Abstract/ Executive Summary:

A comparative effectiveness of several granular insecticides were assessed in controlling rice stem borer in both local and high yielding IRRI varieties in the Bangladesh Agricultural University Farm. Sevidol, Ekalux and Niran 1.5, 2.0 & 2,5 kg (a.i./ha,) and Diazinon 2.0, 2.5 & 3,0 kg (a.i, /ha) were found effective in controlling stem borer and increasing the total yield of paddy in both Aus and Aman seasons. Results of Bidrin as granules were not promising.

Keywords: Comparative effectiveness, granular insecticides, rice stem borer

Location: Mymensingh

Start Date: 01-04-1969

End Date: 31-12-1969

Program Area: Pest Management

Commodity:

Objectives:

To see the effect of Diazinon, Ekalux, Niran and Bidrin(Organophosphorus compounds,Sevidol(Carbamate + Gamma BHC),Gammadol(Gamma -BHC)and, Thimet- BHC(Phorate-+ Gamma BHC) in controlling rice stem borer

Methodology:

Experiments were conducted on transplanted IR6-156-3-3 as Aus and Aman, Dacca 2 (Kataktara-Aus) and Dacca 17 (Latishail-Aman) varieties from April to December, 1969 under controlled irrigation in the Bangladesh Agricultural University Farm. Completely randomized designs were followed in both seasons. The layout of the experiments included 40 plots having an area of 0.2025 hectare (Plot size: 9 x 4.5 meters). Each plot was divided into two equal parts and two varieties of rice were transplanted in each half.

Achievement/Findings:

The overall performance of IRRI variety was not very encouraging in Aman season, even the same cultural as well as other practices were uniform in both Aus and Aman seasons. This might have resulted from the reactions of the IRRI variety to the seasonal changes.
