Islam 4200324The performance of Ronster 25EC, Setoff 20WG and Golteer 5G at different rates as herbicide in comparison to each other in BR-11 variety of aman rice was investigated. Twelve weeds species belonging to seven families were found to grow and infest the experimental crops of which Angta, Panikachu, Matichaisa and Joina were dominant in respect of population density. Ronstar 25EC @ 1.0 l ha-1 was most effective in controlling weeds (64.21%). However, the epicacy of Ronstar25EC at the rate of 2.0 l ha-1 was more or less identical (62.44%) with that of Ronstar 25EC @ 1.0 l ha-1.]]>Anonymous,1997pp: 127-129pp: 127-129Anonymous,19911991Burhan, H.D., Sozzi and A.
