Repellent activity of mixed formulation of two essential oil (lemon grass and clove oil) against grasshopper / Nur Amalina Othman

Two essential oils extracted from the plant species lemon grass (Cymbopogon citratus) and clove (Syzygium aromaticum) were involved in the repellent activity against the grasshopper. The mixture of the two essential oil showed the best repellency over the single essential oil. The aim of the study w...
