Economic thresholds are developed by researchers to let farmers know when to invest in managing an insect, disease or pest to keep it from reaching an economic injury level (EIL). The EIL is when the crop value lost to injury exceeds the cost of treatment.
Using thresholds are an important tool for farmers in knowing when to take action against a yield-limiting problem, when treatments are worth it to use and when they are not. Of course, the best way to determine if the scope of the problem warrants the cost of treatment is to scout thoroughly and regularly.
