Conception by a Process for Extruding Plastic Mulching Film with Cade Oil and Study of Snail Repellent and Anti-bacterial Adhesion Effects

In organic lettuce cultivation, snails can cause great economic loss. There is a lack of effective control methods for these molluscs. This work is focused on the development of a new agricultural plastic mulch material based on low density polyethylene (LDPE), as it is the most widely used polymer in plasticulture. The objective was to develop a new bio-based plastic mulch material that is insect repellent and anti-biofilm by incorporating a bioactive substance into the conventional formulation of the material. A new plastic mulching film made of 0.1% cade oil as was produced using the extrusion process. Bioadhesion tests carried out with aqueous suspensions of Escherichia coli and Pseudomonas aeruginosa show that this material is endowed with anti-biofilm effects. This study will demonstrate how to act by repulsive effect to Helix aspersa against this devastating mollusk in salads culture.
