Abstract

The extract of Nicotiana tabacum L. var Virginia origin of Ponorogo (EHRE-Nt) was applied under field conditions against the coffee borer beetle Hypothenemus hampei (CBB). ,ree extract formulations containing 150, 300, and 450 ml of EHRE-Nt in 100 liters of water were prepared and sprayed on 0.5 hectares each. A nontreatment was applied as a control on 0.5 hectares of plantation. ,e intensity of the CBB attacks was observed for six weeks on a Robusta coffee plantation in the Kalibening area, South Semarang, Central Java, Indonesia. An extract formulation containing 450 ml of EHRE-Nt resulted in the lowest intensity of CBB attacks from weeks one to six (1.6% to 2.2%). ,e attacks of the control field were 11.3% to 13.5%. ,e highest efficacy level of 85.4% was obtained with the 450 ml EHRE-Nt formulation. ,ese results demonstrate that EHRE-Nt has potential as a bioinsecticide for coffee berries from CBB attacks.
