Effect of Fungicides in Controlling Alternaria Blight of Cumin
Keywords:
Abstract
The experiment was conducted at Spices Research Centre, BARI, Shibganj, Bogra, Bangladesh during 2014-15 to find out the effective fungicides in controlling Alternaria blight of cumin. Four fungicides viz. Rovral 50 WP @ 0.2%, Companion @ 0.2%, Secure 600 W @0.15%, Sunvit 50 WP @0.5% and one control were used as treatment. Cumin line CN 026 was used in this experiment. Three fungicides reduced disease significantly over control. Alternaria blight ranged from 14.40 - 90.81%, while the lowest severity was recorded in Rovral 50 WP (0.2%) sprayed plots and the highest severity was recorded in control treatment. Rovral 50 WP (0.2%) gave the highest number of umbels/plant, number of umbel lets/plant, number of seeds/umbel, number of seeds/plant, weight of seeds/plant and seed yield (675.0 kg/ha) which was followed by Companion and Secure 600 W. Sunvit and control treatment did not produce any seeds.
