Tons of pests on Gai lan (Chinese brocolli)

aznboi385September 11, 2011

I saw some holes in my gailan(or kailan). I think it's categorized as a type of kale and also called chinese brocolli. I tried to take some pictures, but the quality isn't that good. It really had a whole bunch of different kinds of pests that I've never seen before. There were small green worms. Lots of dusty white specks that were ovalish; it almost seemed like mold. There was some holes in the leaf, but it was covered with some web looking like material. A last pest that I saw was this small black bug with yellow markings on its back. Sometimes I saw a pair of those black bugs walking with their butts stuck together (one walking backwards, one walking forwards. I think they were mating). There's so many pests on those veggies that I just cut them all down and threw them out. I really want to plant these and I was wondering how do I kill these pests so I can enjoy my gailan. Thanks in advance!

Green worm is in the middle bottom portion of the pic

The quality oaf your images isn't very good because you're too close to want you're trying to photograph.

The green caterpillars are most likely white cabbage moth. Handpick, flick into soapy water, or stomp. If you use Bt, the caterpillars MUST BE less than half grown.

The large blotches are caused by leafminers.

Again, regular patrols to spot the damage & ACT when you see it.

This time, the critters are between the leaf surfaces. So when you see the beginning of a blotch, gently squish the critter(s) which are snacking beyond the reach of any pesticide you might spray at it.
