purpose: in this study the inhibitory effect of eucalyptus extracts as a natural and herbal antibacterial substance was evaluated against pseudomonas aeruginosa strains (8821m and atcc27853). material and methods: the mic (minimal inhibitory concentration) of alcoholic and aquatic extracts of eucalyptus was determined using the tube and agar dilution methods. the growth rate of pseudomonas aer...

Background Plant development is very plastic, being coupled to environmental cues. As sessile organisms, plants must be able to respond rapidly to environmental stresses such as changes in temperature and salinity, heavy metals and water deficit. Efficient stress response systems are prerequisites for plant survival and productivity [1]. Molecular chaperones (or Heat Shock Proteins – HSP) compo...

Mealybugs (Phenacoccus solenopsis) is a diverstating insect pect of agriculture crops, vegetables, fruits and ornamental plants. In the current study, impact synthetic pesticides (malathion, profenophos, bifenthrin), organic plant extracts (neem, tobacco eucalyptus) natural enemies such as lady bird beetle (Coccinella septempunctata), brumus beetle, (Brumus suturalis), spider (Cheiracanthium me...

In this study, we evaluate the olfactory responses of Mahanarva spectabilis adults to aqueous extracts from following non-host plants for pest insect: garlic (Allium sativum L.), rue (Ruta graveolens cinnamon (Cinnamomum verum J. Presl), lemongrass (Cymbopogon citratus Stapf.), clove (Syzygium aromaticum star anise (Illicium Hook.f), eucalyptus (Eucalyptus globulus Labill.), tobacco (Nicotiana ...

OBJECTIVES To compare the effects of a single nocturnal dose of 3 honey products (eucalyptus honey, citrus honey, or labiatae honey) to placebo (silan date extract) on nocturnal cough and difficulty sleeping associated with childhood upper respiratory tract infections (URIs). METHODS A survey was administered to parents on 2 consecutive days, first on the day of presentation, when no medicati...

The global call on the use of botanicals sequel to control of phytopathogenic microorganisms causing diseases of food crops most especially on rice has not been given attention in the tropics. A study was conducted to evaluate the antagonistic effect (in-vitro) of aqueous and ethanol extracts of Eucalyptus lameldulensis and Moringa oleifera leaves at different concentration (5, 10, 20, 40 and 1...

A liquid chromatography-diode array detection-electrospray ionization mass spectrometric (HPLC– PDA–ESI/MS/MS) method was used for separation and characterization of the phytoconstituents of the aqueous acetone leaf extract of Eucalyptus camaldulensis Dehnh (Myrtaceae). The employed method was optimized for separation, identification and quantification of fifty six compounds including ellagitan...
