The invention provides a bounce-resistant fluazinam suspension agent. The bounce-resistant fluazinam suspension agent comprises: fluazinam, a wetting agent, a dispersing agent, a thicker, a preservative, an antifreezing agent, a suspending assistant, a defoaming agent, a bounce-resistant agent, a bounce-resistant synergist and water. The preparation method of the bounce-resistant fluazinam suspension agent comprises the process steps of mixing, sanding and the like. The particle size of the suspension agent is controlled to be 5 mum or below, and the suspension ratio is more than 90%. The preparation has the characteristics of low dynamic surface tension, good bounce resistance, strong adhesion and the like, and the bounce loss of a fluazinam solution can be reduced on surfaces of leaves,so that the utilization rate of the pesticide is improved greatly, and the dosage of the pesticide is reduced under the condition of ensuring the same pesticide effect; in addition, the cost of pesticide application of a farmer is reduced, and pollution to the environment is reduced.
