In “Indicator and date” column, “DLP” represents damaged leaf percentage, the number before “-” indicates the test serial and the number after”-” indicates the days after artificial infestation, for example, “DLP1-3” represents DLP after 3 days of infestation in Test 1; those in italics represent the best date for evaluation
