“…The first step of this study was to check whether the treatment has any fungicide effect and interfere with the growth of the fungi. Contrary to observed with Azadirachta indica, Zingiber officinale or Salvia officinalis extracts against Sclerotinia (Ojaghian et al 2014;Pansera et al 2008), or other plant pathogens (Dorantes et al 2000), the mix extract of M. tenuiflora and Q. robur is unable to inhibit the mycelial growth in vitro or the germination of sclerotia. These results suggest that this extract is not toxic to the fungi, and its possible mode of action is not related to fungicidal or fungistatic effects.…”

Extract of Mimosa tenuiflora and Quercus robur as potential eco-friendly management tool against Sclerotinia sclerotiorum in Lactuca sativa enhancing the natural plant defences

The effectiveness of some plant extracts to protect against pests enhancing the natural defensive responses of the plant has been reported. Plant extract of Mimosa tenuifloraand Quercus robur has promising potential to reduce the incidence of a wide range of phytopathogenic fungi due to its antimicrobial compounds. In this study, we aimed to elucidate the effectiveness and mode of action of this mix extract in Lactuca sativa against Sclerotinia sclerotiorum. To achieve this objective, 4 weeks old lettuce plants of cv.Romana were treated with 2 cc l -1 of the plant extract either by soil drench or foliar applications 72 hours before the inoculation. The treatments were able to significantly reduce the progression of the pathogen, decreasing the diameter of the infection by 32% and 17% in foliar and soil drench application, respectively. Moreover, the results showed significantly higher levels of hydrogen peroxide (H2O2) as well as callose deposition in plants treated and inoculated compared with non-treated plants. However, no direct effect on the fungus growth was observed in vitro suggesting that foliar and root treatments with M. tenuiflora and Q. robur extract significantly reduce the infection of S. sclerotiorum in leaves of lettuce, through the strengthening of the wall mediated by the deposition of callose and the release of H2O2. The fact that the treatment enhances different processes involved in plant innate defense indicates that this treatment is acting as a resistant inducer, and could be effective against different microorganisms.

Sage species belong to the family of Labiatae/Lamiaceae and are diffused worldwide. More than 900 species of sage have been identified, and many of them are used for different purposes, i.e., culinary uses, traditional medicines and natural remedies and cosmetic applications. Another use of sage is the application of non-distilled sage extracts and essential oils to control phytopathogenic bacteria and fungi, for a sustainable, environmentally friendly agriculture. Biocidal propriety of non-distilled extracts and essential oils of sage are w documented. Antimicrobial effects of these sage extracts/essential oils depend on both sage species and bacteria and fungi species to control. In general, it is possible to choose some specific extracts/essential oils to control specific phytopathogenic bacteria or fungi. In this context, the use of nanotechnology techniques applied to essential oil from salvia could represent a future direction for improving the performance of eco-compatible and sustainable plant defence and represents a great challenge for the future.

“…this result agree with (Al-Taisan et al, 2014) they found that, cinnamon oil produced the best result for reducing the sclerotinia rot disease incidence that produced 75% survival bean plants when compared with controls. essential oil of salvia officinalis reduced the sclerotinia rot disease of lettuce from 100% in control to 20% (Pansera et al, 2013). treating cucumber plants with olive oil, clove oil, nigella oil and rocket oil significantly reduced the percentage of powdery mildew incidence and severity compared with the control treatment.…”

Three concentrations i.e 1, 2.5 and 5% of five essential oils were tested to study their effect on growth of Sclerotinia sclerotiorum. Results showed that Clove and Marjoram oils were inhibited growth of S. sclerotiorum. Under greenhouse conditions results revealed that amending vegetarian compost to soil increased the activity of all plant oils than the individual treatment in reducing disease severity of Sclerotinia rot. Clove oil alone or in combination with compost completely prevented the disease incidence. Seedling soaking with nigella, marjoram and clove oils and their combinations with or without compost against Sclerotinia rot disease. Clove oil combined with compost completely prevented the disease incidence in 2017 and disease severity recorded 2.36 % in 2018 growing season. Moreover, increase of fruit yield was recorded with the combined treatments between compost + clove oil then compost + marjoram and clove oils during growing seasons 2017 and 2018 respectively. All tested treatments positively increased the activity of peroxidase (PO), Polyphenol Oxidase (PPO) and PAL enzymes in cucumber. Moreover, chitinase and β 1,3glucanase were greatly increased in treated cucumber with treatments compared with control. The results of SDS (PAGE) showed that 15 protein bands with molecular weights ranging from 234.433 to 50.017 kDa are contained in cucumber plants. New protein bands expressed as a result of treating cucumber with plant oils. One band with 90.783 KDa was appeared in plants treated with marjoram and Clove oils, while absent in other treated plants.
