Effect of treatment of potato plants with ALG–WP–CNT microcapsules produced by extrusion, emulsification, and spray drying, and containing Pseudomonas chlororaphis VUPF506, on disease inhibition under greenhouse conditions. The experiment was arranged as a factorial in the framework of a completely randomized design with three replications. Error bars represent standard error, and letters indicate a statistical difference compared to the control (p < 0.05). Means with the similar letters in the same columns are not significantly different at 5% of probability level based on Duncan Multiple Rang Test.
