Abstract
In agriculture, Carbon Dots (CDs) have been shown to enhance plant photosynthesis, boost antioxidant capacity and increase stress resistance. Additionally, CDs can serve as pesticide carrier, to improve the stability, solubility and targeted delivery of pesticide molecules. In this study, novel weed-based CDs derived from Commelina communis were developed. Using peas, Chinese cabbage, and aphids as the test objects, the CDs can promote the growth of seedling, within a certain concentration range, where they can significantly increase the fresh weight of plants. This growth-promoting effect is mainly due to the facilitation of iron ion absorption and the synthesis of chlorophyll by the CDs, thereby enhancing plant photosynthesis. In addition, CDs-flonicamid nanocomposite can improve the adhesion of pesticides on the leaf surfaces, and enhance the control effect against aphids. This work lays a foundation for the development of innovative pesticide formulation based on the CDs and their broader application in agriculture.
期刊介绍：
Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
