Neco Model Questions Vol1 2024 Agricultural Science Question 8
Practice objective / multiple choice question 8 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
In a tomato field the economic injury level (EIL) for whitefly is given by \(\text{EIL}=\dfrac{C}{V\times I\times D}\), where \(C\) is the cost of control per hectare, \(V\) is the market value per kilogram of tomato, \(I\) is the injury per whitefly (kg loss per whitefly per hectare) and \(D\) is the efficacy of the pesticide (proportion killed). The farmer can apply a pesticide that costs \(\text{₦}12,000\) per hectare and kills 80\% of the whitefly population. Tomato sells for \(\text{₦}150\) per kg and each whitefly causes a loss of \(0.02\) kg per hectare. The current whitefly density is 5,000 insects per hectare. Should the farmer apply the pesticide?
