Evaluation of Bamethrin 2.5EC Efficacy for Pests? Control in Flue Cured Tobacco

Magdalena R. | Donatha D. | Elimboto M.

Abstract: A two - year trial was conducted to test the efficacy of Bamethrin 2.5 EC (Deltamethrin) in flue cured tobacco (K.326) and recommend the appropriate dosage in tobacco production. The trial was on station at Tobacco Research Institute of Tanzania in Tabora region. A randomized complete block design (RCBD) was employed with three replications and five treatments. There were five treatments: 0.08liter/ha Bamethrin 2.5EC, 0.12 lts ha - 1 Bamethrin 2.5EC, 0.16liter/ha Bamethrin 2.5EC, 0.20 lts ha - 1 Bamethrin 2.5EC and control 2 ml/20 lts ha - 1 Amecron. NPK (10: 18: 24) basal fertilizer was applied followed by top dressing CAN (27% N) at the amount of 10 and 2.5 bags of NPK and CAN per hectare, respectively. Green and cured tobacco yields showed a significant difference between all treatments where in the first season 2011/12 Amecron had higher fresh and cured yield than other treatments followed by treatment number three (0.16ltha - 1) while the lowest yield was obtained from treatment number one (0.08l/ha). In the second season (2012/13) Treatment number three 0.16lts ha - 1 out yielded the control the lowest yield obtained from treatment number two 0.12 lts ha - 1). Few insect pests were observed in 2011/12 season compared to 2012/13 season where by in the first season few aphids and budworms were observed in the and whitefly observed in treatment number three. A larger number of aphids and budworms were observed from the control. From these findings, 0.08lha - 1 of Bamethrin EC is more efficient dose for controlling aphids, whitefly and budworm thus highly recommended in flue cured tobacco production.
