中文摘要：

8种根部淋施杀菌剂对节瓜枯萎病的防治试验结果表明，第3次施药后10d，50％多菌灵可湿性粉剂l000倍、68％精甲霜．锰锌水分散粒剂1000倍、62．5g/L精甲·咯菌腈种衣剂1500倍和99％恶霉灵可湿性粉剂3000倍对节瓜枯萎病的平均防效分别为86．O％、50．5％、18.3％和8．2％，而50％咯菌腈可湿性粉剂1700倍、50％腐霉利可湿性粉剂1000倍、20％噻菌铜悬浮剂800倍和240g/L噻呋酰胺悬浮剂1500倍对节瓜枯萎病没有表现出防效。因此，对节瓜枯萎病有较好防治效果的药剂为50％多菌灵可湿性粉剂，其次为68％精甲霜·锰锌水分散粒剂。

英文摘要：

To screening the fungicides against chieh-qua Fusarium wilt, the eight fungicides were drenched on the roots of chieh- qua respectively. The field test results showed that the control efficiency of 50% Carbendazim WP with diluted 1 000 times, 68% Metalaxyl-M mancozeb WG with diluted 1000 times, 62.5% Metalaxyl-m fludioxonil FS with diluted 1 500 times, 99% Hymexazol WP with diluted 3 000 times, were 86.0%,50.5%,18.3% and 8.2%, respectively at 10 d after the third spraying, but all of 50% Fludionil WP with diluted 1 700 times, 50% Procymidone WP with diluted 1 000 times, 20% Thiodiazole-copper SC with diluted 800 times and 240 g/L Thifluzamide SC with diluted 1 500 times had no control efficiency against chieh-qua Fusarium wilt. Therefore, 50% Carbendazim WP had a best control efficiency against chieh-qua Fusarium wilt, and the next was 68% Metalaxyl-M mancnzeb WG.
