It is crucial to observe that pink root can be challenge to totally extinguish , specially if it is already established in the land . Therefore , a compounding of preventive measure and direction strategies should be adopt to minimize its impact and protect onion crops .

In my own experience as a horticulture and landscaping expert , I have interpret case where pink root has caused significant damage to Allium cepa crop . It is a frustrating and dishearten situation for growers , as it can undermine their efforts and hard work .
