    fungi typically do not do (technical word) photosynthesis and are found where there is little to no light but there are all different types of fungi

    so the answer is "maybe" depending on the strain

    Thanks...

    I was thinking specifically about some of the lawn diseases that have the mycelium/hyphae above the soil such as 'red thread'...

    Yeah pythium comes to mind too and then there are the fruiting bodies of fungi what we call mushrooms

    Bill,

    So you are saying - reading between the lines here and drawing my own -
    With the chitian in the NPP, and with the tea you have all known organic bases covered in relation - specifically to brown patch/spot with - chitian, bacillas subtillas and trichoderma?
    Pretty broad line I have drawn here but of the known anti fungal products out there you have three of them in two different products which is pretty cool - please send me my $5 for this post - LOL but seriously this is pretty cool.

    Does Chitian, bacillus subtillus or trichoderma harm the mycorrhizae?

    Mr Barefoot,
    chitin pronounced /ˈkaɪtɨn/ is the solid form
    Chitosan ˈkaɪtɵsæn' is the liquid form
    actually the "a" is pretty silent it is pronounced more like Kitin and Kiteosan

    to answer your question, you would have to ask the mycorrhizae
    what I have seen in peer reviewed papers is that they all work together. There is very good evidence that the bacteria and fungi work as symbiotic teams

    what did I tell you at the 2007 GIE show or was it the 2008 it's late, you would circle this route and realize we have done all of the research for you

    It's been mentioned on here before that the NPP(chitosan) is not easy on the biology. It may be the material used to make the chitin into chitosan. I think the pH on the stuff is in the low 3's, so maybe Bill can correct if I'm wrong.

    I've used the NPP and it works very well on typical cool season lawn diseases.

    Are you saying that T. harzianum, for exa., can take down shrooms?
    or was you onto another subject, with that post?

    actually with continued use you are selecting (by feeding) for microbes that like to eat it, these are typically chitonase enzyme producers that are beneficial in reducing fungal disease

    The pH is around 4 but it is diluted 64:1 or 128:1, we now send a 2 ounce bottle of REDUCE with the NPP, it is to condition the water and is meant to reduce the pH of the tank water to 5.5 to 6. we were having mixed results in higher pH water and have come to find that NPP works best in the range mentioned. "Reduce" has a pH of 2 and is a ferment (much like making beer) of organic acids
