How to Rid Knockout Roses of Caterpillars

How to rid Knockout Roses of tiny green leaf eating caterpillars? We started noticing small holes, edges chewed off green leaves on stem. One bush in line of 4 is especially strong with thick green stalks, high growth, beautiful red roses, and recently acquired these tiny green caterpillars...really a problem now.

Apart from picking them off, a fungicide spray should do the trick.
