Abstract: The efficacy of eco-friendly and chemical pesticides, and attractant solutions against giant African snail on mulberry was evaluated at H. Kodihalli village of Mandya district of Karnataka during September 2016. Among the eco-friendly pesticides copper sulphate poison bait registered highest per cent snail mortality in both laboratory (100 %) and field situations (99.63 % over one week duration). Whereas, lime+crystal salt (2:1), burnt rice husk+crystal salt (2:1) and rice husk+Acacia concinna powder (8:1) were found effective as barriers against the snail in laboratory studies. Among the chemical pesticides evaluated in field condition thiodicarb 75 WP and copper sulphate poison baits registered 120.66 and 87.01 dead snails per 10 m² area, respectively against methomyl 40 SP poison bait, the standard check which registered 145.01 dead snails per 10 m² area. Among the attractant solutions tested using bucket traps, cane juice, jaggery solution, buttermilk and tender coconut water were found more efficient in trapping the snails.
