Question
 What will be the weed control efficiency (%). if the
number of weeds in clodinafop treated plot is 190/ m² and that in a control plot is 361/m²?Solution
Weed control efficiency= Weed population in control plots- (weed population in treated plots) / (Weed population in control plots) × 100 = 361-190/361×100 = 47.3
