Abstract/ Executive Summary:

An experiment was conducted at RSRS farm, Gazipur to observe the efficacy of detrashing in controlling sugarcane stem borer in sugarcane field. From the experimental results revealed that, the number of infested cane was highest in control treatment with 23.44% which significantly differed from other treatments. It was indicated that detrashing reduces the infestation of stem borer. Infested cane height was found lower in control that was not differed statistically with the treatment detrashing at 20 days but differed with remaining treatments. So stem borer reduced the cane height. In case of non infested cane height there was no significant difference among the treatments. The lowest individual cane weight was found in both infested and non infested cane. Girth of cane of non infested cane was higher than the infested cane in every treatment. Similar trend was found in Brix%.

Keywords: Sugarcane, Stem borer, Detrashing

Location: RSRS farm, Gazipur

Start Date: 19-01-2009

End Date: 2912-2009

Program Area: Pest Management

Commodity: Insects

Objectives:

1. Observation of the efficacy of detrashing in controlling sugarcane stem borer.

2. Estimating the effect of detrashing on yield of cane.

Methodology:

The experiment was set up in RSRS farm, Gazipur district during the cropping season 2008-09. Chewing sugarcane clones Amrita was transplanted following RCB design with replicated three times. Two eyed setts were transplanted and recommended fertilizers, chemical insecticides were applied with appropriate intercultural operations. After cutting the setts, these were dipped in 1% Bavistin 50 WP solution for 30 minutes. Then the setts were placed in soil bed and covered with straw for germination. All the varieties were transplanted in 8m x 6m size plot with 102 settlings in every plot. Settlings to settlings distance was 0.5 meter and line to line 1 meter. The cane was harvested at December 2009. Data on infested cane, cane height, individual cane weight, girth and Brix % were taken and analyzed with DMRT.

Achievement/Findings:

Farmers could be easily practiced this method. It helps to reduce the unnecessary actions and expenses. Control measures are taken on need basis when it necessary. Also it may help to reduce the indiscriminate use of chemical insecticide. The utilization of this technology may reduce the use of chemical insecticides, safeguard the environment. It will be a cheaper and environment friendly technology that will helpful for the farmer.
