    There are organic sprays for PM that are supposedly safe to use on foods and stuff up to harvest day. They have them at normal hardware stores. I think sulfur based is common.

    As an alternative to eagle20 you can get immunox. Same active ingredient as immunox but cheaper and available at lowes. Make sure it is not immunox plus though. That also has a pesticide. I was thinking that could possibly be good for if you have mildew AND a pest problem but it actually might not be food rated never used it. It's my understanding this shit (regular immunox) oes knock out PM though. It is safe to spray on food stuff as well but i think u can only use it up to 30 days before harvest or something. The key to knocking it out is to use a systemic rather than a "contact" but I would probably only do it during veg all these chemicals are pretty Nasty but u gotta lay the smack down on PM or it can get out of hand.

    Hey dude, here's a few things that have worked for me in delaying the return of powder mold while not harming buds before harvest; 1. Spray with regular water around a ph of 8 with the best bottle sprayers you can get, put one in each hand and go to town about an hour after lights off, don't worry about the buds, they'll be fine, just make sure they are staked. Make sure that your temp is warm enough in the dark(i like 75-78) with fans going to dry the plants completely before light comes on. 2. Similar to the first but you can add an ounce of neem per gallon with a 1/4 teaspoon of dish soap(i like organic) for emulsification. The neem makes a temporary barrier that PM has trouble breaking through. I never use neem in the last 1.5 weeks, yet prior to this it has worked really well. 3. Going a step further with the neem mix and add 1 teaspoon of baking soda. I find that when I add the soda I get an extra few days of no pm. I am about to try to substitute 1 teaspoon of green cure(potassium bicarbonate) to see if there's a major difference as I've heard it's slightly gentler, but my mix works fine so far. 4. Mix high ph water with potassium bicarbonate club soda(not sodium bicarbonate). This has a slight bubbling effect on dense spots of pm which seems to wash it off a little better. You have to mix the club soda with regular water because it is a bitch to spray by itself unless perhaps you have a power sprayer or something.

    Key Notes; after a few days I see very slightly burnt hairs here and there but bud production is not noticeably reduced and leaves are fine, make sure to have a long enough drying time before the lights come back on(i like 8 hours) after spraying, have a nice even breeze everywhere in the room, temperature that never goes below 75(get an oil radiator for $40), eliminate shadowed areas of plants and bottom trim, sulfur burn occasionally and only 5 days or more after spraying but before week 6. Spraying with high ph water alone is the safest and will knock down pm for a week or more if you get the spray right close to the plant(just be prepared with extra stakes). I intend to use eagle20 and then let my girls veg longer before flowering, thus dissipating the chems greatly before harvest 1 time in hopes i can be rid of this forever. Clean ALL your shit!

    Good luck all:)

    Ive used both eagle 20 & bonide liquid copper,while both knocked the shit out of the mold i use the bonide on every grow as preventative measures,i now spray every grow at the half way mark durring bud stage & havent had a problem with pm or grey mold "bud rott" since.

    Ive treated buds in the last 2 weeks with the bonide copper soap & after it stomped the molds ass it left all the buds perfect & no taste issues.

    If your leaves have more than tiny amounts of mildew dont waste time fukin round with milk or peroxide, bust out the bonide or eagle & save yer buds,organic or not its decision time ,using milk or peroxide or other remdies & hoping for best results may just cost you half your harvest.

    totally agree with this post. I have 10 different products on my shelf that supposedly work on pm.
    ALL OF THEM only knock it down temporarily. Eagle 20 CURED my plants, they look like new plants after treatment and not one person I gave it to said anything about tasting it.
    the only other product worth a shit is PMWASH, you can use it the day of harvest and it's mostly water.

    yea well if the mildew is on your flowers you need to cut them off to keep the rest of the plant. unless you can do what they said above, use the eagle 20 to treat and see whats going on.. you definitely dont want that gross stuff in your smoke.
