I HAVE A POTENTIAL PROBLEM WITH MY DAHLIAS. YESTERDAY I NOTICED THAT THEY HAD A SMALL LAYER OR COATING ON THE LEAVES GIVING THEM A DUSTY APPEARANCE. WHAT COULD IT BE? I IMMEDIATELY SPRAYED THEM WITH A FUNGICIDE.

Greetings

It sounds like you may have a fungal problem called powdery mildew.
Most fungicides should cover it, but most of the time it is unneeded. Powdery Mildew exists on the leaves without in most cases harming the plant.
A common example of this is lilacs during the mid to late summer, they often become covered. In an extreme case it may block out the sunlight and keep the plant from processing its food. But it does not live off the host plant like other parasitic fungi, it just lives there.
It is often a sign that plants are crowded too close or there is not enough air flow in the area.

Hope this helps

Mike

Hey Plant Doc, isn't there a recipe
for some homemade stuff with baking soda
that can be sprayed on???????
One part of baking soda, to one quart...
**or something like that** [dunno]

Sorry, I have not heard of that one. I think I would kinda be afraid to put baking soda on a plant, I would think it would be phytotoxic, but that is just a guess.
Most of the time, I just look at it and say, Oh, WOW! I have powdery mildew! and just let it go at that. It rarely hurts the plants.
