“…The use of rhamnolipid biosurfactants for plant growth promotion is well documented in literature owing to their detrimental effect on pathogens . The antifungal activity of rhamnolipid comes from disruption of fungal cell membrane . The findings in the present study also demonstrated the effectiveness of rhamnolipid in controlling C. falcatum in vitro as well as in vivo .…”

The rhamnolipid biosurfactant (RL-DS9) extracted from the bacterial strain Pseudomonas aeruginosa DS9 was evaluated for its antifungal activity against Colletotrichum falcatum that causes red rot in sugarcane. The surface tension (ST) reduction, biosurfactant production, and antifungal activity of biosurfactant against C. falcatum were investigated by using the medium with different carbon sources and it was found to be maximum in glucose. Moreover, highest reduction of ST and production of biosurfactant was achieved at 4.5% (w/v) concentration of glucose. The efficacy of RL-DS9 was compared with a commercially available rhamnolipid (RL-R95) using microtitre plate assay. Results showed that at 100 μg ml(-1) concentration RL-DS9 exhibited 86.6% inhibition against C. falcatum spore germination, and in the same concentration RL-R95 showed 83.3% inhibition. From liquid chromatography-mass spectrometry (LC-MS) analysis, it was revealed that only two similar congeners Rha-(C10 ) and Rha-Rha-(C10:1 ) were found to be in common among both the rhamnolipids. In the plant bioassay test, it was noted that red rot incidence was reduced on the sugarcane plants treated with RL-DS9. This is the first report that rhamnolipid biosurfactant produced by Pseudomonas aeruginosa DS9 could be able to control red rot disease of sugarcane caused due to the infection with the fungus Colletotrichum falcatum.

“…In recent decades, through growing concerns about adverse effects of frequently applied synthetic chemical pesticides and antibiotics, a variety of eco-friendly alternatives have been suggested for sustainable crop production against different pathogens ( McFeeters and McFeeters, 2012 ; Yuliar et al, 2015 ). Antimicrobial plant essential oils were suggested as eco-friendly agents to decrease the tomato bacterial wilt and grey mould.…”

Bacterial wilt and grey mould in tomato plants are economically destructive bacterial and fungal diseases caused by Ralstonia solanacearum and Botrytis cinerea, respectively. Various approaches including chemical and biological controls have been attempted to arrest the tomato diseases so far. In this study, in vitro growths of bacterial R. solanacearum and fungal B. cinerea were evaluated using four different vitamins including thiamine (vitamin B1), niacin (vitamin B3), pyridoxine (vitamin B6), and menadione (vitamin K3). In planta efficacies of the four vitamin treatments on tomato protection against both diseases were also demonstrated. All four vitamins showed different in vitro antibacterial activities against R. solanacearum in dose-dependent manners. However, treatment with 2 mM thiamine was only effective in reducing bacterial wilt of detached tomato leaves without phytotoxicity under lower disease pressure (106 colony-forming unit [cfu]/ml). Treatment with the vitamins also differentially reduced in vitro conidial germination and mycelial growth of B. cinerea. The four vitamins slightly reduced the conidial germination, and thiamine, pyridoxine and menadione inhibited the mycelial growth of B. cinerea. Menadione began to drastically suppress the conidial germination and mycelial growth by 5 and 0.5 mM, respectively. Grey mould symptoms on the inoculated tomato leaves were significantly reduced by pyridoxine and menadione pretreatments one day prior to the fungal challenge inoculation. These findings suggest that disease-specific vitamin treatment will be integrated for eco-friendly management of tomato bacterial wilt and grey mould.

“…Lavenders (Lavandula) are members of the Lamiaceae or mint family, which include many important essential oil producing plants including mints, sages and basil. Lavender essential oils have been found to possess diverse activities including medicinal, preservative, insecticidal, antimicrobial and antifungal properties; however, little has been done to investigate the potential for lavender essential oils in the control of postharvest diseases [6][7][8][9][10][11]. Essential oils and their constituents have shown diverse modes of action in controlling those pathogens against which they are effective.…”

A growing body of literature indicates that many synthetic pesticides have adverse effects on human, animal, and environmental health. As a result, plantderived natural products are quickly gaining momentum as safer and less ecologically damaging alternatives due to their low toxicity, high biodegradability, and good specificity. Essential oils of Lavandula angustifolia, Lavandula x intermedia cv Grosso, and Lavandula x intermedia cv Provence as well as various mono-and sesquiterpene essential oil constituents were tested in order to assess their antifungal potential on three important agricultural pathogens: Botrytis cinerea, Mucor piriformis, and Penicillium expansum. Fungal susceptibility testing was performed using disk diffusion assays. The majority of essential oil constituents tested did not have a significant effect; however, 3-carene, carvacrol, geraniol, nerol and perillyl alcohol demonstrated significant inhibition at concentrations as low as 1 μL/mL. In vivo testing using strawberry fruit as a model system supported in vitro results and revealed that perillyl alcohol, carvacrol and 3-carene were effective in limiting infection by postharvest pathogens.
