Test it again with water but with 1000sqft instead of 250sqft. I think 250 is too small for you to get the consistent walking pace. Use the 1100 area.

 

The 1100 sq feet is a fenced-in back yard with a pool, so I may not be able to get a consistent walking pace back there either. I marked out the 250 sq foot on the road outside my house and tested there. I can extend it probably too 500sq feet. It's 10 X 25ft right now. I'll extend it to 10 X 50ft and try again.

 

OK, so I'm back again. This time I marked out 500sq feet and repeated the test with my new TeeJet nozzles!. This time, I covered the the 500sq feet in ~2 minutes.

Spraying into a measuring jug, in those 2 minutes, I got ~60oz. The TeeJet nozzles seem to have made a bit of a difference to the amount of water sprayed.

So by my maths, that would make 1000 sq ft in about 4 minutes, at almost a gallon per 1000sq ft. Does that sound a bit better @g-man?

So that would make the calculations for the carrier (water) a bit difference:

Area 1: 1300 sq ft = 166 oz
Area 2: 825 sq ft = 102 oz
Area 3: 1100 sq ft = 140 oz

The tenacity rate wouldn't change, as that's based off the plot size, correct?

 

The quantity of tenacity is purely based on rate and sqft to treat.

 

Right, the amount of water has changed, but the sq footage hasn't. So my tenacity calculations based on your spreadsheet and the size(s) of my 3 areas would remain the same at the 2 oz/acre rate.

Which were/are:

Area 1: 1300 sq ft = 0.358 tsp (1.765 ml)
Area 2: 825 sq ft = 0.227 tsp (1.119 ml)
Area 3: 1100 sq ft = 0.303 tsp (1.494 ml)

Thanks!
