NOVELTY - Pesticide carrier comprises pesticidal active ingredient-loaded graphene oxide and polydopamine layer coated outside the graphene oxide layer. USE - Pesticide carrier used for plant protection (claimed). ADVANTAGE - The pesticide carrier has simple preparation and moderate reaction condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of pesticide carrier comprising mixing pesticide active ingredient with graphene oxide dispersion liquid, oscillation reacting for 0.5-12 hours, solid-liquid separating, obtaining solid i.e. pesticidal active ingredient-loaded graphene oxide, dispersing in buffer solution at pH 7.5-9.5, adding dopamine hydrochloride and reacting for 4-48 hours.
