Roundup
Experienced gardeners share their insights in answering this question :
If you haven’t tried it, rotate the collar that closes/adjusts the spray, and/or undue the locking clip if yours is so equipped. The only other source is a disconnected
emulsion tube (inside the cannister) or a severely clogged orifice in either the out line or the spray nozzle. It won’t take but 3 minutes to check the lot, and unless there is no hole in the nozzle to begin with, you’ll be killing weeds in no time. One last thing though: Is the pump (actual an aspirator) building up enough vaccuum? If not the inner line may be broken, or the pivot/pick up attachment at the cap juncture is not securely working. That’s it!

How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Re-prime the sprayer by engaging the trigger for up to 30 seconds, until it begins to spray. Check the nozzle for clogs. If the sprayer tip is clogged, don`t use soap or other cleaning agents to clean it. If necessary, clean the outer sprayer surface only with a damp towel.
Make sure the pump/lid is screwed on very tight. If it`s not tight enough it will not hold pressure. Be sure to pump handle vertically up and down, off centre pumping motions will not build pressure efficiently. Pressure will decrease with storage.
Chances are there is dirt or debris somewhere in the discharge line. Most likely the nozzle is plugged. RELEASE THE PRESSURE by SLOWLY opening and removing the pump. Then, unscrew the nozzle cap and check to see that it`s clear (see diagram below).
You can pump up the tank okay, but it won’t hold the pressure. Solution: Check the pump gasket at the top of the pump cylinder (tank); it may be cracked or damaged and not forming a seal with the tank cap. Replace the pump cylinder gasket and make sure that it fits tightly around the top of the pump cylinder.
Check the Tube
Instead, it`s likely your spray bottle isn`t spraying properly because the tube has disconnected from the nozzle. To check this, poepping says to push down on the sprayer. If you can press down with ease, but the product isn`t coming out, it`s likely a disconnect with the tube.
It`s possible that bits of the product have hardened onto the nozzle where the spray comes out, says Paul Halter, a sunscreen innovator with Goddess Garden. The best way to fix this is by running the nozzle under warm water until the caked on product is removed.
With the above in mind, you should consider nozzle configurations that deliver 10 – 15 gal/acre that produce medium to coarse droplet sizes at pressures between 25 – 40 psi.
Yes, you can use a pump sprayer to spray Roundup (Glyphosate). I have used a pump sprayer for years to apply Roundup around my own residence. Some sprayers will last longer than others before issues like leaking and plugging may occur.
Glyphosate, Weeds, and Crops
multiply and create a resistant population. Herbicides do not cause the mutations that result in resistance. Rather, an extremely rare genetic trait that allows a weed to survive glyphosate may exist in the natural population.
On top of that, research suggests that even at very low concentrations, glyphosate mimics human hormones, potentially triggering or speeding up the growth of tumors. Nearly half a century after its introduction to agriculture the chemical is ubiquitous in the environment.
Reducing the water volume to the minimum required for good coverage will help to ensure maximum effectiveness of glyphosate products. Hard water can also reduce the activity of 2,4-D amine.

I got a roundup sprayer at a garage sale. I don’t know how to fill it. It has a model # 020p10 Any assistance you can provide will be greatly appreciated as there is no manual. Larry
ANSWER : The handle pushes down and locks to be carry or to unscrew it. Push handle down, then twist left to unscrew. It may take a bunch of force to start. Better to hold the sprayer down and relieve all pressure before doing the unscrew.
