Abstract:
An experiment was conducted at B. A. Collage of Agriculture, Anand Agricultural University, Anand during 2022-23 to investigate different nine plant powders viz., orange peel powder, guava leaf powder, tulsi leaf powder, mint leaf powder, neem leaf powder, neem seed kernel powder, custard apple leaf powder, curry leaf powder and moringa leaf powder were evaluated as seed protectant against this pest. The result showed that the mixing of neem seed kernel powder and neem leaf powder @ 2.5 g/100 g pearl millet seeds was found the most effective against C. cephalonica as it achieved 93.88, 93.41 percent oviposition deterrence, 6.41, 6.59 days males longevity, 6.43, 6.64 days females longevity, 51.05, 51.61 eggs per female and 57.33, 60.00 percent viable eggs, respectively after seed treatment. The best treatment with (71.25%) reduction of adult emergence was achieved by neem seed kernel powder @ 2.5 g/100 g seeds. The sex ratio of males and females ranged from 1:1.00 to 1:1.02 in all the evaluated treatments. None of these plant powders tested at different doses, hampered the germination of pearl millet during storage periods of up to 65 days.
