Go ORGANIC.

do you want cancer. throw them all away. they are only worth a few dollars. It will cost you thousands if you get cancer.

There are plenty of ways to get rid of the powdery mildew without poisons. Stop listening to stupid people in stores. they know nothing.

All fungus can be controlled without poisons.

Fungicides are the worst of poisons for people. Super very dangerous.

THROW IT ALL AWAY IMMEDIATELY. DO NOT PLAY GAMES.

You already played a game and lost.

GO ORGANIC.

there is an organic thread on Garden Web.

if you do a google search on organic gardening you will find other places that discuss methods.

Serenade for one is very organic and eats up the fungus like powery mildew. baking soda in water works as does an aspirin in a gallon of water. etc. others out there. some of these change the ph on the leaf so the PM does not grow. PM = Powery Mildew.

Good luck do not die from cancer it is a terrible way to die.

I am confused, the garden centers usually push Ortho Disease Control, which is a Daconil formulation. Bayer has a lot of Tebuconazole formulations (Elite®, Falcon®, Folicur®, Horizon®, Matador®, Milrod®, Nativo®, OnlyOne®, Prosaro®, Pronto®Plus, Silvacur®)which are registered for food crops including fruits and vegetables. In fact it is used on most commercial table grapes and stone fruits. It is mildly toxic ( LD50 3000mg/kg). no carcenogenic or mutagenic properties found. On the other hand, baking soda does work fine on powdery mildew. and the product you obtained may not be an approved formulation or contain other products which render it unacceptable for food products. It ALWAYS pays to read labels thoroughly and use a product only for its intended uses. And that includes "Organic" products some of which are really bad actors when abused.

Elizabeth,

Well, while it's great that you weren't afraid to ask the workers, I think you learned it's best to read the label first before application no matter what.

In the future, you can always ask at this forum what you can do if you have an issue before going to the store.

There are usually very good homemade organic treatments you can mix with things you probably already have. The best fungicide treatments usually involve baking soda.

It is odd that the company can/will not give you a straight answer. I suggest you call your county extension service and ask for the number of a plant pathologist. If they can not give you one, you can easily find one online in order to ask them.

Only you know how much you sprayed and on what. If you're worried, trust your instincts and consider it a learning experience. You won't make the same mistake again. And always know that there are far safer ways of attempting to control a problem than purchasing a commercial, chemical product.

Here is a link that might be useful: Use of Baking Soda as a Fungicide

I agree with the others on the absolute necessity of reading the labels of *any* garden product organic or not, but won't beat you to death with the "READ THE LABEL" thing as I suspect you have learned your lesson the way I and many others did - the hard way ;-)

Baking soda is a superb fungicide and you don't have to worry about labels or waiting periods before you may (supposedly) eat the plants safely.

1 rounded tablespoon of baking soda to 1 gallon of water. Very simple and in my experience very effective against powdery mildew.

Another 'recipe' is to substitute milk (any homogenized milk will do) for 10-50% of the water. Milk is also a fungicide and has been tested under controlled conditions to be highly effective against PM on grapes, but really hasn't been very effective for me in my gardens. Still, whatever benefit it can offer will be more than the water by itself does ;-)

Did they specifically recommend the Bayer product? One of the most effective products I use on giant pumpkins (a big winter squash) is Ortho Garden Disease Control. Is there a chance they were thinking of this, or maybe they told you to use this but you got the Bayer product by mistake? Just curious.

And NO, it doesn't cause cancer and most veggies can be harvested the same day as applied.

Please explain how to use the baking soda and/or aspirin treatment for powdery mildew. I'm assuming just mix up the solution and spray on the leaves?

What works on the fuzzy black mold that grows on the blossoms and fruit?

correct. Cover leaves topside and underside until dripping.

The name of the product is "Bayer Advanced Disease Control for Roses, Flowers and Shrubs". That is the name of the product in big letters on the front of the bottle. That should tell you something right there. It says right on the label "Do not apply to plants grown for food".

This has nothing to do with being organic or not going organic, it is about reading and following label directions.

Last week I sprayed a cornmeal juice and dry milk solution that was previously mixed in a gallon of water. My tomatoes and cukes were on strike 3 and about to be pulled. Went out today and noticed new growth and now some new tomatoes. I'm sold on this solution as a fungicide.

The Ortho Garden disease Control is daconil - OK to use on veggies. Was out this morning spraying it on my tomato plants to control early blight.
The Bayer product should NEVER be used on edibles. Sorry, but you ought to discard the plants you sprayed with it. Idminacloprid is not the most poisonous material around (it's an ingredient in the tick control applied to dogs) but it is systemic - gets absorbed by the plant and its fruit.
I've tried baking soda - unfortunately it doesn't work as well as daconil.
