In a maize field, the average stem borer infestation is \(3\) larvae per plant. The economic injury level (EIL) is \(2\) larvae per plant, and each larva causes a \(0.5\%\) reduction in yield. The expected yield without pest damage is \(8\) tonnes per hectare. Compute the expected percentage yield loss and the corresponding loss in tonnes per hectare, and state whether control measures are justified if they are recommended only when the expected loss exceeds \(5\%\) of the yield.

Answer Options

Correct Answer A. Expected loss is 1.5% (0.12 tonnes per ha); control measures are not justified
B. Expected loss is 1.5% (0.12 tonnes per ha); control measures are justified
C. Expected loss is 2.0% (0.16 tonnes per ha); control measures are not justified
D. Expected loss is 0.5% (0.04 tonnes per ha); control measures are not justified
