Yea, it struck my English Peas.  I don't think it is much earlier than normal.  It always strike these particular peas just as they are maturing.  I tried a concoction of Baking soda and water to try to kill it.  It worked on some of the peas but on the worst ones it did not work.  I made it a little too strong and it left brown spots on a lot of the leaves but the brown spots are better than the powdery mildew.  I cut down one group of peas today (almost completely harvested) that were the worst.  The first one that I snipped raised a cloud of white powdery stuff.  So I then wet all the pea plants that I was cutting down to keep from the white powdery stuff blowing all over the garden.

Has anyone tried a non-fat milk solution for PM? I have used it with success when the PM is just starting.

My experience with most of the solutions is they delay if the weather cooperates. Ill give it a try though .Whats the non fat milk mix?

I would also like to know.  I went to the store and purchased non-fat milk then came home and looked on the internet for the exact ingredients.  One recipe said 1 part milk to 9 parts water.  Another said 1 part milk to 1 part water.  That is why I used the baking soda recipe.

I started with 1:9 (10%). Then I changed to 1:1 (50%). Probably will try 1:3 (25%) this year.

from dirt doctor when I had powedery mildew on my comfrey ealier this spring.
Spray the 50/50 hydrogen peroxide and water or mix the peroxide into your Garret Juice spray. 


from his website:
Crape Myrtle Powdery Mildew
Powdery mildew attacks crepe myrtles and other plants especially during humid weather. The control is to apply horticultural cornmeal to the root zone at 2 lbs. per 100 sq ft and spray the foliage with Garrett Juice plus either potassium bicarbonate or cornmeal juice. Cornmeal juice is made by soaking a pound of cornmeal in 5 gallons of water. Put the cornmeal in a nylon bag made from old panty hose or whatever to keep the larger particles from getting in the water. This cornmeal juice can be used alone or mixed with compost tea or Garrett Juice.  
 
Potassium bicarbonate Fungicide

Mix 4 teaspoons (about 1 rounded tablespoon) of potassium bicarbonate into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases.  Potassium bicarbonate is a good substitute for baking soda. There are commercial EPA registered as well as generic products available.

Baking Soda Fungicide
Mix 4 teaspoons (about 1 rounded tablespoon) of baking soda and 1 tablespoon of horticultural oil into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases. Avoid over-using or pouring on the soil. Potassium bicarbonate is a good substitute for baking soda. Citrus oil and molasses can be used instead of horticultural oil.

I use powdered milk, but I don't measure it, just dump some in with the water until it looks like watery milk.

That’s a great idea...so much cheaper.

WARNING - Reaction to Powdery Mildew sends me to the ER.

I was out today (Sunday) pulling my pea vines that were covered in powdery mildew.  While I was pulling the vines out, I noticed a soreness in one eye.  About 2 hours later my left eye no longer had any white showing.  It was blood red.  I panicked a little and went to the ER because I have a heart condition and have had a stroke previously.  I did not know if the red was a result of burst blood vessels. 

The doctor said I had some reaction to the powdery mildew.  Could have been an allergic reaction or bacterial.  While I was pulling the vines, the weather was hot and humid and I was sweating.  I must have rubbed my eye with powdery mildew all over my hand.  He said next time to wear gloves.  I just might also wear goggles to keep me from rubbing my eyes with a powdery mildew covered glove.

How scary! Thanks so much for the alert - I am allergic to pretty much everything, will be sure to heed your warning.

I hope you're doing better. How did the doctor treat it? Any drops or ointment or anything?

The ER Doctor gave me eye drops and a prescription for more eye drops.  The white of the eye was 100% red last night and now it is about 75% red so the medicine is helping.  I am supposed to make an appt with an ophthalmologist for tomorrow to check it out.  He kept using the term allergent but the paperwork says bacterial conjunctivitis.  "Acute conjunctivitis of left eye, unspecified acute conjunctivitis type".   My prescriptions were acetaminophen-codeine (I am just using regular Tylenol) and Gentamicin (Garamycin).

Went to the ophthalmologist this morning.  Nope, it was just a burst blood vessel.  I asked him why it burst.  He said they do not know but it had nothing to do with the powdery mildew or my blood thinners.  Stop using the eye drops the ER doctor prescribed and just wait about 10 days and it will be all cleared up.

That's good news. Avoiding powdery mildew for the rest of your life could have been a real challenge.

First, I'm glad that your eye will be OK and that it wasn't an allergic reaction.  Second, thank you for sharing your experience.  I'm kind of a newbie and didn't realize it was powdery mildew on my English peas.  I have asthma so, after reading about your experience, I'll know to wet the leaves before pulling the plants.  Hope you recover quickly!
