How do you refill roundup pump and go

The Pump N Go can be refilled with either the Roundup Super Concentrate or Roundup Ready To Use Plus Refill Bottle.

To refill the Pump N Go with the Roundup Super Concentrate (purple cap), add 6.5 fl oz of the Super Concentrate to container and slowly fill with water.

To refill with the Ready To Use Plus Refill bottle, just slowly fill the Pump N Go with the refill container.

We do not recommend using Roundup Concentrate Plus (red cap) to refill the Pump N Go because it has different active ingredients and different information regarding use around edibles.

To open to Pump N Go container, please follow the directions below:

Stabilize container by holding between your feet

While holding the pump handle push down slightly and turn left (the pump will be out of the locked position)

The first time it is opened it will be difficult to open because for shipping safety the top is but on very tightly at the factory.

If you have any further questions, please contact us at 877-465-5160.

I borrowed a Roundup (max fill 2 gallon) sprayer. It was working fine, but I needed to refill the tank. Now I can't get it to spray. There seems to be plenty of pressure.

Look for particulate matter that plugs the spray nozzle. Remove the tip and test for flow. Sometimes older spray has particulate matter that comes out of solution.

I just want to know how much of roundup to put in the tank, you use air to disperse the weed killer?

Yes I do use it, you can put about 1qt of round up for every gallon of water. This should kill your weeds, for most precise mixing instructions check the bottle label.

How much roundup do i put in 3 liters of water

Round up is currently offered in a few variations. If you have the "Spray and GO" or the "Spray and Go" refill product do not add water. The ratio is already correct. Likewise for the "Redy-to-Use Plus", do not add water.
If you have the "Weed and Grass Killer Concentrate Plus", the ratio is 3oz/gallon water. 3 liters of water=0.79 gallons so use 2.4 oz of this type of Round Up.
If you have the "Weed and Grass Killer Super Concentrate", the ratio is 1.5oz/gallon water so you would use 1.2 oz of product mixed into 3 liters of water.
If you have a different product and just need to work out the conversion from gallons to liters, 1 gallon=3.78 liters.
Hope this helps.

How do i mix roundup concentrate plus

Roundup Concentrate Plus is the least concentrated mixable product Monsanto offers. Annual and perennial weeds can be controlled with a mixture of 6 fluid ounces of Roundup (12 tablespoons) per gallon of water. Small weed seedlings can be killed with half this strength: 3 ounces per gallon. When using Roundup Super Concentrate, mix 2.5 ounces (5 tbsp.) with a gallon of water to control most weeds and a half-strength solution for small weeds. Roundup Pro Concentrate is the strongest solution available. Spray a mixture of 2 ounces (4 tbsp.) on weeds and half that amount of concentrate on emerging plants. Since Roundup doesn't discriminate between weeds and other plants, use the least amount of herbicide possible to protect desirable vegetation.

NO. As a matter of fact, NEVER mix any yard chemicals. The results could be deadly. Even simple household cleaners when mixed can be deadly. I had a neighbor who mixed ammonia and chlorine bleach, (creating ammonium chloride gas), and needed hospitalization.
