In a joint effort by the Faculty of Sciences and Techniques (FST) of Tanger and the National Institute of Agronomic Research (INRA) of Tanger, a study titled “Assessment of pesticide use by determination of environmental indicators: case study of watermelon from Loukkos (Northwest Morocco)” highlighted the challenges faced by watermelon farmers in the vital Loukkos agricultural region.
Loukkos, known as one of the most significant agricultural areas in Morocco, thrives with intensive agricultural activities, including the cultivation of watermelon.
The region’s fertile lands have led to substantial yields, thanks in part to the intensive use of pesticides, which has proven effective in mitigating multiple pest attacks and diseases.
The study highlights the potential consequences of such widespread pesticide usage. While it undoubtedly boosts productivity and safeguards farmers’ economic interests, it raises concerns for both human health and the environment.
The survey, conducted on 41 randomly selected farms, revealed the diverse array of pesticide products used to combat various diseases and pests, such as powdery mildew, downy mildew, leafminers, and mites, which threaten watermelon crops.
Among the indicators used to gauge pesticide pressure were the number of treatments, treatment frequency, and quantity of active substances applied.
The results showcased a notable pesticide burden on the watermelon cultivation in the Loukkos region, with 26.54 treatments per cycle, 28.46 as the treatment frequency indicator, and 14.76 kg/ha as the quantity of active substances indicator.
The study does not delve into the analysis of potential pesticide residues in the watermelon, soil, or groundwater. It underscores the need for further research utilizing health and environmental risk indicators to provide a comprehensive understanding of the impact.
As the study aims to promote safer pesticide practices and facilitate the development of guidance and regulations for pesticide application, it emphasizes the significance of sustainable agricultural practices to protect both the environment and human health.
While the study’s findings contribute vital insights to agricultural practices in Morocco, it also notes the importance of continuous monitoring and strict regulation.
The ONSSA’s recent ban on 70 agricultural pesticide brands further reflects the commitment to ensure a safer and sustainable environment for future generations.
The results of this study will be instrumental in guiding future policies and practices in the Loukkos region and beyond, fostering a more sustainable and resilient agricultural sector.
