Colletotrichum siamense is associated with post-harvest anthracnose of red onion in the Philippines

Onion (Allium cepa L.) is an important crop widely cultivated in the Philippines. In the Philippines, Colletotrichum gloeosporioides sensu lato and C. circinans have been reported to cause anthracnose twister disease and onion smudge, respectively. This study reports C. siamense from anthracnose-inf...
