What type of pathogen is colletotrichum Acutatum?
plant pathogen
Colletotrichum acutatum is a plant pathogen and endophyte. It is the organism that causes the most destructive fungal disease, anthracnose, of lupin species worldwide.
How do you identify colletotrichum?
Colletotrichum truncatum was the most commonly isolated species from infected chili fruit and was readily identified by its falcate spores and abundant setae in the necrotic lesions.
What is the common name of colletotrichum Gloeosporioides?
Anthracnose
Pathogen. Colletotrichum gloeosporioides (Anthracnose) is one of the most common Colletotrichum fungal plant pathogens.
How does colletotrichum Acutatum spread?
The spread of C. acutatum in the field is normally via rain-splash dispersal of conidia (Peres et al., 2005); these conidia may be dispersed to new infection sites in a series of consecutive splash-dispersal events on the ground and in the canopy.
What causes anthracnose disease?
Anthracnose is caused by a fungus, and among vegetables, it attacks cucurbits. Anthracnose can survive on infected plant debris and is very easily spread. Like rust, it thrives under moist and warm conditions and is often spread by watering.
Which of the following is the characteristics of Colletotrichum?
Identification and characterization of Colletotrichum species is based on morphological characters such as size and shape of conidia and appressoria, existence of setae or presence of a teleomorph, and cultural characters such as colony color, growth rate and texture (Smith and Black, 1990).
What does Colletotrichum cause?
In India, Colletotrichum causes three types of foliar symptoms, namely leaf blight, shot hole, and irregular leaf spot. Of these, leaf blight and shot hole are widespread and occur on plants of all age groups. Shade regulation is found to be an effective method of control of the disease in Ghana.
What is the scientific name of Colletotrichum?
ColletotrichumColletotrichum / Scientific name
Which is the specific fruiting bodies in Colletotrichum?
Colletotrichum Corda The fruiting body is an acervulus; conidiophores are produced in a dense, even stand on a thin or well-developed stroma. Conidiophores are simple, short, hyaline, producing abundant phialophores.
What is anthracnose fungus?
Anthracnose is a common fungal disease of shade trees that results in leaf spots, cupping or curling of leaves and early leaf drop. In Minnesota, anthracnose is most common in cool, wet spring weather. Anthracnose is not a significant threat to the health of the tree and doesn’t require treatment in most cases.
How can Colletotrichum be prevented?
Prevent Anthracnose
- Plant resistant plants, or buy healthy transplants.
- Plant your plants in well-drained soil.
- Water your plants with a drip sprinkler, as opposed to an overhead sprinkler.
- Keep ripening fruits from touching the soil.
- Remember to rotate your plants every 2 to 3 years.
What is the scientific name for anthracnose?
Glomerella cingulata (anthracnose)
How was Colletotrichum acutatum originally distinguished using morphological characteristics?
Colletotrichum acutatum (in the broad sense) was originally distinguished using morphological characteristics. The primary diagnostic feature was given as the possession of fusiform conidia with acute ends ( Simmonds 1965 ).
Where does Colletotrichum acutatum occur?
Colletotrichum acutatum has been regarded as a pathogen of countless host plant species, and also as occurring everywhere. Sreenivasaprasad & Talhinhas ( 2005) discovered that C. acutatum group A5, here accepted as C. acutatum s. str., occurs only on certain hosts, mostly in the southern hemisphere.
What is the ex-type strain of Colletotrichum acutatum?
The ex-type strain was included in the study of Nirenberg et al. ( 2002) as C. acutatum, and one of the strains studied (CBS 120708) was included in a paper on Colletotrichum diseases of chilli in Thailand ( Than et al. 2008a ), in which ITS and TUB2 sequences were generated.
How to distinguish Colletotrichum phormii from other species?
We have confirmed this in our study. Colletotrichum phormii can be distinguished from the closely related C. salicis (and indeed from all other species in the C. acutatum complex) by its elongate, large conidia and large appressoria (Tables 2, 3 ).
