Evaluation of Organic Amendments Against Ralstonia solanacearum Causing Bacterial Wilt in Ginger

Abstract

The present field study was undertaken to investigate the effective organic amendments against Ralstonia solanacearum under pot culture condition. The average (PESR+PESM) reduction in mortality recorded with all the organic amendments tested were ranged from 15.39 to 64.97% over untreated control. However, significantly highest reduction in average mortality was recorded with karanj cake (64.97%). This was followed by the organic amendments viz., neem seed cake (43.95%), farm yard manure (37.36%), vermicompost (32.95%), poultry manure (32.24%) and sunflower seed cake (26.87%). Whereas, safflower seed cake (21.40%), goat manure (19.28%), cotton seed cake (18.60%) and groundnut cake (15.39%) were found less effective. All the test amendments improve root length, shoot length and vigour index in ginger. Among the different amendments tested, significantly highest root length (6.16 cm), shoot length (12.56 cm) and vigour index (1372.73) were recorded with Karanj cake. The second best amendment found was neem seed cake (5.26 cm, 10.26 cm and 931.20) respectively. This was followed by the amendments viz.

Effects of Solid and Liquid Vermicompost Application on Bean Growth and Common Bacterial Blight Disease in Different Growth Medium

Edwards and Arancon (2004) and Simsek-Ersahin (2011) stated that the effect of vermicompost applications to inhibit plant diseases is biological, rather than chemical.…”
