shouldn't be a problem...just don't spray 24d if its too warm....your actives turn to gas at 85 deg...I did a small plot in my yard that way and spot treat in the turnip and rape with 24d glypho mix and haven't gotten residual burn out

Yes, 2,4-D does have some residual and germination problems could result especially on sandy soils as both seeds will be planted very shallow. I sell quite a bit of 2,4-D ahead of soybean planting, another susceptible crop, and the general rule is wait a week for each pint/ac of 2,4-D applied before planting. Double the wait time if using the amine formulation. I would apply that same rule in this situation.

I appreciate the insite Tim! Looks like I might have to delay planting a couple weeks than. What would you recommend for an application rate on the 2,4-d?

 

I'd run a pint/ac of 2,4-d with your glyphosate and surfactant. Could double rate but will need to wait longer. A pint lets you plant the next week

I've had great results with this mixture on the lambsquaters that have been giving me fits.

 

With an app. rate of a pint per acre, how much water in the tank would you run. I plan to spray tomorrow with gly and 2-4d for some rye plantings later in August.

I have a 3-pt boom sprayer and wondering exactly how much water/gly/amine 2-4d? Running four nozzles 40 psi about 5 mph.

 

Every sprayer is different. Best way to find out is to measure a half or full acre and spray it with just plain water. Then you know how much water it'll take, then you add in the other stuff and whala!

 

Boom sprayer calibration.

 

BlackRhino, There's a couple ways to calculate how much water is needed. I've used the method L2H has posted and it is the most accurate.

The way I do it now has proven to be accurate for food plot situations and is easier. Every nozzle that I've seen has a number stamped on it. Something like A110005vs, XR8002vs, XR11002SS, etc. I compare the nozzle to the online spray chart from that manufacturer to get water volume per acre based on the speed I want to travel.

For example: Most Fimco sprayers will have XR8002 or XR11002 nozzles. The chart states that 40 psi and 5mph will result in 11.9 gallons of water per acre. Therefore a 25 g sprayer run at that pressure and speed will cover about 2 acres per fill. Increasing the speed to 6 mph will reduce the water volume to 10 gallons per acre. http://www.teejet.com/media/433011/010_cat51-us_lores.pdf

Here is the chart for the above parameters. It is the yellow section. Teejet nozzles are also color coated for easy id.

Of course you may have a different nozzle and will need to find the corresponding nozzle chart. Showing my age here. Before GPS, auto shut offs, spray controllers and such, almost all commercial applicaations were based on speed and pressure. Hope this helps.

Great information guys thank you!
