“…Similar results were observed by several investigators where medicinal plants extracts or oils highly reduced the growth of B. cinerea in vitro; the essential oils of T. vulgaris at the highest concentration (200 ppm) inhibited the MGR by 90.5 % [19]. In the same direction, oil extracts from thyme (C. capitatus) [20], and sage (S. officinalis) [21] inhibited in vitro mycelial growth of B. cinerea.…”

The effect of native medical plant "Clammy Inula" (Inula viscosa L.) in combination with a low dose of the fungicide iprodione (Rovral ® ) against gray mould disease (Botryis cinerea Pers.) was evaluated in vitro and in vivo. The results revealed that the plant extract had antifungal effect on mycelial growth rate and conidial germiation of pathogen isolates. The plant extract at the concentration of 1% -4% and the fungicide iprodione at the concentration of 0.2 -9 µg•ml −1 significantly reduced the mycelium growth and germination. In addition, the plant extract at the concentration of 2% -4% and iprodione at the concentration of 300 -600 µg•ml −1 significantly reduced the disease severity (%) on bean plants compared to the controls. The reduction of mycelium growth, germination, and disease severity was positively correlated with increasing plant extract and fungicide concentrations. The combination of a low dose of plant extract and fungicide at (EC 50 ) was able to reduce disease severity of gray mold by 84%. While, plant extract and fungicide alone reduced disease severity by 46% & 39% and by 70% & 76% for the isolate (Bo5-10 and Bc 99), respectively, compared with controls. The application of water extracts of I. viscose in combination of a low dose of an effective fungicide (iprodione) can be a feasible tool in reducing gray mould disease severity, but farther studies are still needed under field conditions to evaluate efficacy against the disease under field conditions.

“…Moreover, thyme essential oil and its main components have been also reported for fungicidal and antibacterial activities (Panizzi et al, 1993;Muller-Ribeau et al, 1995;Janssen et al, 1987;Kurita et al, 1981;Paster et al, 1990;Daferera et al, 2000;, but showed also herbicidal effects (Angelini et al, 2003;Tworkoski, 2002) and insecticidal properties (Duke et al, 1992;Regnault-Roger et al, 1993). As a mechanism of interruption of nervous system was found for thymol and carvacrol in insects (Ryan & Byrne, 1988), a similar mode of action could be supposed for the nematicidal action of thyme (Korayem et al, 1993).…”

“…Essential oils in thyme plant tissues and their components may be considered as main responsible of the biocidal activity of this species. Thyme contains a 1 -2 % of essential oils, mainly represented by the isomeric monoterpenoids thymol (30 -70 %) and carvacrol (3 -15 %) (Zambonelli et al, 2004;Reddy et al, 1998;Rustaiyan et al, 2000). However, other compounds are present as cymol, terpinene-4-ol, thymol-methyl-ether and caryophyllene (Fig.…”

“…Thyme essential oil is a common product, easy to produce and cheap. It was reported by numerous investigators to have strong fungistatic and fungicidal effect on several pathogens (Bhaskara et al, 1998;Camele et al, 2012). Therefore it could be considered a valuable candidate in order to provide a postharvest protection in strawberry, where the use of synthetic pesticides is prohibited in Europe by law (Mari et al, 2014).…”

Depending on commodity and region, postharvest diseases can cause considerable economic losses. Although effective against postharvest pathogens, synthetic pesticides have gained increasingly negative attention over the past years from the public opinion. Among natural fungicides, plant derived compounds such as essential oils (EOs), have become topic of increasing discussion over the last couple of decades as safe and ecologically friendly alternatives to synthetic pesticides. Grey mould caused by Botrytis cinerea is an important postharvest disease of strawberries and many other horticultural products. In the present study the antifungal potential of Thymus vulgaris essential oil was tested on individual strawberries artificially inoculated with Botrytis cinerea. Two dilutions of thyme essential oil, 200 µl/ml and 500 µl/ml, were applied to strawberry fruits and incubated for a period of 13 days. The dilution 500 µl/ml effectively suppressed fungal growth in strawberries for a period of 7 days, more than twice as long as the control group. Furthermore only one out of five replications in the 500 µl/ml treatment was visibly infected while the others remained free from infection for the entirety of the experiment. At experiment conclusion the strawberries in the 500 µl/ml treatment maintained a healthier shape, firmness, and colour compared to the control and 200 µl/ml treatment. This study has confirmed that the application of thyme essential oil could be an efficient biocontrol tool in postharvest stage.
