Online published on 13 January, 2016. Abstract A total of 12 amendments evaluated (pot culture) as pre-sowing soil application (preventive) were found effective againstS.rolfsii. However, neem seedcake and mustard cake were found most effective with significantly highest seed germination(85.00 and 83.33%), respectively. These were followed by the amendments viz., castor cake (78.33%) and groundnut cake (64.44%). All the test amendments recorded significant reduction in average mortality (PESR and POSM) over untreated control. However, significantly highest average mortality reduction was recorded with neem seed cake (79.54%), followed by the amendments viz., mustard cake (75.04%), castor cake (68.22%) and groundnut cake (48.55%). All the test amendments tested improved the growth parameters viz., root length, shoot length and vigour index in chilli cv. Parbhani Local. However, neem seed cake gave significantly highest root length (8.81cm), shoot length (19.56 cm) and vigour index (2364.07). The second and third best amendments found were mustard cake (8.55cm, 18.54 cm and 2302.65) and castor cake (7.85 cm, 17.44 cm and 1980.97).
