Question
The amount of basalin 45 EC for a plot of 50 m x 40 m
at recommended rate of fluchloralin at 0.75 kg/ha isSolution
Amount of basalin (kg/ha)= Rate of application/ ai in herbicide (%)×100                                                                    = 0.75/45×100=1.66kg/ha For 10,000 m2, basalin require will be= 1.66 kg For a plot of 50m×40 m, basalin required will be 1.66×2000/10,000=0.333kg Â
