I know prevention is the best plan of action for powdery mildew, but I have read on some posts that some growers actualy ''cured'' there powdery mildew on their plants before,,, cured? really?,, I know you can control it to a certain point but ''curing'' it, I have never had that luck before or have I seen pictures of a leaf with powdery mildew then that same leaf being cured.

Whats the best product out there that you guys like to use when you start seeing powdery mildew? I heard Milk is a great alternative, but what has been most effective for you once you start seeing it on the leaves?

i haven't tried it, but i just did some research on a syngenta product called "quilt". i saw it meat57s diary (tyson naylor) that he is using the product. from what i have read it is a preventative and an eradictor in one. i am not sure where to purchase it though. i too am interested in more powdery mildew cures for the future. cuz what i have read is that powdery mildew can lead to early fruit maturation due to a huge increase in "senesence" i know the spelling is wrong, but it is the maturation chemical the plant produces for ripening. that is not what i like to here, cuz i hope for long term growth.

BrookZ.....We use one TBL of Baking Soda, 3-4 OZ 2% milk, 1/2 oz Spray Tech Oil added to our daily spray of either CA, 0-13-0, etc....every night now.....One can spray just the PM Preventor earlier in the day....It has smothered PM that has started. I have tested it on bind weed too and it takes out their type of PM. Give it a shot....

Next I am trying Cracked corn meal Foliar spray that Ross sent me...but am a bit concerned about my other Good Fungus growing too, Hope this helps...Give it a try....works for us.

i just purchased some jms stylet oil as an eradictor and talked with the rep. 2 minutes ago. wait 7 days after using daconil when hitting with stylet oil, and agitate every 10 minutes at a rate of 3 tablespoons per gallon of water when applying. it is compatible with most other fungicides and actually helps systemics work better in the process. this will be my first time trying it in 5 days as i just applied daconil heavy 2 nights ago. it is supposed to kill on contact by disrupting the cell walls and the loosening the attaching mechanisms of the pm spores to the leaves.
3 kinds of systemics in rotation didn't work all that well here this year as the cool temps let it set up by late july.

Wiz-what is spray tech oil? Is that a brand or type of oil like light horticultural oil? Where do you get it?

Get yourself some horticultural corn meal, go generic if that be your choice, put a few cups in an old nylon stocking or sock and dunk it vigorously in a 5-gal pail of water. The water turns milky-white. After sufficient dunking pour that water into your pump-up sprayer and apply to all leaf surfaces and stems. Over-spray upon the soil only helps to feed and nourish the microbes in the soil. One big happy family.

Consider putting this same cracked corn meal into your soil next year where you are planting 'kins, squashes, zuchs, or anything (susceptible to PM). Feed the microbes. Build up a high population of the Trichaderma (good) fungi in the soil and let the good fungi do battle with the bad guys. Soil microbiology is where the truest measure of growing successes are manifested. (Not with chemical use)

Spray such corn-water on a regular schedule through the season. You can not over-do it, not really. Add a splash of good vermi-compost tea as well, and a tablespoon per gallon of molasses. Thus, increased opportunity to prevent PM, rather than respond to treat such symptoms once those bad fungal colonies are large enough that one can see their presence, i.e. too late, the PM is now visible.

My 'kins, zuchs, squash and cukes are all robustly upright, full green, no powdery mildew,.....and no chemicals have been hastily of heavily applied. I know, I know, one does not really eat giant pumpkins, so the use of chemicals with long, multi-syllabic names is often the products of choice.

And, we have probably had the rainiets, wettest, coolest May, June and July in CO in several decades.

Quilt is made of two components Quadris systemic and Tilt curative. My syngenta rep said these products are excellant for pm but we have been using them for diseasee control in corn, soybeans, and wheat for years. I alternate quadris and quilt every other spraying and pm is basically non existant. If pm shows up I spray the infected area heavily with Quilt and the pm turns from white to a very dull gray color almost to where it is hard to see on the leaf and does not continue to spread.

We alternated: eagle, daconil, dithane. worked well for us,,after first signs in early july it did not spread, or very very slow.

Great post, thanks for all the replies so far, I already have a few ideas from this post Im going to try now.

Tomato man, thanks for re-posting that, I forgot all about when you posted that about a month or so ago,,, I said to myself I was definitely going to try your idea when the time was right this year but it completely slipped my mind. Sure glad you re-posted that to remind me to give it a try.

Tomato man,,,Question on the cracked corn, I have feed corn that isn't cracked that I get from a buddy farmer of mine that I use for my deer feeder. Now this would be about the same right?,, only thing it isn't mashed (cracked), right? Could I use this feed corn and soak it like you explained, and would it still work the same? I know I would have to let it soak a day or two for the corn to get soft but would this work?

Thanks again everyone for your input, I never stop learning on this site.

We use it from the Agro K program and it has worked for us on the PM. Going to try the Cracked corn soon as I see some....PM.....YO

Brooks a product called M-pede ( formally safe soap) is great for PM. It dries up the PM spores on the leaves. So I tank mix it with my other fungicides to dry up PM & to keep preventing it as well.
I have some extra I could spare for you if you want. Your not to far away, we could figure something out.

could someone tell me about Immunox Plus..active ingredients include .78% myclobutanil and 1.25% permethrin, am i on the right path for PM?
thanks

Straight Immunox is better in the heat. "Plus" contains permethrin insecticide.

Less is more sometimes.

If I remember correctly think Tremor said that the myclobutanil in Immunox is the same active ingredient as Eagle, which is a systemic. The Permethrin in it is a contact insecticide. Hopefully he will chime in here.

I rotate Dithane and Pristine with great results. It doesn't make the mildew you already have go away but it does a good job preventing it from spreading.

Brooks,....One needs to get the most of the material inside the kernel. Your friend's whole kernel stuff for the deers, soaked in water, is not likely to get the by-product you want in any short period of time. The processed corn bread mix from grocery store is also not what you want.

Put "Soil Mender Products, Horticultural Corn Meal" into a Google search and start reading.

I just did that.....and 7 hits down the list is THIS Big Pumpkin chat forum posting !

Use corn meal instead of cracked corn. Corn has to be made into a meal in order for it to work. Go to your local feed mill and buy it.
