Abstract:

The study was carried out in the Laboratory of Entomology, Faculty of Agriculture, Sylhet Agricultural University, Sylhet during October to December 2014 with a view to assessing the effectiveness of four indigenous plants powder as protectant of stored chickpea seeds from the attack of pulse beetle (Callosobruchus chinensis L.). Plant powders were prepared from neem leaf (Azadirachta indica), black pepper (Piper nigrum L.), clove (Caryophyllus aromaticus L.) and methi (Trigonella foenum graecum L.). Three doses of all four plant powders @ 5 g, 10 g and 15 g kg-1 of chickpea seeds were used to determine the oviposition inhibition, adult emergence (%), adult mortality (%) and seed weight loss (%) due to the attack of pulse beetle. All three doses of clove powder were found to be most effective in protecting chickpea seeds from the attack of pulse beetle, in terms of eggs laid (0), egg bearing seeds (0), adult emergence (0%) and seed weight loss (0%). In respect of above four parameters other treatments had negligible effect having no significant difference with the control. The result indicated that all three doses of clove powder could be used as protectant of chickpea seeds in storage. Low dose (5 g clove powder for 1 kg of chickpea seeds) could be preferable to other two higher doses (10 g, 15 g clove powder for 1 kg of chickpea seeds) in respect of lower cost involvement. Because low dose was found to be effective, year-round experiments could be undertaken to determine the effectiveness of some lower clove powder doses than that of 5 g clove powder kg-1 of chickpea seeds.
