Efficacy of Foliar Sprays for the Control of Alternaria and Cercospora Foliar Diseases of Niger Cultivar cv Gujarat Niger -1 under South Gujarat Condition

A field experiment with four replications was conducted at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari, Gujarat on the foliar diseases of GN-1 variety of Niger crop. In this experiment, six different fungicides have been evaluated to control the Cercospora and Alternaria diseases out of which, all the fungicidal treatments were significantly superior over the control. The least intensity of Cercospora and Alternaria leaf spot 13.62 PDI and 14.41 PDI was observed respectively in T6 (Carbendazim + Mancozeb 0.2%), which was followed by the treatment T1 (Carbendazim 0.1%) for Cercospora (17.03 PDI) and Alternaria leaf spot (17.32 PDI) respectively. However, in case of seed yield similar trend was observed. This study concludes that foliar efficacy is an important step in controlling the above diseases.
