Italy’s olive crisis intensifies as deadly tree disease spreads

Are there any sensors you can use to monitor health of trees programmatically?

"These plant defenses do not seem to hinder the movement of X. fastidiosa. Occlusion of vascular tissue, while a normal plant response to infection, makes symptoms significantly worse: as the bacteria itself also reduces vascular function, a 90% reduction of vascular hydraulic function was seen in susceptible Vitis vinifera."

Some type of low energy Bluetooth moisture sensors or a sensor you can stick in the tree itself to monitor reduction in "vascular hydraulic function? of it's xylem tissue?

That wouldn't scale because of the range and topology of BLE. Solar-powered micropower 900 MHz modules with built-in microcontrollers would be a basis for a viable solution. 900 MHz carries much further for a given power and isn't as susceptible to attenuation due to foilage.

Source: did industrial 900 MHz and 2.4 GHz module testing, once upon a time.
