Abstract
This work has validated the use of two new natural biopesticides developed in the framework of the Life Waste4Green project on processing tomatoes.
These products are based on botanical extracts from agro-industrial waste and are effective against pests and diseases.
The aim of the study was to test the efficacy of the new products in the control of pests and diseases in processing tomato crops, replacing conventional chemical pesticides.
The trial consisted of 2 different treatments, based on the total substitution of chemical pesticides with Waste4Green products, partial substitution with both products, and a control treatment in which only chemical pesticides were used.
The trials were carried out at the Centro Tecnológico Nacional Agroalimentario Extremadura (CTAEX), Badajoz (Spain) during the 2022 and 2023 seasons.
In general, it was demonstrated that the substitution of chemical pesticides with the new products allows similar yields to those obtained with conventional products without affecting the main quality parameters of processing tomatoes, making it possible to obtain fruit free of pesticide residues.
The results suggested that the products developed in the project, which include botanical extracts of eucalyptus and oil mill residues, can be successfully applied to processing tomato crops at a dose of 5 L ha‑1.
