Long post warning.
One of the best research data days I’ve been to on the last day of the spray drone conference. Had ag industry researchers on adjuvants, drift, deposition, and plant uptake from multiple countries with decades of experience. Here’s our main key takeaways in our opinion. A lot to unpack.
1. Reduce your tested coverage swath by 20-25% depending on canopy you are trying to pe*****te. Ex. The T50 seemed to run well at 30ft wide and 12ft above string test. We ran 24ft all last year which is 20% more narrow. Refreshing to see a numerical value to what we were already on track for and the industry trying to correct bad application.
2. 10-12ft above crop still seems to be the sweet spot.
3. 1 gpa work seems to be very inconsistent from Brazils data. It’s also illegal in the US. 2-3gpa is far superior. Just an observation.
4. Auburn had one of the most in-depth studies on fungicide I’ve ever seen. They also had a great study on 3gpa soybean desiccation vs 15gpa with a ground rig. Did not see a measurable difference in effectiveness using gramoxone. Measured the deposition and the actual uptake of the active ingredients of Delaro Complete on the ear leaf comparing drones and planes at 2 and 3 gpa. They physically pulled ear leaves (a ton of them, I’d hate to be doing that) 4-5 hours after application and had each one tissue tested. 2 gpa from drones had at or more than double the uptake than 2 gpa from a plane, that difference was cut in half with a plane at 3gpa. Same story with dye deposition on the ear leaf.
While there is way more research to be done and this is just one season, I was not expecting to see that big of a difference in uptake and deposition on the ear leaf. Would like to see helicopters and ground sprayers in this also. With 40 gallon drones hitting the field this year for testing and 60 gallon drones in development for a potential 2027 debut, 150ac an hour with one drone are on the horizon, pair that with proper application and you have yourself a superior aerial application platform.
We will be at 100-125ac an hour with two 20 gallon drones.
This was just a quick generalization, Im sure this research will be available online here soon and will post a link.
Give us a shout to get lined up for 2026.n
