Abstract

The efficacy of three fungicides, ziram (Cuman L®), maneb (Dithane® M-45), and IBP (Kitazin®), in the control of brown spot disease of paddy (IR 50) was tested in a field trial. Four modes of application were used: (1) as a dressing for infected sprouted seeds; (2) as a root dip for infected seedlings; (3) as a single foliar spray to transplanted seedlings; and (4) as three foliar sprays to transplanted seedlings. Maneb was effective in controlling the disease in nursery beds (180 g a.i. 100-kg-1 of seeds) as well as in the seedlings (225 g a.i. 100-L-1 of water). For secondary airborne infection in the main field, three foliar sprays with IBP (48 mL a.i. 100-L-1 of water) at 15-day intervals after transplantation were effective; this treatment increased paddy yield significantly.
