Remedies for PM

    Good morning,

    So ... while I was at my local nursey to pickup supplies over this past weekend the owner asked how my grow was going? I replied Great!!! with the exception of a small Powdery Mildew issue that I just can't seem to shake.

    It took me upto 4 years to completely rid my grow of those dreaded "Spider Mites", most of that time spent was somewhat learning to live with them as other fellow grower friends said i'd have to do.. While I disagreed and tried many things to get rid of them many products only seemed to devastate the plants rather then the invader.

    Water - plain old unconditioned water was what worked in the end. Who knew, the almighty mite couldn't build a resistance to water under pressure. I won that long winded battle and have been completely bug free for the past 6 months. Thank God and Knock on wood there gone.

    Now, life in the grow op has turned to another criminal suspect of any growing enviroment and sadly this scenario comes with as many recipes for riddance as the ones for Spider mites. This one is Powdery Mildew.

    I believe it began during the high humidity runs caused by the every 3 day rinses under the shower massager during the spray treatments getting rid of the mites. Lots of water logged plants dripping there way to dryness before returning to the lights.

    So, while at the nursery fetching the months supplies and chatting with an old friend (the shop owner) about the adventures of growing and trying to dial my grow back in - we touch base on the PM issue which of course he had a remedy he thought he'd share. I'm questioning the use of H2O2 or Hydrogen Peroxide in the mix and thought i'd post it here to see what you all think.

    I read elsewhere (on another forum, sorry guys) that a grower used high pH (8.4) adjusted water to eliminate the problem entirely in his grow. Of course that saying "Your milage will vary" comes to mind. This was a method I was going to try because I just hate spraying unwanted things chemical or otherwise on any of my plants. Bad things have happened in the past.

    So, this recipe calls for:

    2 cups water
    2 Tablespoons sugar
    1/2 oz h2o2

    mix together and spray liberally on infected plants.
    I question the H2o2 being its a pretty strong product even though it'd be diluted in the 2 cups of h2o.

    Would any of you use this recipe or do you spend the $$ on other made products that say they work but, really don't and only leave you learning to live with it by controlling the situation rather than eliminating it?

    Thanks for your time and have a Great day

    i battled powdery mildew for 4 years. using various methods, before using the "nuke" option (eagle 20). i have tried them all. plain ph 7 water, didnt work. safer products "fungicide", didnt work. and a number of other organic and non organic solutions that didn't work, or worked for only a short time, then the powdery mildew came right back. that is until i tried eagle 20. i was supposed to only use 2 applications of eagle20 spaced a week apart. i only did one. 4years of powdery mildew war won in a single battle. i used it 2 years ago. i havent seen powdery mildew since. i am pretty sure i brought the powdery mildew inside, from an outdoor crop, and it had nothing to do with my indoor environment. i know this because i did not have powdery mildew before bringing the outdoor crop inside to dry, and have grown in the same location for over 14 years. the years prior to the powdery mildew outbreak were PM free. for roughly 4 years i had it. i sprayed them ONCE with eagle 20, and none of the plants that were sprayed were deep into flowering, so i was in a good time frame to spray anything, since there was still time for the chemicals to dissipate. im pretty sure the chemicals that were sprayed on the plants 2 years ago, is gone. the mother plants that i originally had are also gone, so there is no chance of any residual chemicals lingering. im not sure why people are so afraid to use some chemicals, if you are smart with application, and reading directions, and some patience, there arent any negative results. i have not had powdery mildew since or seen it on any of my indoor plants.

    regarding your question, of the use of H2O2 in the recipe given, im going to say it depends on the strain. why not make a small batch and "test" the recipe on a few leaves or small section of plant, before attempting to use on a larger set or on a bunch of plants? be sure to wait a few days to a week, to see the plants reaction.

    Good morning,

    Thanks for the reply Bob, I found the Eagle 20 at amazon, I think i'll be ordering a bottle cause like another thread I started titled, "I'm just so tired", which pretty much says it all in a nutshell. I'm just so tired of dealing with the bad things that happen in a grow op in the wake of other bad things that have happened.

    Wheres the light at the end of the tunnel - have I missed when my eyes were closed after that last hit or have I not arrived at the spot to see the light at the end of it yet. Questions n queries asked, a few answers echo back.

    Anyway, thanks for the reply, i'm sure i'll let others know when I have eliminated this issue from the grow. I just can't wait til i'm back to that other "W" word, "Watching" the plants grow healthy instead of "Wishing" they'd be that way.

    Have a Great day
