What's eating my mustard greens 'golden streaks'?

Mustard Greens 'Golden Streaks' has feathery, deeply divided leaves that, while ornamental, trap aphid colonies in crevices and make thorough spray coverage difficult. Flea beetles, aphids, cabbage worms, and slugs are the key threats. The finely cut foliage is actually more easily damaged cosmetically by flea beetle shot-holing than flat-leaf types.

Perforated, lace-like appearance on the delicate divided leaves; cosmetic damage is very visible on this ornamental-use variety Row cover at sowing; kaolin clay spray; early morning hand-picking when beetles are sluggish

Colonies wedged into the leaf divisions; difficult to detect early and difficult to spray out; plant growth stunts Strong water spray from multiple angles; insecticidal soap; check plants twice weekly as colonies hide well

Feathery leaves eaten away; frass scattered among the fine leaf segments Bt-k spray every 7–10 days; hand-pick caterpillars which camouflage against stems

Overnight nibbling of fine leaf segments close to ground level; slime trails visible Iron phosphate bait; copper tape barriers; hand-pick after dusk; avoid overhead watering in evening
