This is new to me ... using Trichoderma as a pathogen to treat pathogenic root fungi.
Found this page http:///bugs.bio.usyd.edu.au/Mycolog...athogens.shtml
Otherwise everything else I found related to damping-off type fungi, in nursery environments.
Is this a normal practice up northern NSW and/or Qld. and what is this adjunct better known as...
Is it a cost effective option to use as a preventative measure.

If you go hang out at the farmers type chemical stores you'll be very surprised what you find.

But in saying that there's horses for courses, the most likely fungi to invade trees up here would be Phelinus noxious, Ganoderma, Armillaria, Phytophthora & Anthracnose.

Some PDF docs I loaded up worth a read.

Havent read those attachments yet...
This post is because I visited the APVMA site to check label registration for Vinevax...It doesnt seem to cover anything but grapes/grapevines...AND there is no permit for special uses.
So maybe we should'nt recommend this product by name for use on woody trees as a purely preventative caution...transplants... yes
The latest Gazetted items are .... I'll keep a check for any updates.

Key part is this.

Quote:

Propose that products containing Trichoderma spp. that are represented, supplied or used for improvement of soil structure, improving survival of transplants, increasing beneficial microbes or microbial activity in soils, or digesting cellulose be declared as not being agricultural chemical products under Schedule 3 of the Regulations. Given the time this may take, the APVMA has granted a temporary exemption for the purposes of sections 75(1)(b) and 78(1)(b) of the Agvet Codes. This exemption means that it would not be an offence to possess such products for the purposes of supply or to supply them for this purpose.

Nice find.

And there's not a whole lot you can do about it, I dont think Trichoderma helps for those fungi.

Mango trees get anthracnose on the foliage tips.

What if it gets established in the soil and competes with and displaces the rotters?

There's a fair bit of anecdotal evidence for the positive impacts of foliar applications of suitably (after microscope leaf analysis) selected, properly brewed (aerobic) compost teas, in the battle with anthracnose and leaf blight. No substantive scientific studies though, I'd certainly be offering foliar sprays as an option to clients with those troubles.

The fungi I'm most concerned about is the ones I mentioned.

Quote:

Phelinus noxious, Ganoderma, Armillaria, Phytophthora & Anthracnose.

Phytophthora is best held at bay with Ausphos600, Trichoderma doesn't have much affect on the others above. The above (other than Anthracnose) are the prime killers here, the Anthracnose I deal with is mainly foliar on stressed mango trees ... not rotting the roots/stem away.

I dont like to use any chemical fungal treatment as a wholesale soil drench and would rather work on getting the soil right like Sean always advocates.

Here's a look at some research.

How to apply it?

Interesting to read this from page 13

Quote:

The additivion of glucose and urea
caused faster colonization of the wood samples by Trichoderma spp. and in their presence the
protective effect was increased (Hjeljord et al. 2001). In dual culture tests as well as in
interaction tests, significant differences between the species and strains of Trichoderma spp.
were evident. Thus, T-15603.1, T-351.93 and T-126.65 showed a high antagonistic potential.
By contrast, the antagonistic potential of T-396.92, the commercial product Binab and
especially, T-338.93 was limited (Schubert et al. 2008).
