It is estimated that 20-30 % of farm produce is damaged annually due to insect attack. Borers in particular are a major threat to fruits and plantation crops causing huge reduction in yield and subsequently leads to death of the mature and bearing plant. These are a group of insects that spend part of their adult or larval life stage feeding inside roots and branches or tunnelling beneath the bark or into the heartwood of many trees and shrubs. Tunnelling cuts off the water supply and can cause foliage to be off coloured or drop prematurely, cracking of the bark and dieback of branches and twigs. Injury caused by the borers can be long lasting and moderate to heavy infestation can cause death of the plant.
An early detection of the borers can reduce the crop loss. Many attempts has been made by the scientific community as well as farmers. One of such innovative technique is developed by Mr. Chakradhar Pradhan, earning him the sobriquet “Gachhara daktar” ( Doctor of plants) in his locality. He hails from Jahnapada village in Attabira block of Bargarh. Owing to economic trouble he had to drop out from school at 13 just after completing his seventh standard. He started supporting his father in agriculture work but he never let go of his dream. At the outset he developed a passion for agriculture and always wanted to excel in is field. His passion and enthusiasm led him to start a lemon orchard on over 30 decimals of land in 1983.Much to surprise of the fellow villagers his orchard was spread over 5 acres within no time and he became a successful farmer.
To his dismay once ¾th of lemon plants started drying up and died in quick succession, leaving him devastated. Local expert in agriculture failed to find out a convincing reason. In the meantime Dr. Manoranjan Sahu, MBBS paid a visit to his orchard. He was having a stethoscope with him and that created an out of box idea to the curious mind of Mr. Chakradhar Pradhan. He thought it would be great if he can find the pest in the trees using a stethoscope.
Surprised and amused with his idea Dr. Sahu gifted it to him and left. That day changed his life and rest is history. He started an expedition to discover something new by listening to the pulse of plant life. On examining dead plants with the stethoscope he could hear the sound of cutting which he could not hear in a healthy plant. Based on the observation he dug up the soil beneath the roots and found out insect of about 3c.m.
Excited at having discovered a cause he later came to know that the insect was root borer and it had indeed killed the plant. This identification of cause helped him to use necessary pesticide and eventually he was able to save his orchard. Initially his experiment was confined to lemon trees but later on he extended it to other plantation crops also.
This success came at cost of many struggle. Initially the villagers called him mad when they found him sitting underneath the dead lemon trees with a stethoscope to his ear. But he was adamant in his endeavour to succeed and years later his efforts were being recognised. His novel approach has been widely appreciated and has earned him many accolades. His work was documented by National Innovation Foundation(Autonomous Body of Department of Science and Technology, Government of India). Subsequently an American organisation “trees for life” had appreciated his technique and felicitated him. What began as a moment of inspiration followed by ridicule is now a novel idea for early detection of the borers.

His concept can be applied to all most all perennial fruit trees such as coconut, arecanut and different species of palm and different temperate fruit trees such as Apple, Pear ,Peaches and plums which are prone with different shoot and root borer insects. This early detection of insects save the tree from death and helps the farmers to use different insecticides to save the plan
By using stethoscope we can detect Red Palm Weevil (Ryncophorus ferrugienus) in all palm species like Coconut, Arecanut etc and helps in preventing the damage and death of the mature bearing plant’s and save the crop.
Although his innovation of early detection of root and shoot borer insects using Stethoscope is already being recognised by ICAR(INDIAN COUNCIL OF AGRICULTURAL RESEARCH) and patented by National Innovation Foundation(Autonomous Body of Department of Science and Technology, Government of India) on his name ,there is a lot of scope for further research in this area. He recommends that “Just like the medical science students are given stethoscope to measure the rate of hear beat and detects any health problems , agricultural science students should also use stethoscope to detect shoot and root borer insect in fruit and plantation crops.”
The students who are doing their research in the field of entomology; his method provides a great scope for further research of his concept of early detection by hearing the borer action sound in different fruits, vegetables, ornamental and plantation crops which are mostly affected by root and shoot borer insects. He is very kind enough to transfer his technology to the farmers and students who wish to contact him in this regard.We hope that his research in this early detection of root and shoot borer insects using stethoscope will help farmers across the world to detect the insects at early stage and save the plant from the damage and commercial loss it causes to the farmers.
