Vegetable quality dependent upon plant protection measures

The evaluation and registration of pesticides, new solutions to urgent problems in minor crops, as well as prognosis and recommended measures services are important requisites for a sustainable vegetable production. The examples of the carrot fly, the cabbage root fly and the cutworm show that research in the field of host-plant selection and sexual behaviour of pest insects can lead to new and efficient tools for the monitoring of their occurrence and density. Serious pest problems arise regularly and create new challenges. The successful solutions for the monitoring of key pests described here may provide clues to promising future research projects.
