    I've read various methods of combatting the euyonomus scale. Which would be the best way to begin today (2/20/05) in central Oklahoma?

    Would hort oil not work?

    Happy to oblige ... Merit is labelled for scale, as well but I'd give it some time before using that.

    Euonomus scale should be sprayed with Volck in the dormant season.

    timing is the key issue here. I would first hit it with a good hort oil this spring. Then you need to spray during the season with a product of choice when in the crawler stage. It is hard to control if ot in this stage. I have found that Once a plant is covered it seems like all you can do is knock them back to acceptable levels but seems to always have them around. You need to check periodically for activity and treat as needed.

    there are two types of euonymus, those with scale and those that are going to get scale!

    The hort oil is a good start, use a systemic later on in the season. Consider replacing plant, they aren't that expensive.

    I am Reading either Oil or Merit. But what I am not Reading is the complete answer to the problem. Oil and Merit together will solve the problem in one shot. Oil will knock it down and Merit will keep it down. I believe Talstar mixed with the Oil is a waste of money. Oil will kill the crawlers and the adults by itself. Talstar will offer no systemic value or real longevity to the problem. Merit will offer no knock down, but it will add systemic and longevity.

    Have had excellent results with hort oil, followed up w/ merit. Soaps do an ok job too. Empede is a good one.
