[The empressof all]

Before I go pouring through the books I thought I would see if anyone here knows what is wrong with my Zucchini.

I woke up this morning and found what looked to be white spray paint on the leaves. I was able to scrape it off with my nail. It seemed to be a hard dust. I have a few blotchy leaves so I went ahead and just pulled them off.

It has been dry here so I don't think it's mold.

Any ideas

1. I think that is is a fungus

I live in Western Washington too, and that has happened to me.

I don't think it's related to heat or humidity. Yes, it's been very hot and dry here. Some of my plants are not coping well at all.

If it's any consolation, zucchini is a very tough plant and I'm sure you'll still have more than enough when harvest time comes!:hi:

2. Your plants may have aq substance abuse problem

if it's a white powder.

3. It could be a fungus. You can get a spray that would treat them.

I also heard that baking soda and water works as well. Mix it and put it in a spray bottle and spray the leaves.

4. you have "powdery mildew"

you need to treat them with a "safe" fungicide to start.

If you can, use a soaker hose around the plants and try to avoid getting the plants themselves wet. Also, they need air circulation to dry out between waterings -- if they're not drying fast enough, slow down the watering a bit.

5. Powdery mildew

doesn't have much to do with moisture conditions, although abundant light helps to keep it away. Nevertheless, certain species (especially roses) just are susceptible. Get a powdery mildew medicine at your plant store, there is stuff you can spray on, but it's proably not for edibles..

For vegetables, I just ignore it, (unless it gets on the fruits) because the leaves are dying off by the time you have the fruits, and it's normal for them to sicken and die off. It won't really hurt the harvest. I also heard a mild vinegar solution, or bicarb of soda solution (PH issues) can be effective for this in edible plants.

However I have found powdery mildew an frustrating and unsolvable problem once it gets in the garden. The best solution is to remove the plant and try for a more disease resistant variety next time. The area may also be contaminated, so change out the soil or solarize (cover the area with black plastic for several weeks allowing the heat produced under the plastic to kill pests and weeds.)

6. powdery mildew seems to be normal on Zucchini

I don't believe that it's detrimental to the plant,just try to keep the leaves from getting wet while you water.As a side note "my walla walla onions are ready, time to eat some hot dogs(onion vehicles)YIPPEE!!":hi:
