​Well...ok...the drones are not ‘killing’ the pollination business just yet. But, since my last post on drone pollination, I’ve found some other alternative pollinators that are trying to find a place in the pollination market. Perhaps these drones will help alleviate bee supply issues some growers are facing.


Poli-X2 drone

In North Carolina, Thomas Parish IV and his team have built the Poli-X2 drone, which pollinates more similarly to bees (unlike the Pollinator Bot, referenced in my previous blog post). The Poli-X2 has been testing in local gardens since 2017. One of the biggest challenges they faced in developing their model was inhibiting the device from lurching forward when flying in for flower pollination. From what I can see in the video footage, it looks like they’ve done a pretty good job with this.

Their model is not designed to replace bees, but to supplement the pollination done by existing bees. The drone uses artificial intelligence to scan for pre-programmed species of flowers, including tree flowers. At this time, the images being collected from the device are being sent via WiFi to a nearby PC where decisions are made regarding which plants to pollinate. Later development plans are to install this decision-making software within the device... that’s what we call edge computing, good ol' IoT (internet of things).


Plan Bee drone

The Bee Corp is headed to the Forbes AgTech Summit next month in Indianapolis, and fellow attendee and panelist Anna Haldewang has been working on her own pollination drone, Plan Bee, which she first devised for a product design course at the Savannah College of Art & Design in Georgia.

​The drone is controlled by a smart device and has six sections on its underside that suck pollen from the flowers it hovers over. The pollen is later expelled for cross-pollination. It’s innovative…and, yes, I’m going to say’s so darn cute! Art and Engineering combined!


Dropcopter drone

Now, there are other ways of getting flowering crops pollinated... such as literally dropping a whole mess of pollen from the sky. Dropcopter, the aptly-named startup with offices in New York & San Francisco, has developed a drone to do just that. Some test results show that the Dropcopter drones can increase "pollination rates" between 25-60% in almonds & cherries, depending on weather conditions.

​It's unclear how they measure pollination rate—perhaps it's the number of times each flower is visited by bees? Regardless, I applaud this no-frills approach.


Bu​t if you want to get REALLY heavy-handed with the pollination, you can give the guys from Pollen-Tech a call. This Arizona-based AgTech startup doesn’t use drones in its operation, but an electrostatic spray technology to mist almond trees during pollination season. Initial field test results showed a 6.55% increase in crop yield over untreated control-group trees. The electrostatic charge helps the pollen become attracted to the stigma of the flowers, increasing the efficiency of the process, without significant pollen loss.

It’s great to see all of these technological innovations in the works. For the near future, these methods are only equipped to supplement what the busy bees are doing in their pollination efforts. And they could help give growers some peace of mind when aren’t able to book the bevy of bees they need to get their crops pollinated. Exciting times for AgTech!
