Should I add soap to 2,4D for spraying

[Von]

I am going to spray my five acres of yard this evening with Amine 400 2,4D for broad leaf weed control. I do this once a year, and get an alright "kill". But I read some where on the internet to add dishwashing soap to the mix to lower the surface tension of the plants leafs. Does anyone know how much to add and if it works at all? I use a large tank sprayer, that will hold 300gals. I use about 185 gal. of water to 2 1/2 gal. of weed killer to do all five acres. If anyone has and suggestions or better ways to get a good kill let me know ASAP as I hope to be spraying around 7 tonight. Thanks!

Von,
I would say a couple of good squirts. I don’t know that I have saw anything printed that told an exact amount. After you mix it, spray it on something slick. If it still beads, then you need to put in some more.
