Gce Model Questions Vol1 2019 Agricultural Science Question 14
Practice objective / multiple choice question 14 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A 3 ha maize field is surveyed and an average of 8 fall‑armyworm larvae are found per 10 m². The economic injury level (EIL) is 5 larvae per 10 m². The recommended pesticide is applied at 2.5 L ha⁻¹ and contains 0.8 % active ingredient (a.i.). Each litre of product contains 8 g a.i. and reduces the larval density by 1.5 larvae per 10 m² uniformly across the field. Assuming the farmer wants to bring the population just below the EIL, calculate the total volume of pesticide (in litres) that should be applied to the whole field.
