Abstract

Ginger (Zingiber officinale) is an important spice crop of India. This crop is affected by different disease of which soft rot and bacterial wilt are the most important and destructive in nature. Being soil borne in nature, it is very difficult to control these diseases with chemical methods. So, an eco friendly approach consisting of six treatments i.e T1= Soil treatment by biofumigation using cabbage, T2= Soil treatment using bleaching powder @ 10g/bed, T3= Rhizome treatment by heat, T4= Rhizome treatment by rhizobacterial antagonist, T5= Rhizome treatment by endophytic bacterial antagonist, T6 = Control, was carried out at UBKV, Pundibari, Coochbehar to manage both the diseases efficiently. Among all the 6 treatments, it was found that biofumigation treatment of the soil with cabbage residues (T1) resulted in the lowest soft rot and bacterial wilt disease incidence of 9.97% and 5.92% respectively with a highest yield of 15.16 t/ha. T2, T4 and T3 also produced lower bacterial wilt disease incidence of 8.23%, 8.54% and 9.41% respectively. The highest bacterial wilt disease incidence of 22.11% and lowest yield of 770 t/ha was recorded by T6 (Control). It was concluded that soil sterilization was more beneficial than seed treatment alone and both seed as well as soil treatment should be practiced to manage them efficiently.
