Effect of enzyme-response Mag@CMCS@CPSG film on rice sheath blight disease (caused by Rhizoctonia solani) control and rice quality

To find a precise, efficient, and safe method to control rice sheath blight disease (caused by Rhizoctonia solani ), this study used the natural product magnolol as fungicide. Based on characteristics of cell wall-degrading enzymes (CWDEs) released R. during early stages infection, Mag@CMCS@CPSG (magnolol@carboxymethyl chitosan@carboxymethyl cellulose, pectin, sodium alginate, glycerol) film was constructed release in response CWDEs. The increased toxicity against , decreased EC 50 from 7.33 μg/mL 4.37 μg/mL, effectively blocked invasion mycelia. Under stimulation CWDEs cumulative reached 75.62% after 96 h, index treated with significantly decreased. maximum field effect 72.47%, which not different that commercial preparation jinggangmycin; however, holding period better. reduced loss yield quality caused infection did cause phytotoxicity or residue. In conclusion, can achieve accurate green blight.
