Agrowing works with vetorgeo to enable UAVs to detect citrus trees infected with HLB or citrus virescence disease. UAVs can detect disease symptoms from above by using multispectral sensors.

Using UAV technology to locate infected trees and crops

The work of the two companies is a huge breakthrough in this field, because it has surpassed the biggest challenge in detecting the disease.


Dr Kelly pazolini, a researcher at vetorgeo, said: “up to now, there is no effective NDVI to detect HLB, which is why the sensor developed by agrowing can bring so much subversion to the citrus industry. It is crucial to find new symptoms in order to remove infected trees as soon as possible. This allows them to be replaced and limits the damage they do to the rest of the orchard


It usually takes six months to two years for citrus trees infected with this disease to begin to show symptoms, causing a lot of irreparable losses. UAVs that use artificial intelligence to check tree symptoms can usually locate infected trees as early as six months to two years.

Huanglongbing (HLB) is one of the most destructive diseases of citrus trees in the world. It is caused by non culturable coniferous restrictive bacteria. It spreads from one tree to another through the canopy, eventually killing any infected tree. There is no cure for it.


AI programs are developed by providing AI with images of infection trees. After hundreds or even thousands of times, AI now knows what to look for. The more images you provide to AI, the more accurate it will be.


Agrowing is currently creating an easy-to-use tool that will allow service providers to select the right plant or crop algorithm, launch drones and return results. It hopes to be able to do this for a variety of plants and crops, which will enable service providers and farmers to quickly and easily check their crops for any problems
