BAC Foliar Nutrition ensures the quick creation of chlorophyll (green colour) in the leaf. BAC Foliar Nutrition stimulates the micro-organisms living on and in the leaf (photosynthesis bacteria) that ensure the creation of chlorophyll.
Furthermore, BAC Foliar Nutrition contains ingredients that make the crop uninteresting to enemies, such as thrips and spider mites. It will be much easier to keep these enemies at bay as they no longer like your crop. Prevention is better than cure.
