Whitefly’s theth bane of my brassicas
For the last two years my winter brassicas have been plagued by whitefly. They reduce the harvest and leave lots of sticky black fungal disease. I’ve tried blasting off the leaves with a jet of water, then soaking the ground around the plants to drown them and this is partially successful, but they keep fighting back. This year I’ve been feeding brassicas on steeped comfrey juice, which has a terrible smell. I’m adding this comfrey solution to my pump sprayer in the ratio five parts water to one of comfrey. Using my sprayer I coat the whitefly-infested leaves with this liquid. Steeped rhubarb leaves is usually successful at keeping bu erflies at bay, so I’m hoping this smelly solution will have the desired effect. The leaves have been liberally coated and the aroma under the net is terrible! Let’s hope the whitefly get the smelly message and clear off!
Will my smelly solution beat whitefly?
