Occurrence of Anthracnose on Fruits of Asian Pear Tree Caused by Colletotrichum acutatum
Anthracnose symptoms often occurred on fruits of Asian pear trees grown in Anseong, Naju, Seonghwan and Pyeongtaek in Korea during the harvesting period from 2000 to 2005. A total of 28 isolates of Colletotrichum sp. were obtained from the anthracnose symptoms. All the isolates were identified as Colletotrichum acutatum based on their morphological and cultural characteristics. Four isolates of...
متن کاملStrawberry Anthracnose: Histopathology of Colletotrichum acutatum and C. fragariae.
ABSTRACT Ontogeny of the invasion process by Colletotrichum acutatum and C. fragariae was studied on petioles and stolons of the strawberry cultivar Chandler using light and electron microscopy. The invasion of host tissue by each fungal species was similar; however, each invasion event occurred more rapidly with C. fragariae than with C. acutatum. Following cuticular penetration via an appress...
متن کاملPre- and Post-Infection Activity of Pyraclostrobin for Control of Anthracnose Fruit Rot of Strawberry Caused by Colletotrichum acutatum
Strawberry anthracnose, caused by Colletotrichum acutatum J. H. Simmonds, is one of the most serious diseases in commercial strawberry production. Even in well-managed fields, losses due to the fruit-rotting phase can exceed 50% when conditions favor disease development (10). Historically, the disease has been thought of as a “southern” disease (16), occurring primarily in the warmer production...
متن کاملApplication of Rhizobacteria for Plant Growth Promotion Effect and Biocontrol of Anthracnose Caused by Colletotrichum acutatum on Pepper
In vitro and greenhouse screening of seven rhizobacterial isolates, AB05, AB10, AB11, AB12, AB14, AB15 and AB17, was conducted to investigate the plant growth promoting activities and inhibition against anthracnose caused by Colletotrichum acutatum in pepper. According to identification based on 16S rDNA sequencing, the majority of the isolates are members of Bacillus and a single isolate belon...
متن کاملOccurrence of Anthracnose on Chinese Mallow Caused by Colletotrichum malvarum
