Answer:- 4. Plant Protection

Explanation:- ETL (Economic Threshold Level) is an important concept in integrated pest management and plant protection.

What is Economic Threshold Level (ETL)?
 
“ETL helps initiate control measures before pests reach the Economic Injury Level (EIL), preventing significant crop damage and yield losses.

 
ETL vs. EIL (Key Exam Distinction)
Agricultural entrance and officer exams frequently test the difference between these two metrics:
  • ETL (Economic Threshold Level): The “action threshold.” You apply pesticides or biocontrols here to keep the pest population from growing out of hand.
  • EIL (Economic Injury Level): The lowest pest population density that will cause actual economic damage. The cost of crop damage at this point equals the cost of managing the pests. ETL is always kept lower than EIL so farmers have a safety margin to respond before losing profits.
