Information Publications

Aim of my PhD project is to develop pest control strategies based on mixed cropping for brassicaceous crop plants such as cabbage and broccoli. To meet his goal, I study mechanisms of air-mediated plant-plant and plant-insect interactions in agricultural field trials and in the laboratory. My work combines chemical ecology, agricultural plant science and entomology.
