I want to do some spot spraying with one of the hand sprayers you pump up by hand. I bought some 2-4 D, and Generic Roundup, and both give mixing rates according to ground speed etc, etc, but what about mixing for just a hand sprayer? What ratio do I use for a gallon of water? Thanks.

spot spraying small weedswith roundup, use a 2% solution. if your generic doesn't have surfactant, add some dish soap.

41% glyphosate (generic roundup) - 2.5 oz per gallon.

2-4D, what ever the lable says, there are many different consentrations available. The last gallon I bought was 65% and I remember mixing at 1qt per acre in the boom sprayer.

Remember 24D has alot more residual than round up when its mixed strongly.


Good luck

Just wondering? what's the dish soap for? wetting agent?

alot of vegetation has a waxy substance on the surface. water + herbicide can sort of bead up on the plant. the soap prevents the beading up. add just a squirt or two, once you've added herb and all the water to your tank.

thanks for the help.

Why do you want to mix roundup and 24D, Roundup will kill everything , you would be wasting the 24D. if you just want to kill weeds and save the grass then use the 24D. I mix 3 oz of R/U to a gal of water

I'm not mixing, just wanted to know what rate to mix for each. will be spot spraying some of my pastures with 2- 4 d and my RR Soybeansin my food plot.

We always go by Ed Spinazolla(QDMA FOOD PLOT BOOK)and he says 1/2 cup per gal. Might be around4 oz or so. We did this last week and it burned up good. Also added some sprayable amonium sulfate also.
