Abstract
Aims: To determine the effect of seed treatment and foliar spray of fungicide on rhizome rot of ginger.
Study Design: The study was laid out in a randomized complete block design with three replications.
Place and Duration of Study: The experiment was conducted at the plant pathology Field Laboratory Of Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during 2016-2017.
Methodology: Fungicide namely Contaf 5 EC @ 1ml/L water, Bavistin DF @ 1 g/L water, Companion @ 2 g/L water, Fiasta Z-78 @ 2 g/L water, Matco 72 WP @ 2 g/L water, Blitox 50 WP @ 2 g/L water, Cabriotop @ 3 g/L water were applied as seed treatment and foliar spray with one control plot (without fungicide). The total number of unit plots was 24 and the size of unit plot was 15 m × 7 m.
Results: Fungicide Cabriotop was found as the most effective in increasing plant growth and by reducing disease severity of rhizome rot of ginger. Among the treatments, capriotop exhibited least disease severity (45.08%) of rhizome and maximum yield (4.13 t/ha) of ginger as compared to control plot (69.04% disease severity and 0.33 t/ha rhizome).
Conclusion: Application of the fungicide Cabriotop may be recommended for better performance in controlling of rhizome rot disease of ginger.
