Kale Yellow Spots

Kale    None Given

My kale has yellow spots underneath and its killing my kale. Can you please tell me what it is and how to treat them.

********Update***********
The spots wash off with strong water pressure and a little rubbing and the leaf isn't damaged underneath. And a closer look at the kale revealed an infestation of worms (images attached).

Hi Carolyn, the yellow spots are not clearly visible in the image. Could you please upload some clear images. Thanks

I cropped the picture to give you a more in depth picture to possibly give me your opinion as to what the spots may be. Hopefully this will work because the original picture looks really clear on my end.

Carolyn, if this is a yellow liquid, can you check the plant tissue under with yellow spot? Is it water -like (just with yellow color) or sticky like bacterial exudate?

It looks unusual. It appears to be a liquid but squinting I would also think butterfly eggs. Of course, many butterflies lay eggs on kale and all are bad

Why do you say the kale is dying ?

I would use a high pressure hose/hand held sprayer with water and spray the area to remove this

Thanks David, I had decided this morning to wash them off and spray with some neem spray. I agree, it does appear to be some sort of liquid, I just don't know from where. That picture was of a healthy leaf, but I have a lot of dead leaves.

Thanks for the updates Carolyn. Agree with David, the yellow spots could be an egg mass of cross-striped cabbageworm. After hatching the larvae feeds on leaves by making holes and you can see green-brown frass (insect feces) on leaves. The caterpillar is green in color and hairy, with a velvet-like appearance; may have faint yellow to orange stripes down back.
