CLOSED: What is this white stuff on my Rosemary?

Long Island City, NY

Hi all,

Here are a couple of pics of something that's covering about 1/3 of the upper leaves of our rosemary plant. This is an indoor plant, but we got it from the farmer's market. I'm afraid to go near the plant, as any disturbance results in a veritable fog of this dust - and I don't want it infecting my other plants!

What is it, and what are some eradication techniques?

Any help is much appreciated :)

Powdery Mildew...lots of home remedies...(weak milk solution, baking soda solution etc, etc.

Very common on indoor Rosemary...fix it, give it good air circulation, move it outside as soon as you can-should be fine.

Thanks! I really didn't expect an answer that quickly :)
