Neco Model Questions Vol1 2025 Agricultural Science Question 10
Practice objective / multiple choice question 10 from the 2025 Neco Model Questions Vol1 Agricultural Science examination.
A tomato farmer monitors the leafminer pest. The economic injury level (EIL) is given by \(EIL = \dfrac{C}{V \times I \times D}\), where \(C\) is the cost of control per hectare (₦1500), \(V\) is the market value per kilogram of tomatoes (₦200), \(I\) is the injury per pest (0.02 kg loss per leafminer per hectare), and \(D\) is the damage factor (0.5). The farmer counts an average of 8 leafminers per plant. The field density is 25 plants per m\(^2\) and the farm size is 1 ha (10,000 m\(^2\)). Determine whether the current pest density exceeds the economic threshold and state the appropriate action (apply control or no control).
