| 中文摘要: |
| 为筛选防治草莓白粉病的有效药剂,开展大田试验,选用3种复配药剂(200 g/L氟酰羟.苯甲唑SC、43%氟菌.肟菌酯SC、24%苯甲.烯肟SC)、1种生物药剂(0.4%蛇床子素SL)比较防治效果,同时,将200 g/L氟酰羟.苯甲唑SC分别与5% d-柠檬烯SL、80%代森锰锌WP混配,探索增效作用。结果表明,200 g/L氟酰羟.苯甲唑SC 750倍防治效果较好且安全,分别与5% d-柠檬烯SL 500倍、80%代森锰锌WP 500倍混用后,增效作用显著,但是,代森锰锌会在果面留下明显药斑,不适宜在结果期施用；43%氟菌.肟菌酯SC 1 500倍防治效果比200 g/L氟酰羟.苯甲唑SC 750倍低,差异极显著；24%苯甲.烯肟SC、0.4%蛇床子素SL防治效果较低,不适宜用作草莓白粉病防治药剂。 |

| In order to screen effective fungicides to control of powdery mildew in strawberry,field control experiments were carried out. Three kinds of compound fungicides and one kind of biopesticide,which were 200 g/L pydiflumetofen.difenoconazole SC,43% fluopyram.trifloxystrobin SC,24% difenoconazole.fenaminstrobin SC,0.4% osthole SL,were selected to compare the control effect. Meanwhile,5% d-Limonene SL 500 times and 80% mancozeb WP 500 times were mixed with 200 g/L pydiflumetofen.difenoconazole SC 1 500 times to explore the synergistic effect respectively. The result showed that 200 g/L pydiflumetofen.difenoconazole SC 750 times was effective and safe. The synergism of the mixtures of 5% d-Limonene SL 500 times and 80% mancozeb WP 500 times was obvious,but mancozeb left obvious spots on the surface of fruits,so it wasn’t suitable to be applied in fruiting stage of strawberry. The control effect of 43% fluopyram.trifloxystrobin SC 1 500 times was worse than that of 200 g/L pydiflumetofen.difenoconazole SC 750 times,and the difference was very significant. Because of the low control effect,24% difenoconazole.fenaminstrobin SC and 0.4% osthole SL weren’t suitable to control of powdery mildew in strawberry. |
