| 中文摘要: |
| 为筛选出对多种花生土传真菌病害综合防治效果理想的种衣剂, 本研究选用7种种衣剂开展了一年两地田间药效试验。结果表明, 7个处理对花生出苗时间和出苗率均无影响, 11%精甲·咯·嘧菌悬浮种衣剂(FSC)对花生冠腐病、根腐病和白绢病具有较好的防治效果, 对两地的3种病害防效可达78.58%以上, 其次为25%噻虫·咯·霜灵FSC, 防效达72.71%以上。与空白对照相比, 11%精甲·咯·嘧菌FSC处理增产率最高, 两地分别增产13.42%和10.25%, 其次为25%噻虫·咯·霜灵FSC处理, 两地分别增产11.83%和10.09%。综合安全性、防治效果、增产效果, 11%精甲·咯·嘧菌FSC和25%噻虫·咯·霜灵FSC具有较好的推广前景, 一次处理可以同时降低花生冠腐病、根腐病和白绢病的危害。 |

| In order to screen the ideal seed-coating formulations for the comprehensive control of a variety of soil-borne fungal diseases of peanut, seven seed-coating formulations were selected to perform the field efficacy test in two places for one year. The results showed that the seven treatments had no effect on the seedling emergence time and rate of peanut. Metalaxyl-M·fludioxonil·azoxystrobin 11% FSC had a good control efficacy against peanut crown rot, root rot and peanut southern blight, with a control efficacy of more than 78.58%, followed by thiamethoxam·fludioxonil·metalaxyl-M 25% FSC with a control efficacy of more than 72.71%. Compared with the blank control, the yield increase rate by metalaxyl-M·fludioxonil·azoxystrobin 11% FSC treatment was the highest, with an increase rate of 13.42% and 10.25%, followed by thiamethoxam·fludioxonil·metalaxyl-M 25% FSC treatment, with an increase rate of 11.83% and 10.09%, respectively, in two places. Based on the comprehensive safety, control efficacy and yield increase rate, metalaxyl-M·fludioxonil·azoxystrobin 11% FSC and thiamethoxam·fludioxonil·metalaxyl-M 25% FSC have a good potential for promotion. One-time treatment can reduce the harm of peanut crown rot, root rot and peanut southern blight at the same time. |
