Researchers from the University of Georgia revealed in the third week of January 2013 that they were creating the technology which helps in identifying the plants that are in pain. The technology or the sensors were being worked upon.
These sensors detect the compounds called green leaf volatiles, which are emitted by the diseased plants into the devices which would be field-ready.
This technology will be useful for the farmers because it could lower the use of the pesticides and save a lot of money.
Green leaf volatiles are actually invisible to the human eyes. These compounds are also odourless and they are released by the plants much before the signs of any harm. The use of this technology could help in detecting the problems of the plants early, thereby reducing the disease transmission or crop loss.
This technology can be used in the grid pattern to the quarantine pathogens in a sector of the field, eventually reducing and localising the use of crop treatment. The technology will also be useful for catching the unhealthy vegetables and fruits. The research will soon enter the testing phase.
