beneficial fungus and bacteria : anyone try these?

[digitalgate]

Beneficial fungus. Have anyone here try these?
These fungus is beneficial to growth of plant. Most important, it is a bio
control as Fungicides . It will cloud out other harmful fungus present in the
plant. It is proven that roots grow better and plant
have bigger harvest due to the fungus. Please check the link below/
Having beneficial bacterial growing in your plant will prevent rotting due to
bacteria. As bacterial tend to dominate an environment and kill other bacteria
which are harmful to plant.

Bio control for mites- anyone tried these before?

This grow in the mites or any insect and kill them in the process.

I be getting a shipment of these . wonder about its effectiveness.

The use of beneficial fungi, bacteria and nematodes is becoming more popular in Florida.

The Department of agriculture encourages the use of beneficial nematodes here in Florida.

I use Worm Tea extensively, which is the liquid runoff of a worm bed decomposing food waste. It will have all the fungi and bacterial you listed since they exist everywhere in the world in substantial quantities.

I find the results excellent and prefer this method since it has a wider range than an individual bacteria or fungi.

wah , somebody endorsing use of fungus and bacteria.

It is interesting. I don't think there is any harm in trying them. I am sure you are aware that the process is very slow and somewhat inefficient.

But I think many on the list are bacteria and may need a 'soil'. I see some can thrive on 'rotting plant material'. I am usually concerned if I see 'anaerobic' bacteria used freely.

From the links I find many of the chemicals produced to counter the other 'pathogens' are allergens.

I hope Tobi can comment on the use of them on orchids.

If Cornell says so, I guess it should be OK to pursue. But I did not see anything specific about the use of them by hobbyists.

Good luck

I use so much Thiophanate Methyl in my greenhouse and other systemic fungicides, these good guys wouldn't have a chance of being around long.

My take on this is, yes there are beneficial microbes that would eradicate and impede
potential pathogens in plants, however Mother Nature has given us a phenomonal
balance in microbic organisms as long as a good immune sytem is maintained. In simple
terms, in humans and plants alike, providing good nutrition, keeping stress free (as much
as possible) and using good hygiene is the best way of keeping potiental pathogens
from taking over. This factor is even more difficult to maintain when you are dealing
with a large volume of different plants with different cultural environments. I applaud
people like Cynthia and Jerry for dealing with the ongoing threat of pathogens in
their vast growing areas.

Jerry - aside from the nematodes, if you can find out what other types of microorganisms they are using, I would be interested in what they were.

Vast? Not me. Short 8' X 12' GH, and grossly over crowded.

Cynthia,
Are you telling me that you have over 1,000 orchids in that growing space?
I am truly amazed!!

now you really know cynthia.

I do not think we can get the exact microorganism in worm tea and they probably vary. I have the chemical analysis of worm tea but microorganisms would require highly expensive lab equipment.

By the way there is negligible fertilizer in worm tea. 50 ppm nitrogen; 8 ppm phosphorus; and no phosphate, yet it can eliminate the need for fertilizer. There is enough to keep scientist busy for years.

Cynthia you are not crowed, I just put 1000 new overgrown Cattleya on an 10 foot bench (2 levels).

It helps to have very small pots, as in Jerry's over grown Catts=pot too small. I repot every year, and only leave room for one new growth.

I just buy (money??!!!) a big piece of land and grow 2000. he eh he

I haven't tried Trichoderma on orchids but I have used it on other plants with good results. As a soil fungus I don't know how effective it would be for treating fungal problems on leaves. Should be good for root rot etc. One concern I have (and this is the reason I don't use it on orchids) is the possibility of killing mychorrhizal fungi as well as the pathogens. Over 50% of what I grow are terrestrial of varying levels of fungal dependance so I prefer to keep the Trichoderma innoculated plants as far away from my orchid growing area a possible. For most epiphytes this is probably of no concern.

maybe I should not make fun remarks like my overgrown cats so lightly. I buy them that way at really low prices. Many re-pot directly into 4-6 inch pots from 2 inch pots. They even flower in the 2 inch pots.

I try to always point out what is done commercially out of necessity is not a recommendation for hobbyist care. If I lose 10% of these plants they were still bought at 1/3 the normal price, and their is no personal attachment to any specific plant.

I believe Cattleya do better with re-potting every year or at least every other year.

These plants will take me and my wife a month to re-pot.

A lot of individual decisions on the re-potting is necessary. Most roots are removed (this is an issue in another thread) the amount of root rot on a plant that is 14 inches high with 6 pseudo bulbs in a 2 inch pot is often 100% in the pot and all viable roots are air roots.

It does show how strong orchids are and what they can do to survive

Hello Yoda,

Remember me.

Pass a few over to me leeeeeh.
