In order to sustain control over soybean root rot, wheat-straw-fiber-based mulch film (WFM) coated with carbendazim (C) and chitosan (CS) mixture (C-CS-WFM) were prepared through bar coating technology. The Box–Behnken design method was employed investigate the effects of concentration, wet thickness, loading on dry tensile strength (DTS), (WTS), air permeance (AP) C-CS-WFM. Eventually, optimization process parameters determined as follows: a concentration 1.83–2.39%, thickness 18–24 μm, 0.05–0.12 g/m2. These achieved desired physical properties C-CS-WFM, i.e., DTS is not less than 3.5 kN/m, WTS 0.8 AP does exceed 2.1 μm/(Pa·s). results showed that after introduction C-CS coating, C-CS-WFM enhanced by 11.4% 14.9%, respectively. contrast, reduced 15.6%. FT-IR analysis indicated embedded in composite material without any chemical interaction. Through SEM sustained-release kinetic analysis, it found mechanism conformed Ritger–Peppas model, its release diffusion matrix erosion. vitro antifungal test pot experiment demonstrated could effectively inhibit growth Fusarium solani promote plants. This study provided new ideas for comprehensive prevention rot.
