What kind of microrganism would fight Ganoderma in the soil effectively?

Question

Oil palm disease such as basal stem rot, and upper stem rot are caused by Ganoderma. These are important diseases for oil palm in Malaysia.

Answer 1

Ganoderma mushrooms, for the sake of their survival, have developed natural substances to prevent microorganisms, such as bacteria and viruses, from attacking them.  Finding a microorganism to fight them in the soil would difficult.  The best solution to control basal and upper stem rot in oil palm is prevention, early detection. and use of fungicide.

Answer 2

Information from "Plant Pathology" by Agrios 3rd edition 1988 stated the following, and I'll paraphrase.

It is important that any work done on the trees as in trimming and maintenance be done in the dry part of the year. Any cutting, and especially wounding and damage done is what will cause the disease. The spores are all over the environment and they will get into the tree anyplace they can, and most will spores will be in their highest concentrations during the wet periods. Damage from animals, people especially workers, storms, fires, broken limbs, need to be minimized and though tree paint probably won't do a lot of good, if you can seal the wound or damage it should help some.

There is an antagonistic fungi that seems to help a lot and it is called Peniophora (Phlebia) gigantia. This is a decay that is found on conifer logs, trees that have cones and I kind of suspect that they won't be growing close to oil palms as they are cool climate trees. It is available, come to find out, but the data sheet link below says the stuff is fairly toxic. I guess I would not really want it thrown off on me with chain saw oil or breathing it in. The spores work against Ganoderma and I read that the spores are mixed into the chainsaw oil to limit disease when cutting. The spore producing growth on the conifers looks like a lichen.Trichoderma is another good antagonist to a lot of pathogenic fungi, and might even be commercially available for treating Pythium and damping off problems. It is available also, see below.

Prevention is the best but the materials for the problem are available. Make sure like I say to avoid damage in the wet periods and anytime you see the disease growing on a tree, try to get rid of it. It makes a lot of spores and they go everywhere, especially when wet. Haul it and burn it.
