It seems like most people are buying premixed products similar to Trimec or 3way for broadleaf control. A person can buy 2-4d, dicamba and mecoprop seperately and mix them for about $15 a gallon in a ratio similar to most trimec products. I am not including carfentrazone, but I know that it can be bought individually also. I would like to hear from someone who has bought seperately and has bought premixed. I want to know their thoughts on which makes more money when everything is said and done. I realize that it would be almost impossible to mix like this for a backpack, I am talking about 50 to 100 gallon tanks and up.
