Ideal for all brassicas
5 Stars
Ideal for all brassicas
A wonderful solution to my cabbage worms problem. As you can see from the picture, my red Russian Kale was being devastated by cabbage moths, basically skeletonized. I applied this spray according to the instructions and applied about 2-3 times within the course of 10 days (we had rain, and I wanted to make sure it stayed on the leaves). My kale completely recovered and is growing lush and strong!I do not recommend spraying this on herbs like dill or parsley, because you may be killing big butterflies like the swallowtail, who lays eggs on it.But if your brassicas look like swiss cheese, this is the spray for you. Easy to use, smells kind of chemical-y, and has a strong emerald color when diluted.
