Eco-friendly Management of Rhizome Rot (Soft Rot) Disease of Ginger under Pasighat Condition of Arunachal Pradesh

Rhizome rot of ginger, caused by Pythium aphanidermatum (Edson) Fitz, is a major constraint for the production of healthy rhizome, sometimes causing total failure of crop. Chemical control of this pathogen is not economical and non-ecofriendly. Thus, the treatment with bio-control agent (Trichoderma viride) may offer practical and economical alternative for eco-friendly management of this disease. The lowest disease incidence (18.00 %) was recorded in T5 - Rhizome treated with Trichoderma viride @ 10g/l of water + Three foliar sprays of Trichoderma viride @ 4 kg/ha followed by T4-Rhizome treated with Trichoderma viride @ 10g/l of water + Two foliar sprays of Trichoderma viride @ 4 kg/ha with disease incidence of 24.33 %. The highest disease incidence (86.33%) was recorded in T6 (control) which was raised without any rhizome treatment and foliar sprays.
