Fungi under genus Trichoderma as ameliorates of biotic and abiotic stresses in cultivated crops is gaining popularity world-wide and their application in conjunction with seed coating polymers is an attractive proposition to reduce bioagent wastage and harnessing benefits of combined application. The synergistic action of Trichoderma with natural polymers like chitosan can enhance antimicrobial activity. A series of blended film solutions were synthesized by using chitosan, PEG and plasticizer in varying concentrations. The optimization of blended film composition and dose for coating of seeds was done w.r.t seed coating. Studies on compatibility of film forming ingredients with Trichoderma have not shown any inhibition and antimicrobial activity has shown different levels of inhibition of plant pathogens. Films were structurally characterized by XRD, SEM, FT-IR, TGA, DSC. The optimized film solution in combination with different Trichoderma strains improved seed quality parameters in test crop castor (Ricinus communis). Significant increase in vigour index (3110) was observed with Th4d treatment followed by chitosan and Th4d combination formulation (3023). In conclusion, the optimized chitosan-PEG-Th blend was effective in enhancing seed germination and plant growth of castor. The material can be further tested under large field evaluation as a seed coating agent against various plant diseases.
