From my previous post thanks for the help with the sprayer. I am going to get a 40 gal from TSC. Not the best one I saw but it fit the budget and seems solid. Now for application. I would like to apply 2-4-D with Amine (hope I spelled that right) to kill dandys and other weeds. I have always used 2.5 gal of weed killer to 195 gals water (200 gal sprayer) and spread that over about 3.5 acres. Doing this twice does the whole yard. Question. Is that a correct mix for the size yard. I know there are other variables such as spray tip, application speed, etc.... But am I close enough to a correct mix with the 2.5 to 195 mix, or am I needing something else. My results so far are not bad but I know they could be better. From reading the posts here because of how this is drawn down to the root of the plant this is not a chemical where more is better and less is OK. Just looking for a good mix. Thanks in advance.
