Abstract
A field experiment was conducted Agronomy Divisions field Laboratory of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh under wet land condition during January to May 2019 to determine the efficiency of different classes of herbicide. There is scarcely works on determination of efficiency of available 15 classes of herbicide in Bangladesh. The objectives was to know the efficiency of herbicide in suppressing the flora of weeds species and family, analysis of crop growth parameters and yield of boro rice. The experiments were laid out in a randomized complete block design (RCBD) with three replications and 20 treatments. In this experiment highest weed control efficiency was found at penoxsulam 86.55% which is followed by (bensulfuron methyl + acetachlor), 84.25% and lowest glyphosate 54.62% treated plot. The chemical classes (bensulfuron methyl + acetachlor, pretilachlor, pyrazosulfuron ethyl, ethoxysulfuron, bispyriback sodium, bensulfuron methyl + bispyriback sodium, penoxsulam, pyrazosulfuron ethyl + pretilachlor) WCE % more than 80. Seventeen weed species belongs to six families namely Gramineae, Pontederiaceae, Cyperaceae, Asteraceae, Marsileaceae and Sphenocleaceae were found to grow in weedy check plots. The highest summed dominance ration of weed was 10.5for Cyperus difformis. The infestation of different categories weed maximum relative weed density was observed for Echinochloa colona, Cyperus difformis, Leersia hexandra L. The highest grain yield (6.83 t ha-1) was found with penoxsulam treatment which was followed by (6.82 t ha-1) at Bensulfuran methyl+ Bispyriback sodium treatment and lowest (4.61 t ha-1) at control. This results indicates that boro rice could be grown with uses of efficient herbicides classes (bensulfuron methyl + acetachlor, pretilachlor, pyrazosulfuron ethyl, ethoxysulfuron, bispyriback sodium, bensulfuron methyl + bispyriback sodium, penoxsulam, pyrazosulfuron ethyl + pretilachlor) to maximize yield of boro rice.
