Abstract
The study determined the effect of alcoholic extract of common purslane, Portulaca oleracea, Java grass, and Cyperus rotundus oil in controlling the two-spotted spider mite on okra plants. The results of laboratory experiments showed the efficiency of purslane alcoholic extract was highly toxic to adult mites, but its effect was limited on eggs. In contrast, Cyperus oil was highly effective against mite eggs and adults. Cyperus oil gave the highest mortality of 86.94%, with significant differences from the purslane extract, where 68.61% mortality was observed and differed significantly from the control treatment. An increase in mortality increased with concentration, and the highest mortality of 95.83% was achieved at 5%, compared to the mortality of 59.58% at 1% treatment. The ovicidal activity was significant after the C. rotundus oil treatment compared to the purslane extract application. Cyperus oil reduced egg hatching by 42.50%. However, purslane extract did not affect the hatching significantly (91.70% hatching) and was not significantly different from the control. In general, the hatching rate decreased with increasing concentration of Cyperus oil and was only 40% at the 5% treatment compared to 60 and 96.70% at 1% treatment and controls, respectively..
