Hi Contact,
I hope all is well with you!
Hi Van,
I can't begin to count all the 'why?s' I've followed your creation as long as it's been on the webs, please don't subject that fine machine to a life of caustic corrosive smelly showers. Your post is really open ended, so I will not draw conclusions past that little comment.
Hi gb... yes, you set the bait... and yes you are correct. There really is no debate as to who what gets better coverage, but you are mistaken if you just plaster 'ground rig' as the answer.
Best coverage award (or more appropriately, best application award) goes to the applicator
applying the best, irregardless of his tool of application PERIOD. All
any of us are doing is covering the plant with appropriately sized droplets for the task at hand.
The
only thing a ground rig is better at is forgiving slobs. Anything can and will drift, anything can and will streak, anything can and will allow volatile chemicals to move.
For anyone that thinks I am biased, I'm OK with that, I'm not buying or selling anything to you, and have little to prove to the growers I spray for that actually own their own ground rigs. They have already connected those dots.
Which brings me to another point... spray? who started this? We don't spray anything.... If you suspend an airplane from a gantry and run the pump, you'll find that we 'spray' about 2 feet... and no one but Contact is flying loaded spray plane at 2 feet above the canopy today with todays chemicals, and actually getting a good result (sorry Jim, just funnin') We are spraying droplets in the air / wind, which in turn is depositing those droplets where we want them. A good applicator will have learned how to use mother nature (his real paint brush) and put those droplets exactly where he wants. I will admit, spray plane sounds a lot cooler than droplet plane
I used to get a note on my rec.'s from a particular grower that would say 'Please use back and fourth pattern with narrow swath
so as to hit both sides of the plant' There is not enough magic in the world to do this with any spray plane or helicopter. Even a ground rig at 20" off the canopy can't rely on this... The wind is always going to deposit it on the down wind side.
There will always be people and regions that favor one method or another, and that is cool, but science is science, and in this case it's really pretty clear if a person is willing to look.
As to the age thing? I have nothing for you... I cringe at the kids that haven't got the stupid out of their system yet, strapping in to a single seat go fast with 5000 pounds of poison straddled between 2000 pounds of fuel....

but the thought of someone sneaking a peek under their cheaters to see if their depends are leaking isn't much more comforting....
Take care, Rob
A1, you're in prime snowbird country, and many of your neighbors winter in our backyard. Look us up if you're ever down this way, it would be fun to compare notes.
