Identifying a Turnip leaf pest

[gg_1899]

Hi,
Some of my turnips are showing the damage visible in the attached image. It's fairly minor as I've had crops mature to nice and edible turnips. But I'd like to know how to possibly treat this, in case it becomes a bigger problem.

Thank you

I love to grow turnips...in fact just started a big patch of them.

The damage like you show in that picture I would probably ignore as it doesn't seem to hurt the eventual production much.

However, if it got worse and/or I wanted to stop it I would use a spinosad product such as this:
