Neco 2025 Agricultural Science Question 6
Practice objective / multiple choice question 6 from the 2025 Neco Agricultural Science examination.
A farmer observed a disease incidence of 20% in a 5‑ha cassava field. After applying a fungicide at only 60% of the recommended rate, the incidence fell to 14%. Assuming disease reduction is directly proportional to the amount of fungicide applied, what would have been the expected incidence if the correct amount had been applied? Also, calculate the amount of money saved on fungicide if the recommended rate is 0.8 L per ha, the fungicide costs \(\text{₦}150\) per litre, and the farmer used only the 60% amount.
