Abstract

Jatropha curcas L., a multipurpose oilseed plant, is very important for biodiesel production; it also has a wide range of bioactive compounds with medicinal properties and biocidal activity for control of crop pests and diseases. This review presents the state-of-the-art of the biocidal activity of J. curcas extracts. Chemical constituents such as phorbol esters are responsible for high bioactivity of J. curcas, due to their toxicity to humans and animals and to their high fungicidal and insecticidal activity. The fungicidal activity of these constituents may be due to destroy endoplasmatic reticulum and hyphae cell walls. The activity of these compounds on insect pest metabolism is well known, leading to an antifeedant effect, repellency, mating inhibition, oviposition inhibition or suppression and/or induction of infertile egg production, and inhibition of larva, nymph, and pupa development. Several studies have shown that although all organs of J. curcas plant are toxic, the degree of toxicity varies in accordance with the extract formulation, the nature of the active substance, the administration rate and procedure, and the individual sensitivity of pests and diseases. Thus, J. curcas stands out as a promising species for bioenergy purposes, as well as for control of pests and diseases that affect agriculture production.

Highlights

The Jatropha genus (Euphorbiaceae - Platiobeae subfamily) has more than 70 shrub-like species, such as J. pohliana, J. gossypiifolia, and J. curcas (Xu et al, 2012)
The aim of this review is to offer a broad perspective on the state-of-the-art of the biocide activity of Jatropha curcas L extracts
Studies on extracts of Jatropha curcas have shown that this plant exhibits considerable promise for formulation of new biocides

Summary

Introduction

The Jatropha genus (Euphorbiaceae - Platiobeae subfamily) has more than 70 shrub-like species, such as J. pohliana, J. gossypiifolia, and J. curcas (Xu et al, 2012). Easy propagation, and adaptation to many environments are some of the traits that favor wide distribution of the plants of this genus. The stem with multiple branches holds inflorescences, which appear at the beginning of the rainy season. J. curcas is widely distributed and is found at altitudes ranging from sea level to 3000 m, in regions with annual rainfall from 250 to 2500 mm. It requires a temperature between 18 and 28 °C (Dias et al, 2012). As a hardy oilseed plant that develops under adverse dry and rocky soil conditions, it may be useful for recovery of degraded areas
