Aug 25: Glyphosate

August 25:  fall weather/ 80’s and sunny but chilly morning/ a bit breezy

First-ever use of the new Chapin backpack sprayer.  It came in the mail last week and I’d assembled it and tested it using water before, but today was the first time it had roundup in it.  

    I sprayed two full 4-gallon pack fulls.  I mixed 8 ounces of roundup Quickpro.  I covered much of the Left Bank, especially in the areas surrounding the slash and stacks we had completed.  For the most part I did not spray any regrowth in these areas, since I’d like to wait til it gets a bit bigger and then spray.  I sprayed along the sand bed and down past the big fallen log.  Trying to keep it from spreading up the slope!  

I went through 8 gallons spraying in a couple hours.  This included prep and cleanup I believe.   i hit some poison ivy along the perimeter path as well, and I hit the fenced-in part of the field, where the PI is going crazy.  I’d love to get the path clear enough that I can walk it without having to worry about PI...

I wore khakis and long-sleeve shirt and baseball cap and mask.  Full face mask might be better.  ditto for covering full head and neck.  

Questions:

Was the concentration strong enough?

Did I clean the tank well enough?  I rinsed it out, then refilled and sprayed it for 30 pumps, drained it, refilled a gallon or so and sprayed for another 30 pumps.

How much overspray was there?  We’ll see, but I know there will be some other dead plantlife out there.  

How long should we keep Stanley away from the stuff?  Is 24 hours enough?

Would an injector be more effective?  How much slower though?

Next target:  along road and Right Bank (upper brook section). Also:  hitting the newgrowth on those sections we cut last month.
