Abstract

The research demonstrated the efficiency of aqueous extracts of seven plants [Garlic buds (Allium sativum), leaves of Sage (Salvia officinalis), leaves of black arum (Eminium spiculatum), leaves of Thyme (Thymus vulgaris), fruits of hot pepper (Capsicum annuum), leaves of Eucalyptus (Eucalyptus oleosa), and seeds of Clove (Syzygium aromaticum)], the extract demonstrated that Black arum had the largest deadly effects, with a 50% mortality rate at 10% concentration, whereas Red pepper had the highest mortality mean of 34.45% and the overall lowest mortality is 16.67% when compared to certain other aqueous extracts.
