A 5‑ha field is affected by a fungal disease that reduces the yield of infected plants by 30 %. A survey shows that 40 % of the plants are infected. The baseline yield is 3 t ha⁻¹ and the market price is \(\text{\u00A3}100\) per kg. A fungicide costing \(\text{\u00A3}5{,}000\) ha⁻¹ reduces the incidence of infection by 75 %. Should the farmer apply the fungicide? Show the net profit per hectare with and without the treatment.

Answer Options

A. Yes, apply the fungicide; net profit becomes \(\text{\u00A3}286{,}000\) ha⁻¹ versus \(\text{\u00A3}264{,}000\) ha⁻¹ without it, a loss of \(\text{\u00A3}22{,}000\) per hectare.
Correct Answer B. Yes, apply the fungicide; net profit becomes \(\text{\u00A3}286{,}000\) ha⁻¹ versus \(\text{\u00A3}264{,}000\) ha⁻¹ without it, a gain of \(\text{\u00A3}22{,}000\) per hectare.
C. No, do not apply the fungicide; net profit is \(\text{\u00A3}286{,}000\) ha⁻¹ versus \(\text{\u00A3}264{,}000\) ha⁻¹ without it, a gain of \(\text{\u00A3}22{,}000\) per hectare.
D. Yes, apply the fungicide; net profit becomes \(\text{\u00A3}280{,}000\) ha⁻¹ versus \(\text{\u00A3}260{,}000\) ha⁻¹ without it, a gain of \(\text{\u00A3}20{,}000\) per hectare.
