Hi Everyone,
I'm hoping for a little bit of a sanity check on my math as this will be my first time spraying. I hope below I'm providing enough information and showing that I did my homework and am putting forward an honest attempt.
Essentially I'm looking to spray IPCO 2,4-D Ester 700 herbicide on a 2-acre pasture using a Fimco ATV-25-700-QR sprayer.
Based on the application manual for IPCO 2,4-d Ester 700 on pasture grasses it is recommending 'up to 3.4 L/ha in 100-300 litres of water per hectare'. The FIMCO manual for the sprayer does a great job in doing the math for me and telling me the pressure (psi), speed and the corresponding gallons per acre.
So I don't want to put the maximum amount of chemical down, but I wish it just gave me a value and not an 'up to 3.4L/ha'. I'm randomly thinking of using 2.5L/ha since its somewhere in the middle of the range - which I'm not sure if this is correct.
Assuming 2.5L/ha is OK I'm then converted that into quarts per acre. Based on this math 2.5L/ha is 1quart/acre.
Because my sprayer is only 25G I figured it might be easier to take the middle range of the water requirement, being 200L per hectare, and bring that down into gallons per acre. Based on this math 200L/ha is 21gallons per acre.
OK so I am at 1quart of chemicals per acre and 21gallons of water per acre.
My Fimco user manual says that in order to put down ~21gallons per acre I would need to have a spray height of 18", a pressure of 40PSI and I would need to be driving around 3MPH.
