A new scourge is now ravaging my pumpkin plants... just not my year it seems. When I left prior to my vacation, I noticed that there were white spots on my leaves. I thought it was scale, but the Sevin I sprayed prior to leaving didn't work apparently. Now one week later, my plant is being ravaged by this stuff and I have no idea what it is, because the Sevin didn't work at all. Any thoughts or suggestions? I'm about at my wits end with this, nature has thrown just about everything at me this year.
