      Minirhizotron is an effective below-ground camera system designed to study plant root growth and calculate the dynamic of root change year round without damaging the plant. Past method involved digging down through the entire length of the roots which is time-consuming and labor-intensive but damaging the plant. For this reason, Minirhizotron is now popularly adopted for study of physiology of plants as well as a plague like white root disease caused by Rigidoporus microporus which is widerspread in the southern of Thailand.

Thus, came the development of equipment to facilitate the research of Tregio similar equipment had been purchased from abroad hence expensive. Minirhizotron has been tested with rubber trees, oil palms, salaccas, coffee trees, and wild trees and proven to be effective for fieldworkThe camera has thus since been used to study other economic plants such as sugar cane, cassava, and riceBecause it can also study roots in flooded soil to observe the direction of root growth, Minirhizotron can also facilitate study of roots in shifting climate and thus provide guidance on how to better care for the plants in such conditionBased on aforementioned high performance, it is clear that Minirhizotron could be developed commercially to replace expensive the exported counterpart.
