Gce Model Questions Vol1 2017 Agricultural Science Question 46
Practice objective / multiple choice question 46 from the 2017 Gce Model Questions Vol1 Agricultural Science examination.
A maize farmer considers using a pesticide that costs ₦500 per hectare. The market price of maize is ₦12 per kilogram. Each pest individual causes a loss of 0.02 kg of maize per hectare. The pesticide kills 80 % of the pests present. Using the economic injury level formula \( \text{EIL}=\dfrac{C}{V\times I\times K} \), where \(C\) is the control cost, \(V\) the market value per kilogram, \(I\) the loss per pest (kg), and \(K\) the proportion of pests killed, calculate the pest density (number of pests per hectare) at which control becomes economically justified. Round your answer to the nearest whole pest.
