Abstract
ABSTRACT Plasticulture has revolutionised Farming production. In salad cultivation, the snail is the main pest that can cause significant economic losses. The present study focuses on the design of a new industrial mulching material co-extruded separately with three essential oils: cade, turmeric and cumin oil. Experimental tests carried out on a pilot system confirmed the repellent effect against this mollusc and the protection of lettuce weight loss by about 30%. Adhesion tests by Escherichia coli and Pseudomonas aeruginosa demonstrate anti-adhesion properties of 80% when bioactive oils are incorporated into the industrial formulation of the plastic film. Application of the predictive theoretical approach confirms that the adhesion scores cannot be explained by the total adhesion energy and total hydrophobicity energy. This proves that these effects are the result of bioactive activity. This research work offers an innovative, practical and ecologically responsible alternative to protect lettuce crops against nuisances and pests.
