Intercropping, or the use of different aspects of the interaction between organisms in ecosystems, can be classified as an ecological method that limits harmful human interference in the environment, especially the consumption of chemicals. The impact of intercropping carrot with coriander Coriandrum sativum L. and summer savory Satureja hortensis L. on the occurrence of select carrot pests was estimated in the years 2010-2011. Intercropping had a significant effect on the decrease of the number of roots damaged by carrot rust fly Psila rosae. During harvest, the least number of damaged roots was observed in combination with summer savory S. hortensis L. The number of carrot psyllid Trioza viridula Zett. and aphids on carrot leaves and roots damaged by nematodes was significantly lower on plots where carrot was intercropped. Intercropping both herbs had a positive influence on the number of beneficial insects. In all of the years of the study, the highest number of Coccinellidae and Syrphidae were observed on plots where carrot was intercropped with coriander.
