Abstract

Various European and national plans aimed at reducing the use of synthetic plant protection products have been implemented in response to the risks posed by their use for human health. These plans encourage the use of alternatives with the establishment of new categories of ‘pesticides’ in European legislation as basic substances.

The basic substances, defined by article 23 of Regulation (EC) No 1107/2009, are for the most part plant extracts. The Technical Institute of Organic Agriculture and Food (ITAB) is involved in several projects to promote organic farming. The Natural Agroecological Inputs for the Overseas Departments (INADOM) project, piloted by the ITAB, aims to have plant extracts approved at community level for the DROMs. Thus the extracts of Allium fistulosum, Ocimum gratissimum, Piper nigrum, Psidium guajava L., Quassia amara L., Moringa oleifera L. and Zingiber officinale, were proposed in this project from a list of plants and were the subject of an assembly of "Basic Substance" type files. In this presentation, the qualitative and quantitative differences of these extracts in bioactive compounds will be mentioned.

The variation in phenolic, alkaloid and terpene compounds of each extract results in the existence of a fungicidal effect for all the extracts and an insecticidal effect for the majority. Alone, the Piper nigrum extract does not show any fungicidal or insecticidal effect but rather a repellent effect for mammals (dog/cat).

The study of plant extracts offers a real opportunity to develop alternative and local solutions for farmers.

Keyphrases: Basic substance, extracts, Fungicide, INADOM, insecticide
