Kathy bought some Grazon Next weed spray from Tractor Supply last year and I was not able to spray so I am spraying now. I noticed that it does not contain 2-4-D so I went online and the Grazon Next H L which contains some 2-4-D. I don't have very good luck with Tractor Supply unless I'am buying Nuts and Bolts and I don't think much of their Cattle Feeds either.
What I would like to know is, what brand of Weed Killer with 2-4-D and surficant is the best for Cattle Pastures. Need to kill the weeds and not the grass.
Any constructive advice will be appreciated.
I don't know of any herbicide that contains adequate or proper ratios of 2,4d and surfactant. Best to custom mix your own--just add the needed amount of 2,4d to whatever primary herbicide you are using then add the surfactant to match your total volume.
There are some multi ingredient herbicides available, such as Crossbow, which is pretty much 2,4d and Remedy premixed, but will have a lower % of one or another per gallon--you need to read the ingredients and ratios of active ingredients:inert ingredients. It's sometimes easier and less expensive and more effective to custom mix your own to match your weed/invasive problems. Again, just using remedy and 2,4d as an example:
1 gal of Remedy Ultra contains:
Triclopyr-60.45%
Other (inert) ingredients- 39.55%

1 gal of Crossbow contains:
Triclopyr-16.5%
2,4d-34.4%
other (inert) ingredients 49.1%
They had to decrease something to add the 2,4d, so they decreased the amt of active ingredient triclopyr.
Grazon Next and GrazonNext HL both have a form of 2,4d ( 2,4-dichlorophenoxy)in them--just different ratios.
GrazonNext:
