Trichoderma (& treatment of Botrytis galanthina)

[Lesley Cox]

You might be able to wet the powder and water it on, say onto planted out Galanthus.

Of the affected clematis early on, they died and that was that, and since using the Trichoderma none has been affected so not as a treatment as there's been nothing to treat. Having said that, since so many died BEFORE the Trichoderma and since I still use the same source (there was only the one specialist source in NZ for a long time, a couple more now) it's reasonable to suppose that new plants or some of them had the wilt fungus present, and it hasn't appeared, so if it was there, presumably it has been treated by the application of the granules into the planting hole. The silverleaf thing suggests that it is a treatment as well as a preventative.

I tried to place an order with this company http://www.growell.co.uk/p/0972/Trichoderma-Powder-Tri-003.html

No way no how. One has to register to pay by credit card and it won't let me register because I don't have a postcode. I usually just enter a few 00 and it works but not this time.

What sort or genius sets up these web sites.?

Lesley it's very interesting you are telling about Trichoderma. Here we have Trichoderma lignorum in granules. I've always thought it is something like placebo and never used it. I also have some wilt problems on clematis. And certainly I'll try Trichoderma on them next season.

[Michael J Campbell]

Thanks Chas.

[Lesley Cox]

Olga, I use it on many different things now, especially anything tiny I want to establish quickly in our (usually) hot summer. I don't yet sprinkle it on my breakfast cereal but maybe it won't be long.

Just in case anyone wondered, I DON'T have any financial interest in the products.

Lesley,
I tried to identify a supplier of Trichoderma and browsed Czech web pages.
The results are surprising for me. It is known solely to illegal growers of
marihuana who use it in the pot culture of Cannabis plants.
Therefore the price is astronomic, as stated above.
You should write a detailed essay on its benefits in rock gardening in
a serious European journal in order to get it in normal distribution.

Trichoderma .... is known solely to illegal growers of
marihuana who use it in the pot culture of Cannabis plants.

Aha.  I wondered why it was only on sale here from hydroponics specialists!

[Lesley Cox]

Maybe Google NZ pages. There's a lot about how it is manufactured, uses and the assorted research done. I have a private email from a Forumist which I'll answer in a few minutes but will say the same thing here as to him, it needs to be used only once. I use granules when I pot anything at all tricky or anything which is prone to fungus attach and that once is all it needs. There's no need for an annual top up. For the same reason I think it would be worthwhile to recycle any mixture from old pots where it has been used as the fungus is still there and active, and would be beneficial in, say one's vegetable garden or recycled onto a woodland bed.

I sometimes still use the water on version but mostly not nowadays with nursery plants unless, again, they are something on the tricky side. The reason for this is that after the watering, plants in 90mm plastic pots grew so well and so quickly that they needed repotting within 3 months whereas they were actually stock for the full year ahead.

I use a similar product of 'friendly' fungus named Rootgrow
just bought it a few weeks ago and used it on newly planted/divided snowdrops
I`m gonna use it with all the planting this spring

[Lesley Cox]

Loes, if you read the fine print on the packet you will very likely find the active ingredient is Trichoderma fungus. It is available here in various Brand names, including Rootmate and Plantmate.

Hi,

At the risk of boring everyone with science. Here are two abstracts of studies into the use of two different species of trichoderma in inhibiting Fusarium oxysporum in commercial onion crops.

It would appear that it has significant efficacy. I guess the question is: Are their limiting factors, i.e. soil temperature, re-inocculations, colonization pre-requisites, etc.

Postscript: The second study looked at white onion rot (sclerotinium). It would appear disease supression can also result from the production of anti-fungal compounds.

Marcus, as I know it works under 20C.
