Neco Model Questions Vol1 2018 Agricultural Science Question 33
Practice objective / multiple choice question 33 from the 2018 Neco Model Questions Vol1 Agricultural Science examination.
A tomato farmer observes a whitefly population of 5 insects per plant. Each whitefly causes a loss of 0.02 kg of marketable fruit per plant. The market price of tomatoes is ₦150 per kg. The cost of applying an insecticide is ₦12 000 per hectare, and one application protects 1 000 plants per hectare. The field contains 10 000 plants per hectare. The insecticide kills 90 % of the whitefly population (K = 0.9). Using the economic injury level formula \(EIL = \frac{C}{V \times D \times K}\), where \(C\) is the cost of control per hectare, \(V\) is the market value per kg, and \(D\) is the loss in kg per insect per plant, calculate the EIL in insects per plant and decide whether the farmer should spray.
