蘆筍病害發生與防治之研究(第二年)

Abstract

(1)田間殘留根際之枯老病枝為蘆筍病害主要感染源，並可使幼苗引起苗枝枯，又病苗將病害蔓延及各產地。 (2) 田間防治以完全根除枯老病莖，並在新留母莖時施藥防治始可收效。供試殺菌劑中，以萬力可濕性粉劑對莖枯病之效果最好，腐絕可濕性粉劑對褐斑病之效果最好。 1.The condia of the diseased mother stem were the inoculum source of the major stem blight disease of asparagus in fields. 2.Eradication of diseased mother stalks and treatments of the young spears with Benlate or Mertect were the effective control method for stem blight of asparagus in fields.
