HELP!!! I've got MOLD

[mcstagger]

so i have a white mold issue. i saw a little and then it blew up on me.
i clipped a lot of leaves but still have plenty cause i have huge OUTDOOR bushes. they are just starting to bud (some new pistols) and i want to clean the leaves vs cutting a ton more if it keeps up.

i have been 100% organic so far and would like to keep it that way.

what can i do?

White mold?

Do you mean white Powdery Mildew?

Mold is more like a rot with destruction of the tissue.

If it is PM then there aren many things you can do to help.

 

[mcstagger]

oops

yeah its PM

and some people recommend a lot of fungicides. but one person recommended HydroGuard to control dampening issues. he said it would kill the PM overnight and i like the sound of that but i want to no more about how it will affect the newly forming pistols and how long it will last in the plants system, i would definitely want it out by the harvest.

any comments on this product?

I tend to like sm-90 very much for pm! Has many uses and is a natural product.

For Treatment of Root Rot

SM-90 is a root disease inhibitor which controls common anaerobic fungal and bacterial pathogens. Effective treatment for root disease from ascomycetes pathogens including fusarium, pythium, rhizoctonia, phytopthera, sclerotinia, etc. When added in small quantities directly to plant nutrient solutions, root disease infestations are inhibited and new root growth emerges. Treated plants develop greater root area and root runs and exhibit a generally healthier root development.

Application rate: Apply 2-3 ml to each gallon of nutrient solution on a weekly basis or whenever solutions are replaced. Routine use will provide preventative treatment to keep problems from developing during all stages of growth.

For treatment of tissue fungus (stem and leaf)

When applied directly to foliage or stem SM-90 is an effective agent to treat for many molds, mildew and leaf spot, etc. Effective treatment for botrytis, blight, fusarium, leaf mold, rhizoctonia stem rot, sclerotinia stem rot and others. SM-90 is prepared from natural plant oils and is completely non toxic to humans, animals or of course plants. It is totally biodegradable and environmentally friendly.

Application rate: Dilute 1 part SM-90 with 5 parts water to prepare a concentrate spray. Apply directly to affected areas of plant leaves, stems. Treatments may be repeated twice weekly until infestation is eliminated.

For treatment of insect infestation

When applied directly to foliage or grow mediums SM-90 is an effective agent to discourage and eliminate many common pests including aphids, thrips, spider mite, and whitefly, etc. It is believed to act as a systemic to inhibit insect colonization and to deter reinfestation.

Application rate: Dilute 1 part SM-90 with 5 parts water to prepare a concentrate spray. Apply directly to affected areas of plant leaves, stems, or roots. Treatments may be repeated twice weekly until infestation is eliminated.


Additional Benefits

Controlled lab and greenhouse tests revealed an unexpected benefit that was observed with the treated subjects. Results indicate that SM-90 dramatically increases the transpiration rate which improves the plants water and nutrient uptake capability. The plants treated consistently used 30% more water and nutrients than the control plants. This would result an increased metabolism and accelerated growth rate.


Most plant diseases are encouraged by certain environmental conditions such as high or low temperatures, high humidity or poor air circulation. Over watering often contributes to the onset of such diseases. The effectiveness of SM-90 is dependant on the severity of the condition and the correction of these contributing circumstances. NOTE: The effectiveness of treatment on viruses is yet undetermined.

hmm, i think i found what i am looking for.

Do you know if this will discourage "leaf curl" ?





*ALSO* where do you buy these things? online or in a store. i feel shady going to a hydroponic dealer.

5:1 for a foliar and 3-5 ml/gal as a root zone treatment....good stuff, kills lots of pests as well as treating pm

For powdery mildew, spray both sides of the leaves with a couple teaspoons baking soda per gallon of water. Also it might be helpful to add a couple drops of dish detergent like ivory to help it spread on the leaf.

[mcstagger]

guys, i appreciate all the help. i found a retailer that carries SM-90 and i'm headed there tomorrow. would it be total overkill to use Hydroguard as well?

 

[HarryNugz]

let us know how it works for you. you can spray it on with different size sprayers. for small plants or precision spraying, i like the misty mate sprayers. for medium size to larger i like the quart size pump sprayer. For a larger garden, or large plants then a larger pesticide or fert sprayer will get the job done. Just don't use a used sprayer that had weed killer in it or DOH, you just killed the wrong weeds!!!!

mistymate , the medium sprayer, and larger sprayer can be had at wally world.
can also get a misty mate from their website.

The baking soda method works ok but it leaves white spots all over your leaves which resemble powdery mildew itself. Just go get one of the natural products out there like sm-90 or safer fungicide. Organicide works ok too. peace, jiggy.

I was using 'remedy' as a preventative (like baking soda, but potassium instead of sodium bicarb.) and I was seeing tiny white spots here and there and I thought it was from the spraying too.

Now, I see one huge streak on one leaf that's way out on it's own, right as you come in the door and it looks like PM, but I don't know as I've never had PM. I don't think it should be PM as there is a breeze constantly blowing over that one leaf at least, and I've been spraying with remedy once a week. (I'm now in week 4 of flower.)

How can you tell the difference between PM and the stuff you've sprayed on?

The PM is thicker usually than a stain. It stands up more. Looks kind of velvety in comparison.

^^^ hmmm ...... what I saw was up off the leaf a tad, but only looking at it thru a loupe - and it wasn't velvety - kind of granular/powdery - one thing though, there was absolutely no leaf damage at all - the pics I've seen show the pm eating into the leaf - is that right? (and I only see this on one leaf out of thousands!) I took a pic but it's too blurry and I've since thrown the leaf out.

I think it's not PM but keep an eye out obviously.

Streaks? No, usually fairly roundish spots break out first.
