Herein, nanostructured metal oxides of essential soil nutrient elements (i. e. CuO and CaO) with definite shape and size were simply synthesized and their pesticidal activities against cotton leafworm (Spodoptera littoralis) were explored for the first time. These metal oxide nanostructures represented novel economic and eco:friendly nano:pesticides for sustainable plant protection and might boost the nutrient content of soil. The ... Read more
