呋酰胺悬浮剂拌种对防治花生白绢病发生的效果欠佳，但对延缓白绢病发生有一定效果；240 g／L噻呋酰胺悬浮剂拌种对花生具有增产效果，在用量150、300、450 mL／hm2处理中，以450 mL／hm2处理效果更好，产荚果4444．95 kg／hm2，较空白对照增产692．40 kg／hm2，增幅18．45％，两常规对照产荚果分别为4337．55和4357．50 kg／hm2，较空白对照增幅分别为15．59％和16．12％。[结论]试验结果为噻呋酰胺的进一步研究与应用提供了理论依据。
Abstract
Objective] To evaluate the control efficiency of seed dressing by thifluzamide suspending agent on peanut diseases.[Method] Peanut kernel was dressed by different dosages of 240 g/L thifluzamide suspending agent.Its control efficiency on root rot, stem rot and medi-um-term southern blight as well as effect on peanut yield were researched.[ Result] Among the dosage treatments of 240 g/L thifluzamide sus-pending agent, 450 mL/hm2 treatment was relatively good;its control efficiencies to root rot and stem rot reached 66.64%-74.00%, which was higher than the control (49.96%-60.00%).Seed dressing by 240 g/L thifluzamide suspending agent had poor effects on controlling and preventing the southern blight, but had certain effects on delaying the occurrence of southern blight.Seed dressing by 240 g/L thi-fluzamide suspending agent had good effects on the yield increase of peanut.Among the 150, 300 and 450 mL/hm2 treatments, 450 mL/hm2 treatment had relatively good effects with 4 444.95 kg/hm2 pod yield. Compared with the blank control, the yield increased by 692.40 kg/hm2 , enhancing by 18.45%.Pod yields of the two conventional controls were 4337.55 and 4 357.50 kg/hm2 , respectively, which increased by 15.59% and 16.12%compared with the blank control.[Conclusion] This research provides theoretical foundation for the further research and application of thifluzamide.
