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

摘要

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.
