Abstract

Three consecutive years’ experiments were conducted at the organic coffee fields of Loyola Estate, Sirumalai near Dindigul District of Tamil Nadu, South India during 2013, 14 and 15 to evaluate bioefficiency of plant oils and leaf, garlic extracts against berry borers in the chosen organic coffee field. Among these plant oils tested, spot application of Neem and pongamia seed oils along with emulsifier was found to be very effective in the initial stage causing 90 to 94 percent reduction in borer population over control after three rounds of spraying in the final year. The overall borer population was found to be 90 percent reduced in the coffee plants sprayed with mixture of Neem with pongamia oil 3 percent and 2 percent of garlic extract even at the later stage of borer attack. This was followed by strict regulation of shade as per integrated pest management techniques. The percentage of damaged green fruits in the first year were 36 percent followed by 22 percent in the second year and 14 percent in the third year in treated plants against control 100%. Further, the mean grade index recorded at the time of harvest was also very low which statistically different from chemically treated plants. The other plant oil formulation viz., Pongamia and Iluppai were less effective and the leaf extract. Ipomea, Jatropha, Neem, Acorus and Chilli were not effective.
