由Lasiodiplodia theobromae 引起之百香果果腐病

Abstract

2017年7月中旬於南投縣埔里鎮大坪頂地區之百香果果園中發現一種新病害，受害果實出現墨綠色至黑色塊斑而外圍有黃暈，病斑易擴大聯結成大範圍灰黑色並呈現凹陷的塊斑，又於塊斑上出現黑色小點（為病原菌之柄子器）。 A new disease caused by fruit rot of passion fruit (Passiflora edulis) was found in major passion fruit production areas at Puli Township, Nantou County of Taiwan in 2017. The infected fruits showed dark green to black patches with yellow halo. The lesions usually enlarged and joined into a large black and sunken patch with the appearance of black dots (the pycnidia of the pathogen).
