Downy mildew (Peronospora belbahrii) is a major disease of sweet basil (Ocimum basilicum). We examined the effects potassium, calcium and magnesium, individually in combination, on downy (SBDM) potted plants under commercial-greenhouse conditions over six growing seasons. An increased K concentration fertigation solution SBDM severity, whereas foliar-applied KCl K2SO4 suppressed SBDM. The appli...

Edamame, also called mao dou in China, is a large-seeded (seed dry wt. >250 mg/seed) green vegetable soybean [Glycine max (L.) Merr., Fabaceae] cooked and served in pods as snack-like peanuts (Arachis hypogaea) (Shurtleff 2001). In Asia, where edamame is an important vegetable (Fig. 1), farmers harvest stems with fresh green pods before full maturity when pods are fully filled, nearly 80% matur...

Titanium dioxide was used as a photocatalyst to decompose interfering substances for a quantitative analysis of a fungicide (iprodione) in dry basil by HPLC. A quartz vial containing basil extract and titanium dioxide was irradiated with black light. The interfering substances were almost completely decomposed by 180 min of irradiation, whereas 88.3% of iprodione remained. The recovery of iprod...

Four essential oils [Sweet Basil (Ocimum basilicum L, Fam: Lamiaceae), Geranium, (Pelargonium graveolens, Geraniaceae), Lemongrass (Cymbopogon citratus, Poaceae) and Peppermint (Mentha piperita L. Lamiaceae)] were selected to be converted into oil nanoemulsions (EONE). The four analyzed in their natural (EO) nano form (EONE) using GC-MS, the results showed a significant increase percentage of m...

The purpose of this study was to evaluate the essential oils from sweet basil (Ocimum basilicum, OB) as skin permeation enhancers to promote the percutaneous absorption of drugs. The in vitro and in vivo irritancy of the essential oils was also examined. Terpenes with various carbon numbers (mono-, sesqui-, di-, and tri-) were identified in both the lower-polarity fraction (OB-1) and higher-pol...
