Antimicrobial activities of selected essential oils against Fusarium oxysporum isolates and their biofilms

M.C. Manganyi, T. Regnier, E.I. Olivier, M.C. Manganyi, more

South African Journal of Botany > 2015 > 99 > Complete > 115-121

Fusarium infections, such as keratitis, are becoming increasingly difficult to control due to the build-up of resistance of fungi towards conventional antibiotics. Resistance is further enhanced by their ability to form fungal biofilms. Poor storage conditions and inadequate cleaning of contact lenses often lead to corneal infections. The solution to problems associated with contamination and resistance...

A review on the use of essential oils for postharvest decay control and maintenance of fruit quality during storage

Dharini Sivakumar, Silvia Bautista-Baños, D. Sivakumar, S. Bautista-Banos

Crop Protection > 2014 > 64 > Complete > 27-37

Postharvest diseases are one of the major causes for the postharvest loss of horticultural fresh produce during the supply chain. The incidence of postharvest diseases can affect the quality and restrict the shelf life of the horticultural fresh produce. At present strict regulations are enforced by the fresh produce importing countries regarding the minimum pesticide residue levels in the edible...

Flavia Jofré Barud, María Pía Gómez, María Josefina Ruiz, Guillermo E. Bachmann, more

Entomologia Experimentalis et Applicata > 171 > 2 > 146 - 155

The sterile insect technique (SIT) is used to control fruit fly pests, such as the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Enhancing sexual competitiveness of mass‐reared sterile males can contribute to making this technique more effective. It has been shown that exposure to volatiles from essential oils (EOs), such as ginger root oil (GRO) and those...

Advances in mosquito repellents: effectiveness of citronellal derivatives in laboratory and field trials

Immacolata Iovinella, Beniamino Caputo, Pietro Cobre, Mattia Manica, more

Pest Management Science > 78 > 12 > 5106 - 5112

BACKGROUND Several essential oils, including citronella (lemongrass, Cymbopogon sp., Poaceae), are well‐known mosquito repellents. A drawback of such products is their limited protection time resulting from the high volatility of their active components. In particular, citronella oil protects for <2 h, although formulations with fixatives can increase this time. RESULTS We synthesized hydroxylated...
