The purpose of this study was to assess in vitro the activity of four essential oils (Cymbopogon citratus, Eucalyptus citriodora, Lippia multiflora, Melaleuca quinquenervia) and the biobactericide Neco® on Gram-positive bacteria.The aromatogram and antibiogram were assessed by the agar well diffusion method and the Muller Hinton disk-agar diffusion method, respectively. Also, the minimum inhibitory concentration and the minimum bactericidal concentration were determined by the microdilution method in liquid medium.The aromatogram showed that the biobactericide Neco® induced the largest inhibition diameters (34.53 ± 11.82 - 43.92 ± 5.38 mm) of all strains combined, followed by the essential oils of Eucalyptus Citriodora (30.01 ± 3.02 - 41.89 ± 1.77 mm) and Lippia multiflora (20.72 ± 4.72 - 37.61 ± 2.80 mm). However, the essential oils of Melaleuca quinquenervia (19.99 ± 3.93 - 26.20 ± 13.27 mm) and Cymbopogon citratus (13.52 ± 3.59 - 29.08 ± 2.35 mm) had the smallest inhibition diameters. Moreover, the comparison of the activities of the aromatogram and antibiogram revealed generally that activities were higher with essential oils than with antibiotics.At the end of this study, the essential oils of Cymbopogon citratus, Eucalyptus citriodora, Lippia multiflora, Melaleuca quinquenervia and the biobactericide Neco® had an antibacterial activity on Gram+ bacteria.

“…Similar results were obtained in an in vivo study by Silué et al (2018) who showed that the use of NECO against Colletotrichum gloeosporioides, the agent responsible for cashew nut leaf disease at concentrations of 1000 ppm reduced the severity of the disease by more than 50%. Work by Kassi et al (2014) showed that NECO applications at 5mL/L reduced the impact of black banana cercosporiosis. The observed antibacterial activity of the Biopesticide NECO could be explained by the existence of active ingredients with very strong antibacterial properties that would act directly on the crop pathogens and on the propagation organs (Camara et al, 2007).…”

“…This property would be due to the action of phenolic compounds such as thymol which is the major component of the essential oil of Ocimum gratissimum from which NECO was formulated. Thymol is known to be toxic to microorganisms and is thought to target the cytoplasmic membrane and wall of these microorganisms (Kassi et al, 2014). Indeed, much work has highlighted the efficacy of phenolic compounds, particularly that of thymol which has a very broad spectrum of antimicrobial action (Ajouri et al, 2008;Bounatirou, 2007).…”

The tomato crop is confronted to numerous soilborne pathogens, including Ralstonia solanacearum, which considerably limits its production. In order to control this bacterium, a biological control approach has been considered by evaluating the efficacy of the NECO biopesticide against this bacteriosis. In vitro confrontations were carried out using a range of five concentrations of the biopesticide. In vivo, NECO solutions of 5 and 10 mL/L were incorporated into soil previously infested with R. solanacearum before transplanting tomato plants. Zones of bacterial growth inhibition were observed after the application of the NECO biopesticide. Results showed that the 20 mL/L concentration resulted in a higher inhibition rate. The biopesticide at the 10 mL/L concentration significantly reduced the incidence of bacterial wilt (54.05%) under in vivo conditions. The NECO biopesticide could be used as a control agent for Ralstonia solanacearum.

“…These different compounds could therefore be at the origin of its effectiveness. In addition, studies by Kassi et al (2014) showed that the NECO biopesticide had an antifungal effect on Deightoniella torulosa (SYD.) ELLIS, a banana leaf parasite.…”

Cashew (Anacardium occidentale L.), an important crop in Côte d'Ivoire is prone to many diseases, one of the most redoutable of which is bacteriosis caused by Xanthomonas sp. To limit the use of pesticides in the fight against this bacteriosis, an alternative solution based on the use of essential oils has been evaluated. Antibacterial tests were carried out in vitro with the essential oils of Eucalyptus citriodora, Cymbopogon citratus, Citrus limon, NECO (formulation based on the essential oil of Ocimum gratissimum) and a synthetic pesticide, the callicuivre. The smallest MICs (10 ppm and 60 ppm respectively) were obtained with NECO and the essential oil of Cymbopogon citratus. The highest antibacterial activities were obtained with the essential oil of Cymbopogon citratus and NECO biopesticide. at the dose of 4000 ppm (for inhibition diameters of 20.67mm and 27.33mm respectively). NECO and the essential oil of Cymbopogon citratus could be used as an alternative to the synthetic product in the fight against bacteriosis of cashew.
