Gce Model Questions Vol1 2019 Agricultural Science Question 26
Practice objective / multiple choice question 26 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A farmer monitors a pest population in a maize field. The economic injury level (EIL) is calculated using the formula \(EIL = \frac{C \times I}{V \times D \times K}\), where \(C\) is the cost of control per hectare (₦500), \(I\) is the loss in yield per pest per hectare (2 kg), \(V\) is the market value of the crop per kilogram (₦200), \(D\) is the damage per pest (0.6), and \(K\) is the proportion of the pest population that actually causes damage (0.4). The action threshold is set at 50 % of the EIL. Calculate the action threshold (number of pests per hectare) and give your answer rounded to the nearest whole pest.
