A field trial was conducted at the Pusa farm to manage the disease through chemicals and to find out the impact on quantitative and qualitative parameters. The disease incidence varied from 1.8 to 14.2 per cent during the course of study. Minimum (1.8%) disease incidence was recorded in the plot when setts treated and sprayed with carbendazim 50 WP which was found significantly superior over all the treatments. Among the treatments, T5 (setts treated and sprayed with carbendazim) was found significantly superior over all the treatments in respect of quantitative as well as qualitative attributes of the sugarcane in crop being cane height (280 Cm), cane weight (1.20 Kg), cane girth (2.6 Cm), number of internodes (22), number of clumps (124), number of tillers (700), number of milliable canes (510/plot), cane yield (113.30 tones/ha), brix per cent (18.4%), sucrose per cent (15.83) and juice purity (86%). The cost benefit ratio indicated that the setts treated and sprayed with carbendazim achieved higher returns of Rs/ha being 2,23,039/- followed by Rs. 1,61,124 and Rs. 140679 of T6 (Sett treatment with carbendazim 50 WP @ 0.1% + three spray with propiconazole 25 EC @ 0.1%) and T7 (Sett treatment with propiconazole 25 EC @ 0.1% + three sprays with carbendazim 50 WP @ 0.05%), respectively.
