To improve biological control of B. tabaci , we investigated repellent properties of plant-produced semiochemicals. Carol Stream, USA: Allured Publishing Corp., 2001. Bioactivity‐directed chromatographic separation of the oil led to the isolation of 2‐tridecanone, 2‐undecanone and D‐limonene as active compounds. Abstract. The essential oil from the leaves and stems of the plant can be applied to skin, clothing and any gear being carried as a means to repel ticks. The essential oil was dried over anhydrous sodium sulfate to yield a clear yellow oil in 0.15% yield.
