Indonesian farmers generally cultivate crops using a monoculture system. Monoculture cultivation has a major drawback, namely that the spread of pests and diseases (plant pests and pathogens) occurs more easily and rapidly. This study aimed to determine the incidence and severity of plant diseases in a polyculture system consisting of eggplant, cucumber, maize, and yard-long bean. The research employed a Randomized Block Design (RBD) with four treatments representing four crop species—eggplant, cucumber, maize, and yard-long bean—each replicated six times. The results showed that each crop in the polyculture system was still infected by diseases caused by different pathogens, with only one pathogen found in more than one crop. Eggplant was infected by Cercospora sp. and Fusarium sp., cucumber was infected by P. cubensis and Fusarium sp., maize was infected by Puccinia sp., and long bean was infected by U. appendiculatus. Disease incidence and severity varied among crops and continued to increase throughout the weekly observations. The highest disease severity was recorded for Fusarium sp. infection on cucumber, whereas the lowest severity was also caused by Fusarium sp. but occurred on eggplant. These findings indicate that although polyculture systems may reduce the risk of widespread disease outbreaks, they do not fully prevent pathogen infection. Therefore, more effective pest and disease management strategies are required to suppress disease development in polyculture cropping systems. Keywords: Cercospora sp., Fusarium sp., Pseudoperonospora cubensis, Puccinia sp, Uromyces appendiculatus
