Neco Model Questions Vol1 2024 Agricultural Science Question 22
Practice objective / multiple choice question 22 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
An insect pest causes a daily yield loss of 0.05 % of the expected harvest of 2 000 kg ha⁻¹. The market price of the crop is ₦200 per kg. A pesticide costs ₦1 500 ha⁻¹ to apply and kills 80 % of the pest population instantly. Using the economic injury level (EIL) formula \[EIL = \frac{C}{V \times I \times K},\] where \(C\) is control cost, \(V\) is market value per kg, \(I\) is injury per pest (kg loss), and \(K\) is the proportion killed, determine the minimum pest density (number of pests per hectare) at which pesticide application is justified. Round up to the nearest whole pest.
