Carol Cloud Bailey: Don’t leave palm stump after removing the tree

.... Ganoderma will infest living and dead wood and is spread by spores. Spores are released from mature conks, which develop on living palms or stumps. Spread by wind and water, spores germinate in soil and grow on palm roots until palm wood is found to rot.

If you find a conk, remove it quickly, place in a bag and dispose of in the regular trash. Ganoderma cocks and infested wood can spread in mulch if the mulch is not subject to the heat of composting.

Be kind to your palms and remove any stumps to slow the spread of Ganoderma butt rot ...

Ganoderma Butt Rot of Palms

University of Florida IFAS Extension
Monica L. Elliott and Timothy K. Broschat: Ganoderma butt rot is a lethal disease of palms, both in the landscape and natural settings. While the disease is more prevalent in the southern half of the state, where palms are in greatest abundance, it is certainly not restricted to that area. The fungus that causes the disease is distributed throughout Florida, from Key West to Jacksonville to Pennsacola. It is also known to occur in Georgia and South Carolina ...

GANODERMA AND BUD ROT, OILPALM - MALAYSIA, COLOMBIA

International Society For Infectious Diseases
The East Malaysia Planters' Association (Empa) said a relatively new disease named Ganoderma is causing considerable damage to the palm oil industry in Sabah. Its Chairman, Othman Walat, said more than 35 percent of the palms could be killed by the disease. "Yield losses as high as 46 percent have been reported here," he said.

Othman said oil palm is an important crop to the country and in Sabah it still remains the top export earner. He said Ganoderma could seriously affect the revenue of the industry, Federal and State governments. "But in view of the fact that the disease is relatively new to East Malaysia, there is a need for more research and extension work," he said. One of the few proven methods for Ganoderma management is by sanitation measures during replanting. He said it is crucial to avoid cultural practices that will aggravate the situation ...

Ganoderma butt rot - fact sheet

Botanic Gardens Trust: Ganoderma Butt Rot is caused by Ganoderma applanatum (formerly Fomes applanatus). This fungus is an important decomposer of logs and stumps but it also colonises wounds, and can cause decay of sapwood and heartwood in roots, butts and trunks of trees. It affects native tree species such as acacias, eucalypts and beech, as well as many introduced species such as oaks, elms, ash and some conifers such as Douglas Fir...

Ganoderma applanatum produces very distinctive, shelf-like fruiting structures or brackets. They are most commonly found on stumps or near the base of living trees, often at the site of an old wound. The brackets of Ganoderma applanatum are some of the largest produced by any fungus. They are hard and woody and grow perennially for 5 to 10 years, reaching as much as 50 cm or more across and 10 cm thick ...

Gardening Q&A: Palm with ganoderma eventually will die

I have a paurotis palm approximately 12 years old and several of the stalks on one side of the palm are dying. I noticed a lot of ants in that corner of the palm and used ant poison, but the stalks are continuing to die. What could be the cause of it and should I cut all the stalks back to the ground or can it be treated? If it's beyond hope, let me know and I'll replace it. Removing it will not be fun...

Then, sometime in between the end of the day on June 10 and the start of the day on June 11, a tall palm near the rear of the parcel of land succumbed to the fungus called ganoderma but better known as butt rot. ...

Ganoderma Zonatum

Ganoderma zonatum is a white rot fungus that produces numerous enzymes that allow it to degrade (rot) woody tissue, primarily lignin and cellulose. As the fungus destroys the palm wood internally, the xylem (water-conducting tissue) will eventually be affected.

The primary symptom that may be observed is a wilting, mild to severe, of all leaves but the spear leaf. Other symptoms can best be described as a general decline – slower growth and off-color foliage. However, these symptoms alone should not be used for diagnosis of Ganoderma butt rot, since other disorders or diseases may also cause these symptoms.

Ganoderma butt rot is caused by the fungus Ganoderma zonatum. This fungus degrades or rots the lower 4-5 feet of the trunk. This has three implications. First, this means the fungus is not spread with pruning tools since the fungus is not associated with leaves. Second, this means that only the lower trunk portion should not be chipped and used for mulch. If possible, the diseased section should be placed in a landfill or incinerated. The remaining, fungus-free portion of the palm trunk could be chipped and used for mulch in the landscape.

Trees being felled for safety reasons in Falmouth public gardens

... It has been identified that the pine tree at Fox Rosehill Gardens is infected by a root decaying fungus, commonly known as Cauliflower Mushroom (Sparassis crispa).

This fungus affects the roots and ultimately the stability of the tree. A number of tests have been carried out on the tree which have shown that the infection is now at an advanced stage and felling is the only available option to maintain public safety.

The Turkey Oaks at Gyllyngdune Gardens have reached maturity. Some of these trees have recently died and others have been infected by bracket fungi, Ganoderma ...
