There comes a time in a person’t life when they need to throw in the towel, admit defeat, run up the white flag…In this case, run up the white-fly flag!
I’ve decided that drastic measures were needed to salvage plants for the fall: I chopped off all leaves from the kale and collards, and went through the brussel sprouts and cut off any leaves that were loaded with eggs. This way, i’ve gotten rid of the eggs, and can concentrate on any returning adults (and the predators will be hungry). I’ve done strategy this in the past, and the plants recovered. Once whitefly gets a hold of things, you’re finished: the leaves get scarred enough that i’m not going to eat them anyway.
The beneficial insects have really exploded recently in response to all the whitefly larvae available, and are keeping the pests at bay on the brussels sprouts: which is great cause i really don’t want to loose them!
