“…The strong fungitoxic of these two products could be explained by the fact that active material, Carbendazim, is a compound interfering with the formation and/or operation of microtubules, blocking cell divisions and elongation of mycelial hyphae (Leroux, 2013). These results are consistent with those of Chand et al (2013) and Silué et al (2017a), which showed the effectiveness of Carbendazim in the control of the fungal Colletotrichum gloeosporioïdes. However, the fungicide based on Azoxystrobine was less effective compared to the two fungicides.…”

“…However, the fungicide based on Azoxystrobine was less effective compared to the two fungicides. Azoxystrobine inhibitory activity on the mycelial growth of Colletotrichum gloeosporioïdes was previously revealed by Chand et al (2013) and Silué et al (2017a). The two essential oils tested in vitro were also inhibited the fungus strain.…”

“…The synthetic fungicides were tested at concentrations of 1 ; 5 ; 25 ; 50 ; 100 and 150 µL/L. Each concentration was directly incorporated into a previously prepared PDA culture medium and cooled at 45 °C (Silué et al, 2017a). Essential oils were tested each at concentrations of 500 ; 1000 ; 1500 ; 2000 ; 2500 and 3000 µL/L.…”

Context and Objective: Anthracnose, caused by Colletotrichum gloeosporioïdes, represents the main disease of cashew in the north of Côte d'Ivoire. This study was conducted to assess the toxicity of three synthesis fungicides, Azoxystrobin, Carbendazim and Carbendazim+Chlorothalonil and two essential oils extracted from Cymbopogon nardus and Ocimum gratissimum against Colletotrichum gloeosporioïdes. Material and Methods: Fungicidal properties of these products were evaluated in vitro on mycelial radial growth of C. gloeosporioïdes strain, through six concentrations added to a PDA medium (Potato Dextrose Agar). At the laboratory test, an essential oil, Ocimum gratissimum and the synthetic fungicides based on Azoxystrobine and Carbendazim+Chlorothalonil were selected and tested in situ against anthracnose disease. Résults: After 16 days of incubation at 30 ± 2 °C, the mycelial radial growth of C. gloeosporioïdes was completely inhibited from 1 µL/L by Carbendazim, 5 µL/L of Carbendazim+Chlorothalonil, and 1500 µL/L by essential oil of O. gratissimum. After reeling mycelial disks, the minimum fungicidal concentration obtained was 25 µL/L for Carbendazim, 100 µL/L for Carbendazim+Chlorothalonil and 2000 µL/L for O. gratissimum. The study in situ showed a highly significant reduction of the incidence and the severity of anthracnose on the leaves by essential oil of O. gratissimum. Conclusion : The essential oil of Ocimum gratissimum can be used in biological control of the pathogen Colletotrichum gloeosporioïdes in cashew plantation.

“…As such, it holds great potential for use alone, or for integration into existing fungicides and control measures, for enhanced and with eco-and bio-sensitive performance. Incorporation of copper and CuO in fungicide for treatment against C. gloeosp have also been studied, with effects shown on mycelial growth [50]. Rampersad and Teelucksingh reported that increasing concentrations of copper fungicide inhibited spore survival for Colletotrichum isolates [34].…”

Antifungal Potential of Nanostructured Crystalline Copper and Its Oxide Forms

et al. 2020

Copper has been used as an antimicrobial agent for over a century and is now being added to commercial fungicides. Nanomaterials have attracted much attention due to the special properties they have over their bulk form. We studied nanostructured copper (Cu-NPs), investigating the potential for improved antifungal properties derived from its special properties and studied any effect that the oxidation of copper (CuO-NPs) may have. We conducted this research against Colletotrichum gloeoesporioides, a devastating pathogen to plants/crops worldwide. Research on the effects of copper on this fungus are limited. Our studies showed that nanoforms of copper had significant antifungal activities, with Cu-NPs offering the most sustainable efficacy and was more effective than its oxidative form (CuO-NPs). Scanning Electron Microscopy (SEM) images of the treated pathogen show that the hyphae had a swollen appearance, lost their filamentous structure, and the mycelia had a powder-like structure, indicating the probable destruction of the hyphal tubular cell wall. X-ray Difractogram (XRD) outputs showed substantial changes in the physical characteristics of the Cu-NPs after interaction with the fungus. This is the first report to demonstrate chemo-physical changes in the metal compounds, opening new insights for further studies on the mechanism of copper’s antifungal properties.

“…It is reported as one of the most widespread, severe, and economically important diseases for tropical and subtropical crops [ 3 , 4 , 5 , 6 ]. Members of the genus Colletotrichum have a wide distribution worldwide, and affect a wide variety of crops including cashew, bean, chili, passion fruits, mango, avocado, apple, coffee, and strawberry plants [ 1 , 2 , 7 , 8 , 9 , 10 , 11 ]. The disease’s symptoms can be seen on leaves and young fruits [ 12 ].…”

Immuno-Dipstick for Colletotrichum gloeosporioides Detection: Towards On-Farm Application

2022

View full text Add to dashboard Cite

Early and quick detection of pathogens are crucial for managing the spread of infections in the biomedical, biosafety, food, and agricultural fields. While molecular diagnostics can offer the specificity and reliability in acute infectious diseases, detection of pathogens is often slowed down by the current benchtop molecular diagnoses, which are time consuming, labor intensive, and lack the mobility for application at the point-of-need. In this work, we developed a complete on-farm use detection protocol for the plant-devastating anthracnose agent: Colletotrichum gloeosporioides. Our methods combined a simplified DNA extraction on paper that is compatible with loop-mediated isothermal amplification (LAMP), coupled with paper-based immunoassay lateral flow sensing. Our results offer simple, quick, easy, and a minimally instrumented toolkit for Colletotrichum gloeosporioides detection. This scalable and adaptable platform is a valuable alternative to traditional sensing systems towards on-the-go pathogen detection in food and agriculture, biomedical, and other fields.
