Generally, the medicinal plants have antifungal substances that can be used for the plant protection against phytopathogens. The objective of this study was to know the efficiency of aqueous extracts from medicinal plants against the major etiological agents of coffee tree. The aqueous extracts used were extracted from bulbs of Allium sativum, leaves of Vernonia polysphaera, Cymbopogon citratus...

Environmentally friendly botanical larvicides are commonly considered as an alternative to synthetic larvicides against Aedes aegypti Linn. In addition, mosquito resistance to currently used larvicides has motivated research to find new compounds acting via different mechanisms of action, with the goal of controlling the spread of mosquitos. Essential oils have been widely studied for this purp...

There are many unresolved questions concerning the health benefits of dietary antioxidants due in part to the complexity of the materials and mechanisms of action. We applied a new electrochemical method and report new observations for one of the richest sources of dietary antioxidants. We observed that the insoluble fraction of clove is redox-active and can be rapidly and repeatedly switched b...

The efficacy of 9 repellents (8 commercial repellents and one product under development) was evaluated on the skin at dosages of 0.65 and 1.7 mg of product/cm2, the latter dosage being the industrial standard for deet based repellents. The repellents were applied to the arm or lower leg of a human subject and tested against Anopheles stephensi in a cage or flying freely in a mosquito-proof room...

This research examined the effect of chemical factors (pH, sodium chloride, sugars (glucose and sucrose), preservatives (benzoic acid and sorbic acid)) and clove oil to decrease the growth of film yeasts (Saccharomyces cerevisiae J1, Candida krusei J2 and Candida krusei J3) on fermented bamboo shoots. All yeasts grew at pH 3.0-7.0 and did not grow greater than 7.5%(w/v) of sodium chloride conce...
