Abstract
番石榴炭疽病是番石榴果實採收期至採收後其中一種重要病害，本研究主要目的在於瞭解目前發生在番石榴園之炭疽病菌族群的主要種類，以及探討這些炭疽病菌族群對核准用來防治炭疽病殺菌劑之敏感性。本試驗於2019–2020 年間至南部番石榴主要產區採集番石榴炭疽病，採集部位包括無病徵葉片及已產生病斑之病果，將15 分離株分別接種至「珍珠拔」果實。Guava anthracnose is one of the important diseases of guava fruit from harvest to post-harvest. The aim of this study is to understand the main species of Colletotrichum that currently occur in guava orchards, and to investigate the sensitivity of these Colletotrichum spp. to the approved fungicides registered for anthracnose management. From 2019 to 2020, symptomless leaves and diseased fruits
of guava anthracnose were collected from the main production areas in southern Taiwan.
