I am considering incorporating mycorrhizal in my program next season. It seems pretty expensive. I have a couple of questions that I'd liked answered before I fork out the hard earned $$. First, has it been proven to actually work in any field studies? Second and maybe most importantly, what kind of fungicide program do you use in conjunction with the mycorrhizal program? It would seem to me that the fungicides we generally use would kill off the good mycorrhizal fungi. I'm no agronomist,and I sure would like to hear from Tremor and any other experienced growers on this subject.

ron wallace used it on his 1502 and Im sure still is, joel holland uses it and likes it, give him a call, he is where i get mine from.

milford, CT,

I have used Holland's Mycorizhae of 2 years and have increased my PB by at least 200 lbs a year. I Believe it does make a difference. It makes a whole lot of sense to increase surface area and soluability of nutrients by roots to uptake nutrients. I did an experiment with Myco vs Non Myco and the root development was amazingly different without. Mark

Technical article on the effect of fungicides on mycorrhiza:

Of the fungicides which are toxic to mycorrhiza you may still use them but apply just enought to avoid drips. The use of advanced organosilicone surfactants will help spread the fungicide out on the leaves without dripping it onto the soil (if you're careful!).

Tremor have you heard if chloramine {not chlorine}, a chemical water disinfectant that a lot of cities will be going with will kill off the mycorrhiza? thanks Kathy

Thanks everyone for your replies. Tremor - you the man! You do a lot for the growers here for little in return.

Just wait until you see what we're REALLY working on...LOL

No Kathy, it shouldn't be a problem at the levels used. Chlorine & Chloramine cannot persist in the overwhelmingly organic & biological environment presented. Mycorrhiza lives deep enough within the soil so that it's insulated against all but a flood of chlorine.

Remember that mycorrhizal inoculant must be physically placed in contact with the roots to work so it should never make direct contact with chlorine. Once chlorine is "filtered" through the biological soil it should be gone.
