PLANTS AND SEED TREATMENT WITH FUNGICIDES TO CONTROL RHIZOME ROT OF GINGER

Abstract

Altogether, two experiments were conducted in the research field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of March, 2012 to January, 2013 to control rhizome rot of ginger. In the, first experiment, ginger was intercropped with turmeric and okra as alternate row or alternate seed within the row. In the, second experiment, seed rhizome was treated with fungicides namely, Melody Duo, Dithane M-45, Folicur EW 250, Antracol 70 WP and Secure 600 DG before sowing of rhizome. Intercropping of ginger with okra and turmeric enhanced germination, superior plant growth and healthy plants. The treatment where ginger was intercropped with okra as alternate row performs the best results by reducing the disease severity of ginger and improves the plant growth. Better yield of ginger was also obtained where ginger was intercropped with okra as alternate seed, which showed a total rhizome yield of about 1.69% more than the control plot. Fungicide Antracol, Folicur and Secure proved their efficiency to increase rhizome germination, better plant growth, the highest number of healthy plants by reducing the incidence and disease severity of rhizome rot of ginger. Consequently, rhizome yield was much higher in Antracol and Folicur treated plants than control treatment. It can be concluded that rhizome rot of ginger can successfully be controlled by seed treatment with Antracol, Folicur and Secure.
