Biocides formulation of essential oils having antimicrobial activity

Abstract

Essential oils of fennel, peppermint, caraway, eucalyptus, geranium and lemon were tested for their antimicrobial activities against some plant pathogenic micro-organisms (Fusarium oxysporum, Alternaria alternate, Penicilium italicum Penicilium digitatum and Botyritus cinerea). Essential oils of fennel, peppermint, caraway were selected as an active ingredient for the formulation of biocides due to their efficiency in controlling the tested micro-organisms. Successful emulsifiable concentrates (biocides) were prepared from these oils using different emulsifiers (Emulgator B.L.M. Tween20 and Tween80) and different fixed oils (sesame, olive, cotton and soybean oils). Physico-chemical properties of the formulated biocide (spontaneous emulsification, emulsion stability test, cold stability and heat stability tests as well as viscosity, surface tension and pH) were measured. The prepared biocides were ready to be tested for application in a future work as a safe pesticide against different pathogens.

Alternaria alternata (Black Rot, Black Spot)

“…Previous studies were conducted to test the antimicrobial activities of essential oils of fennel, peppermint, caraway, eucalyptus, geranium and lemongrass against some plant pathogens including A. alternata (Abo-El-Seoud et al, 2005). The results of this study confirmed the antimicrobial activity of the essential oils against the fungus.…”

Antimicrobial action and anti-corrosion effect against sulfate reducing bacteria by lemongrass (Cymbopogon citratus) essential oil and its major component, the citral

“…Different essential oils of plants have been shown to have an antimicrobial activity (Abo-El Seoud et al 2005; Bajpai et al 2009; Bakkali et al 2008; Khan and Ahmad 2011). In medicine, essential oils extracted from plants present antimicrobial activity against a range of bacteria including known antibiotic resistant strains (i.e.…”

Effect of Fatty Acid Methyl Esters on the Herbicidal Effect of Essential Oils on Corn and Weeds

“…In various industries, FAMEs are considered to be good adjuvants (Salimon et al 2012; Wang et al 2015), as well as effective solvents for EOs (Abo El-Seoud et al 2005). FAMEs are also important components of modern biodiesels (Giakoumis 2013).…”
