Abstract

A field experiment was conducted during Kharif 2011 at Central Research Farm, SHIATS, Allahabad, Uttar Pradesh under rainfed condition to study the relative efficacy of bio-pesticides of different Neem products (leaf extracts @ 2.5 and 5.0 %, seed kernel extract @ 5%, oil @ 1%) and two fungicides (Ergon 50 SC @ 0.1% and Bavistin 50 WP @ 0.1%) to control Cercospora leaf spot (Tikka disease) of groundnut caused byCercospora arachidicola and Cercosporidium personata. All the bio-pesticides and fungicides were significantly superior in controlling Tikka disease of groundnut over check. The efficiency of bio-pesticides and fungicides to control Tikka disease was in order of Ergon 50 SC @ 0.1%> Bavistin 50 WP @ 0.1%> Neem leaf extract @ 5 %> Neem seed kernel extract @ 5%> Neem leaf extract @ 2.5 %> Neem oil @ 1%.
