During the idle time, I figured I'd put up some videos of drone spraying.
Sure not gonna have drift problems with drone application
Apparently large swaths of Australia are covered in Blackberries.......................
Really not what I'd call a spot treatment, but I guess there's such a huge infestation that chemical going on, non infested, ground is considered a cost of the operation. It does solve the problem of getting chemical to the center of the thicket.
I've been very interested in the process, which has gotten around to seeing the investment these guys are making. Near as I can figure, the trailer alone costs somewhere in the range of 100K................not sure whether that includes the cost of the actual drones.
The bulk of the videos I'm seeing are promotions for drone sales...............................
NO WONDER
With the involved costs, I'm figuring "small" jobs will be priced accordingly. You're gonna pay time out, on site, and time back. These things cost money, and have to be paid for.
I'm not stopping work on the pull behind sprayer just yet.
Major SNAFU on Friday. I left the house too late to complete a circular drive from here, to Perry, to Tulsa. By the time I got to Tulsa.........Grainger had closed. I'd of made it except for a major road closure. Pine street was closed for almost a mile, making a 4 mile detour necessary. I got to Grainger 10 minutes after it closed. Drove back to Tulsa today to complete the parts purchases. OOOOOOMPH.
I'm thinking we're pushing the dormancy boundary. The days are getting short, which has a bigger influence than temperature on dormancy. We might have lost our window. Major rain event coming on Tuesday evening, lasting for 2 days. If the plants look refreshed, we might commit to spraying(shrug) If not, then it's time to start clearing trees, and doing cut stem (stump) treatments. Removing the trees will at least give us a hay crop next Summer.........even though the Blackberry treatments will have to wait till August/September.
Something I've been researching, is the difference between liquid herbicides, and free flowing powder/wettable powder herbicides. I might not have enough excess GPM capacity in the little PTO pump to spray the granular chemicals. The dry powders, in water, don't fully dissolve............and require very healthy tank agitation to stay in solution. I'm looking into whether surfactants can hold the powder in suspension.
The agitation problem is stemming from pump ratings. I picked up a pump "rated" at 300psi. BUT A CLOSE LOOK AT THE BOX, AND INSTRUCTIONS, SHOWS THAT 300psi IS INTERMITTENT psi. It's not rated for a constant 300psi output. Gotta love the sales/marketing guys. I need to get on the blower, and see what the duty cycle is for the max 300psi output.
This also relates to GPM output. A certain GPM has to be diverted to agitation..........leaving less GPM for actual spray application. This might be solved by the duty cycle thing I've talked about. Agitation time, spray time, agitation time. Put a clock on it. It's the po folks way of getting it done.
If we can't solve the problem, I guess we'll switch to Triclopyr. The liquid herbicides require less agitation. I can get generic Triclopyr relatively cheap........making higher concentration mixes doable.
I need to get ahold of a person who's actually done this, in the PROPER way. No wives tales, or local lore. And willing to share it. K'kins is putting feelers out. She knows more people than I do. I ain't a very friendly guy. But I'm friendly to folks I respect. It's something you'd have to experience to understand. There are people out there who's advice you can trust. Lord Knows I don't know WTF I'm doing
