rose bushes

Question

I have a rose bush that got beetle bugs and I usually used imunox but used a product called eight. It has went down hill ever since.

Answer 1

Eight@ by Bonide has the same chemical as Sevin, and is highly effective on Japanese beetles. Used according to package directions, this product should not cause a decline in rose health. (I've used both Eight and Sevin for 20 years with no ill effect on plants.)
