Abstract
The aim of this research was to test how far garlic (Allim sativum) and fenugreek (Trigonella foenum-graecum) can divert insect pests away from the okra crop (Abelmoschus esculentus). The main crop okra and garlic and fenugreek as associated crops were sown on the 21st January, 2008, at the Experimental Farm of the Faculty of Agriculture, University of Khartoum. The experiment was executed in a completely randomized block design. Low numbers of jassid (Jacobiasca lybica) were recorded on okra intercropped with fenugreek (2.0) and garlic (2.1) compared with that recorded on the control plots (2.4). The okra plots intercropped with garlic harboured a lower number (0.07) of aphids (Aphis gossypii) than the control (0.1). Low numbers of whitefly (Bemisia tabaci) were recorded in okra intercropped with fenugreek (0.24) and garlic (0.55) compared to those recorded in the control plots (1.0). Both garlic and fenugreek did not show remarkable effect against the spiny bollworm Earias spp. Higher pod yield was obtained from plots of okra intercropped with fenugreek (360 kg/ha) and garlic (358 kg/ha) than those the control (315 kg/ha
