Practice objective / multiple choice question 27 from the 2018 Neco Agricultural Science examination.
A certain insect pest causes a loss of 0.02\,kg of grain per hectare for every 100 insects present. The market price of the grain is \(\text{₦}150\) per kilogram and the cost of applying a control measure is \(\text{₦}600\) per hectare. Using the economic injury level formula \(EIL = \frac{C}{V\times D}\), where \(C\) is control cost, \(V\) is grain value per kilogram and \(D\) is loss per insect per hectare, determine the number of insects per hectare above which control should be applied.
