Abstract/ Executive Summary:

An experiment was conducted at RSRS farm, Gazipur to screen out advanced clones for possible resistant to stem borer in sugarcane field. From the experimental results revealed that, the number of infested cane was highest (31.87%) in Co 208 variety which significantly differed from other treatments. It was indicated that Co 208 variety was highly susceptible to stem borer. Infested cane height was found lower in infested cane than the non infested cane in all varieties. The variety Misridana showed highest length of 2.88 meter which significantly deferred from Co 208 and C0 527 but identical with Amrita, Q 69 and Isd 24. Misridana gave highest individual cane weight of 1.73 kg that was significantly difference from others. Similar trend was found in cane girth and Brix%.

Keywords: Chewing cane, Varieties and Stem borer

Location: RSRS farm, Gazipur

Start Date: 21-01-2009

End Date: 02-02-2010

Program Area: Pest Management

Commodity: Insects

Objectives:

1. Screening out advanced clones for possible resistant to stem borer.

2. To compare resistance among the selected varieties/clones.

Methodology:

The experiment was set up in RSRS farm, Gazipur during the cropping season 2008-09. Six chewing sugarcane clones namely Amrita, Co 527, Co 208, Q 69, Misridana and Isd 24 (Standard) were included for screen out. Clones were transplanted following RCB design with replicated three times. Two eyed setts were transplanted and recommended fertilizers 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:

Use of resistant variety for controlling insect pest is an environment friendly technology. From this experiment we got some findings regarding the pest reaction of different chewing clones. Cultivation of resistant variety may reduce the cost of production and use as a component of IPM. Also this research will be informative for breeders. The findings of this experiment may help to reduce indiscriminate use of chemical insecticide. It is a fundamental study to identify the resistant chewing clones which is a component of IPM package. The farmers can use resistant variety for controlling insect pest.
