Euonymus Scale

scottys(z6NY)June 12, 2010

I've identified scale on my rather large euonymus (it was actually there last summer too but I didn't know what it was).

Several websites I visted list Cygon, Malathion, Orthene or Sevin as treatment.

I was wondering, can anyone let me know if they also have used one of these with successful results?

Thank you.

I've used all of the above to control Euonymus scale. For Malathion and Sevin, sprays should begin when the crawlers are out and then repeated every 7 to 10 days for a couple of sprays. You could use a product containing imidacloprid or Safari. Many forms of those are root drench or applied to the soil. It's slower to work than a spray, but will last a lot longer inside the plant. In bad infestations, the plants can be cut back to the ground and treated when growth comes back out.

Stompede, Thank you.
I sprayed today with Orthene this morning and I'll repeat it every 2 weeks...hopefully that will do the trick.
