Chapter 13: Problem 8

Define the term economic threshold as it relates to pest control. What are cosmetic spraying and insurance spraying?

Short Answer

Expert verified

Economic threshold in pest control refers to the level of pest presence at which it is economically justified to start pest control measures. Cosmetic spraying is a type of pest control measure that is carried out for aesthetic reasons rather than to prevent financial losses, while insurance spraying refers to pre-emptive actions taken as a precaution, even if pest numbers have not reached the economic threshold.

Step by step solution

Defining Economic Threshold

Economic threshold in pest control is a term used to describe the critical point at which the financial loss caused by a pest equals the cost of managing that pest. In other words, it is economically justified to start pest control measures when the population of the pest reaches the economic threshold level. In a graphical representation, this is the point where the cost line and pest damage line intersect.

Defining Cosmetic Spraying

Cosmetic spraying is the application of pest control measures, not necessarily due to the economic threshold being reached, but rather for aesthetic reasons. This means that the pest control is done to maintain the appearance of the crops or plants, rather than to prevent financial losses. It is a form of spray that gives a visual appeal to the farm or the garden but is not economically justified.

Defining Insurance Spraying

Insurance spraying is a type of preemptive pest control action. In this case, pest management is carried out as a precautionary measure, even if the pest numbers haven't reached the economic threshold. The spraying is used as 'insurance' against potential future pest infestations. It's a risk management strategy taken to avoid potential future losses.
