- To know the impact of pesticides on the soil/plant system and on the human health.
To know the impact of pesticides on the water system
To know the rules for pesticides utilization
To calculate the Predicted environmental concentrations of pesticides in soil and water.
To know new sustainable pest control strategies as alternative of the chemical pesticides
To know the biotechnological methods to manage the organic wastes and byproducts to produce organic fertilizers promoting circular economy. - Prerequisites
- The student is requested to know Chemistry and Organic Chemistry
- Teaching methods
- Lectures
Practices
Technical excursions
Seminaries - Learning verification modality
- Oral exams. The exam will have a 40 min duration aiming to ascertain the knowledge level acquired by the student. In particular, the student will demonstrate to know the legislation about the registration and the use of pesticides, the risks for the environment related to the use of pesticides and the best practices to reduce the risk. Moreover the student will have to know the natural products used as bio-pesticides and their mechanisms. Finally, the student will have to know the best practices for a biotechnological treatment of organic wastes and byproducts.
The exam allows to verify if the student is able to develop independent solutions to apply the best techniques to minimize the risk for the environment deriving from the use of pesticides and the management of organic wastes.
The dates are available in the web site of the DSA3. - Extended program
