How to Make a Weed Dabber

The tool that I am going to tell you about is for using herbicides such as RoundUp. The biggest mistakes that people make when using nonselective herbicides like RoundUp is overspray getting the herbicide on plants that they did not intend to spray, and over applying the product. If you spray to the point of run off, you are applying way too much. The weed dabber is a tool used for spot treating weeds without getting the herbicide on other plants. Start by going to your hardware store and buying a piece of ” PVC pipe.

You only need a piece ” long, but they might make you buy a ‘ section. It’s pretty cheap though. You’ll need a plastic PVC cap for one end of the pipe, and on the other end you’ll need an adapter to convert the PVC pipe to a standard pipe thread. You’ll have to let the clerk at the hardware store help you find the best combination of fittings to use. What you need to do is to get the PVC pipe reduced down to a male garden hose type fitting.


Hardware stores sell brass fittings that convert standard pipe thread to the same thread used on garden hoses. Probably what you’ll end up with is an adapter that will convert the ” PVC to ” male pipe. Then an adapter to convert the ” male pipe to a male garden house fitting. They also make a cap that you can install on the end of a garden hose, you’ll need one of those. This cap must have a rubber garden hose washer in it so it seals properly.

The PVC fittings have to be glued on so you’ll have to pick up some PVC pipe glue and cleaner. You have to use the cleaner to remove the film and gloss from the PVC pipe and fittings before you glue them. Once you have them cleaned, just apply a coating of glue to both the pipe and the fitting, slide the fitting on and twist it at the same time. Hold the fitting tight for seconds and it will be glued tightly. Cut a piece of pipe long and glue the pipe cap on one end, and the PVC complete guide to pipe thread adapter on the other end.
