Abstract:

Laboratory studies were conducted at Department of Crop Protection, Agricultural College and Research Institute, Valavachanur – 606 753, Thiruvannamalai District to study the effect of plant powders tested against rice weevil, Sitophilus oryzae infesting sorghum. The experiment on ten plant powders 2 per cent, among them Acorus calamus 2 per cent rhizome powder was found to be significantly the best compared to other treatments. At four days after the treatment highest mortality was registered in A. squamosa 2 per cent (88.88%) which was followed by Eclipta alba (51.11 %), C. indica (46.6 6 %) and A. indica 2 per cent (44.44%) and whereas untreated control recorded only 17.77 per cent. At six days after treatment highest mortality was seen in A. squamosa (98.88%) followed by E. alba (78.88%) while in control 36.66 per cent mortality was recorded and same trend was observed at 7 DAT. The experiment on adult emergence was nil in A. calamus 2 per cent rhizome powder treated sorghum grains while 97 adult rice weevils emerged from untreated control. No grain weight loss was recorded A. calamus 2 per cent rhizome powder treated sorghum grains. No grain weight loss was recorded A. calamus 2 per cent rhizome powder treated sorghum grains and 60 days after treatment while 47.25 per cent loss was registered in untreated control.
