What type of sprayer would you use?

[ponytug]

How far a gallon goes depends on lots of things; how wide a strip you are spraying and how heavily you apply it. The recommend rate is on the container, but as an example for glyphosate (Roundup(tm)) from the Pioneer websites

• The standard rate of glyphosate is 0.75 lb acid equivalent per acre. The rate should be increased to 1.13 for weed height ranging from 6 to 12 inches and to 1.50 for weeds > 12 inches tall.

Sorry if it was the wrong weed. This one, perhaps, also known as licorice weed?

If it is licorice weed, you might have something you can sell...

All the best,

If you buy a 3pt unit you can also put it in the back of your utv if you dont want it on the tractor . I have a 25 gal 12 volt sprayer and i spray lots of fields and around my lake it works great , I also built a 55 gal sprayer out of a black poly drum. it also works well especially if it is a long way back to get a refill.

I just read about calibrating sprayers. That's something you should do to make sure you spread the correct rate.
From this site... Calibrate Your Sprayer Now - Here is an Easy Way to do it | Agronomic Crops Network

1. Fill the sprayer tank (at least half full) with water.
   
2. Run the sprayer, inspect it for leaks, and make sure all vital parts function properly.
   
3. Measure the distance in inches between the nozzles.
   
4. Measure an appropriate travel distance in the field based on this nozzle spacing. The appropriate distances for different nozzle spacing is as follows: 408 ft for a 10-inch spacing, 272 ft for a 15-inch spacing, 204 ft for 20-inch spacing, 136 feet for a 30-inch spacing, and 102 feet for a 40-inch spacing.
   
5. Drive through the measured distance in the field at your normal spraying speed, and record the travel time in seconds. Repeat this procedure and average the two measurements.
   
6. With the sprayer parked, run the sprayer at the same pressure level and catch the output from each nozzle in a measuring jar for the travel time required in step 5 above.
   
7. Calculate the average nozzle output by adding the individual outputs and then dividing by the number of nozzles tested. The final average nozzle output in ounces you get is equal to the application rate in gallons per acre. For example, if you catch 15 ounces from a set of nozzles, the actual application rate of the sprayer is equal to 15 gallons per acre.
   
8. Compare the actual application rate with the recommended or intended rate. If the actual rate is more than 5 percent higher or lower than the recommended or intended rate, you must make adjustments in either the spray pressure or the travel speed or in both. For example, to increase the flow rate you will need to either slow down, or increase the spray pressure. The opposite is true when you need to reduce application rate. As you make these changes stay within proper and safe operating condition of the sprayer. Remember increased pressure will result in increasing the number of small, drift-prone droplets.
   
9. Repeat steps 5-8 above until the recommended application error of +5% or less is achieved.

I sure appreciate you guys taking time to help me out here. This is great information! Thank you!

Have any of you used a pump for the sprayer but with different holding tanks? I'm thinking it might make sense to have 2 or even 3 tanks but one pump. One for weed killer, one for fertilize and one for water. I don't see this as an option on any of the sites I'm looking at. Wouldn't this make sense?

Most pumps and plumbing are firmly attached, which makes switching impractical.

You can, and should, clean your tank and lines. Just be careful if you are switching between herbicide and anything else.

All the best,

I found a site that sells everything related to sprayers. I'm going to see if I can build something practical to where I can keep weed killers in one tank and fertilizer/water in another. I'll keep you posted and let you know how it works out. Thanks again for the help!

For spot spraying weed/brush killer I normally mix 4 oz concentrate per gallon of water. That's a pretty stout mix, and Crossbow will do a job on blackberries, poison oak, etc. That works out to 1.5 gallons of Crossbow in a 50 gallon sprayer. That will do about a mile of brush line 20' wide.

Usage is a bit of self discipline, I get twice the coverage that SWMBO does but she wants to soak everything which simply is not needed with roundup, blackberries were our biggest problem at the last place, as we are a warmer climate they do not die back in winter, we don't have them here but capeweed is a PITA and will need to be sprayed in spring.
