| 摘 要： | 为明确噻呋酰胺与嘧菌酯混配对马铃薯黑痣病菌Rhizoctonia solani的增效作用及对马铃薯黑痣病的田间防效,采用菌丝生长速率法和田间药效试验测定二者混配组合对其的联合毒力,分别用Wadley法和Abbott法评价混配组合的增效作用,并比较拌种、沟施及苗期茎基部喷淋3种施药方式对黑痣病的田间防效。结果表明,噻呋酰胺与嘧菌酯以质量比3∶1、2∶1、1∶1和1∶2进行混配时抑制马铃薯黑痣病菌菌丝生长的增效系数分别为1.7、2.7、2.5和1.9,其中2∶1和1∶1的混配组合增效作用较为明显。240 g/L噻呋酰胺悬浮剂与250 g/L嘧菌酯悬浮剂1∶1桶混以240 g(a.i.)/hm~2沟施对马铃薯黑痣病的防效优于拌种和苗期茎基部喷淋的防效,沟施方式下对植株黑痣病的防效为65.3%,对薯块黑痣病的防效为71.6%,增效系数为1.1,表现增效作用。表明噻呋酰胺与嘧菌酯有效成分质量比1∶1的混配组合以240 g(a.i.)/hm~2为推荐剂量沟施可有效防治马铃薯黑痣病。
