I have a sawfly problem on all my hardy hibiscus plants every year .I want to prevent that this year .is this a good product for that and how and when should I treat
For prevention of and early spring treatment of rose sawfly, you can use a systemic product like Fertilome Tree and Shrub Systemic Insect Drench. For current sawfly larvae, you can use high pressure water spray to dislodge the insects and/or do a thorough coverage spray using a product such as Conserve SC. It is best to spray in early morning, and be sure you treat the undersides of the leaves where these insects hide.
