How do i control caterpillars on a crop of cabbage plants. They were planted about a month ago and were doing really well but have since being savaged by caterpillars. I don’t think these plants can be salvaged but if i plant another batch how do i protect them? They were planted outdoors and were protected by netting.
The natural remedy is based on a bacterium but this can be hard to source, Chemical sprays containing short life pyrethrins include: BugClear Gun! For Fruit and Veg and Py Spray Garden Insect Killer
