Plant pathologists need to manage plant diseases at low incidence levels. This needs to be performed efficiently in terms of precision, cost and time because most plant infections spread rapidly to other plants. Adaptive cluster sampling with a data‐driven stopping rule ( ACS *) was proposed to control the final sample size and improve efficiency of the ordinary adaptive cluster sampling ( ACS ) when prior knowledge of population structure is not known. This study seeks to apply the ACS * design to plant diseases at various levels of clustering and incidences levels. Results from simulation study show that the ACS * is as efficient as the ordinary ACS design at low levels of disease incidence with highly clustered diseased plants and is an efficient design compared with simple random sampling ( SRS ) and ordinary ACS for some highly to less clustered diseased plants with moderate to higher levels of disease incidence.
