▎ 摘　　要

NOVELTY - Graphene oxide-pyraclostrobin nanosuspension agent comprises 30-35 wt.% active ingredient, 1-3 wt.% dispersant, 3-9 wt.% emulsifier, 4-6 wt.% anti-freezing agent, 0.05-0.15 wt.% thickening agent, 0.1-0.3 wt.% preservative, 0.2-0.4 wt.% antifoaming agent, and water (balance), the active ingredient is graphene oxide and pyraclostrobin compound in mass ratio of (1-9):(1-9). USE - The graphene oxide pyraclostrobin nanosuspension agent is useful for preventing and treating wheat scab (claimed). ADVANTAGE - The nanosuspension agent: improves biological activity, utilization rate and duration of active ingredients of pesticides; reduces amount and frequency of pesticide application; reduces pesticide runoff and accelerates residue degradation; provides a new way to improve the quality and efficacy of chemical pesticides, saves emission and reduce residual pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene oxide pyraclostrobin nanosuspension agent, comprising compounding graphene oxide and pyraclostrobin, then adding dispersant, emulsifier, anti-freezing agent, thickening agent, preservative, antifoaming agent and water to obtain the mixture, and preparing graphene oxide pyraclostrobin nanosuspension agent by ultramicro crushing method.
