Presently, there is a willing to reduce the chemicals and not using the systematic chemical control especially in organic farming. Using of heat treatment method to eliminate the pathogen is an old method but there was no devices to address the needs of those attempting to control of pathogen effectively. The present invention is comprising but not limited to structural design, heating system, system to reduce transpiration, system and method to maintain the uniformity of temperature and humidity, method/s to control the heat transfer rate into trees tissue and system to maintain the heat transfer duration, more particularly, the present invention is toIncrease the uniformity and faster penetration into tree canopy middleReduce the energy consumption by targeting the tree canopyReduce the time of operation and increase the quality of the treatmentReduce the risk of operation due to increase the uniformity and also, by providing variable rate heat transfer to the tree as per requirementOptionally, by attaching the roots heat treatment machine to the tree heat treatment apparatus, all the canopy will be covered in one pass.
