Fly ash, cow-dung ash, acacia bark ash, red soil powder and turpentine oil as post harvest grain protectants were tested for their insecticidal potency against pulse beetle (PB), attacking stored chickpea. The results revealed that fly ash at its application rate of 1.0 g per 50 g of grains showed the minimum days (5.06) to 100% mortality of released adults, minimum fecundity (0.86 eggs per grain), minimum holes (0.41 per grain), lowest number (3.14) of F1 adults emerged, maximum inhibition (78.62%) of F1 adults, minimum weight loss (9.63%) and the minimum of 2.86 days to 100% mortality of F1 adults. Fly ash and turpentine oil were the most effective at all application rates compared to other materials and the control. However, fly ash proved to be the best in managing PB infestation to lower levels followed by turpentine oil and cow-dung ash while red soil powder and Kikar (Acacia nilotica) ash were less effective and were similar to the control at their lower application rates.
