Neco Model Questions Vol1 2022 Agricultural Science Question 7
Practice objective / multiple choice question 7 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
A certain crop pest causes a loss of \(0.5\) kg of maize per hectare for each insect present. The market price of maize is \(\$0.5\) per kilogram, and the cost of applying an insecticide is \(\$30\) per hectare. Using the economic threshold formula \(ET = \dfrac{C}{V \times D}\), where \(C\) is the control cost per hectare, \(V\) is the market price per kilogram, and \(D\) is the loss in kilograms per insect, calculate the threshold number of insects per hectare above which control is justified.
