I've got a few small sawfly caterpillars appeared on the leaves of my maincrop turnips yesterday. I've never seen them before there were masses of them, and obviously more are to hatch yet. I have Hallmark in the store ready to spray, but no point before they've all hatched.
Does anyone know how long they will take to hatch, or should I just spray now and follow up with another dose at the end of the week? Little damage yet, but I know they can devastate the crop very quickly.
