Classification of anthracnose fungi
What is the scientific name of anthracnose?
Glomerella cingulata (anthracnose)
What type of disease is anthracnose?
Anthracnose is a term used to loosely describe a group of related fungal diseases that typically cause dark lesions on leaves. In severe cases it may also cause sunken lesions and cankers on twigs and stems.
Which fungi causes anthracnose?
Anthracnose is caused by the fungus Colletotrichum lindemuthianum (Sacc. & Magn.)
What is meant by anthracnose?
anthracnose, a group of fungal diseases that affect a variety of plants in warm, humid areas. Shade trees such as sycamore, ash, oak, and maple are especially susceptible, though the disease is found in a number of plants, including grasses and annuals. anthracnose.
What causes anthracnose in plants?
Anthracnose is especially known for the damage that it can cause to trees. 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.
What is the life cycle of anthracnose?
Disease Cycle: Most anthracnose fungi infect their hosts during the spring, just as the first new leaves begin to expand; infections continue through the summer while environmental conditions are suitable. Spores are released from last year’s diseased tissue (most commonly from fallen leaves).
What plants are affected by anthracnose?
Potted plants and greenhouse crops such as cyclamen, ficus, lupine, palms, succulents, and yuccas are sometimes affected. Trees and shrubs that are prone to anthracnose include maple, camellia, walnut, ash, azalea, oak, and sycamore.
What trees are affected by anthracnose?
These diseases are common on ash (Fraxinus), maple (Acer), oak (Quercus), and sycamore (Platanus). Anthracnose is most noticeable on trees in the landscape, but disease also occurs on trees growing in natural woodlots and forests.
What are the diseases caused by bacteria in plants?
Control
| Some bacterial diseases of plants | ||
|---|---|---|
| disease | causative agent | hosts |
| Granville wilt | Pseudomonas solanacearum | tobacco, tomato, potato, eggplant, pepper, and other plants |
| fire blight | Erwinia amylovora | apple and pear |
| wildfire of tobacco | Pseudomonas syringae | tobacco |
How is anthracnose transmitted?
Anthracnose Tip: Plan your gardening tasks, including harvests, for times when plants are dry. Anthracnose can spread from plant to plant via wet hands, pruners, and clothing.
What is bacterial wilt disease?
Bacterial wilt is caused by a soil-borne bacterium named Ralstonia solanacearum (formerly known as Pseudomonas solanacearum). Potato wilt bacterium mainly inhabits the roots, and enters the root system at points of injury caused by farm tools or equipment and soil pests.
What is the mode of transmission of anthracnose?
The diseases are favoured by wet, humid, warm conditions. They are spread by infected seed, rain splash and moist wind.
What is the life cycle of anthracnose?
Disease Cycle: Most anthracnose fungi infect their hosts during the spring, just as the first new leaves begin to expand; infections continue through the summer while environmental conditions are suitable. Spores are released from last year’s diseased tissue (most commonly from fallen leaves).
Can anthracnose infect humans?
Colletotrichum species are common pathogens for plant anthracnose but have recently emerged as a human opportunistic pathogen causing keratitis and subcutaneous fungal infection, which potentially can lead to life-threatening systemic dissemination.
Can anthracnose affect humans?
In most cases, the answer is no. The fungi, bacteria, viruses, and nematodes that cause disease in plants are very different from those that cause disease in humans and other animals.
How can anthracnose be prevented?
This way the anthracnose spores won’t have a place to overwinter. Remove any infected twigs and cankers and disinfect any tools with a 10 percent bleach solution (one-part bleach to nine parts water) between making the cuts to prevent the fungus from spreading onto the same tree, or onto other trees.
When do anthracnose appear?
Anthracnose can occur during periods of cool temperatures in early spring and warm, humid weather in summer. Optimum temperatures for growth of the pathogen are between 70 and 82°F, but the disease often occurs when soil and air temperatures are significantly lower or higher than this range.
