Product Overview

Tupersan Herbicide is for pre-emergent control of listed weeds in newly seeded or established plantings of blue-grass, fescue, redtop, smooth brome, perennial ryegrass and many cultivars of bentgrass. Tupersan can be applied at the time of seeding without causing injury to germinating seedlings of most cool-season grasses. This high degree of selectivity allows you to seed later in the spring when soil temperatures are warmer and more conducive to seed germination. Because Tupersan is a wettable powder that is mixed with water, it allows you to spot treat areas that may be difficult to treat with granular pre-emergents.

    Pre-emergent crabgrass

    By Gary on 04/03/2011

    Verified Purchase

    This product allows new planting of seed right away, not 4-6 weeks later.  This size bag will last me several years.  It mixes well in my 2 gallon hand held sprayer, but the directions do not specifically address mixing by volume.  I think this would be most helpful for the homeowner for yard use.

    mixture rate****

    By Rob on 07/23/2012

    What don't people understand about "1 1/2 to 4 1/2oz per 1000 sq ft?" That is the mixture rate, so if you could get 12 lbs in a gallon of water and spray that gallon over an acre area that is your rate!!!! the best way to deduce this is to fill your sprayer say it's 5 gallons with water set your flow and tow it for for 1000 sq ft. judge how much water it took to reach the 1000 sq ft limit you measured off. if it took 2 1/2 gallons at the speed and flow you were pumping you'd mulitply 2.5*(1 1/2 to 4 1/2oz) and get 3.75 to 11.25oz for every 2.5 gallons of water, so your 5 gallon sprayer can apply 2*(3.75 to 11.25oz) for every 2000 sq ft and every 5 gallons of water. remember you're not diluting the product you just need to ensure you're putting it down at the rate recommended, they don't care about how much water you use to cover that area.

    Tupersan 50 WP

    By Donna on 04/25/2012

    Verified Purchase

    We don't know if this works or not as it just recently got warm enough to start yard work. We as of now have applied the product, seeded, added dirt, seeded again and are awaiting the results. The only complaint we have right now is that the directions for mixing the product were not very clear so we are just hoping we did it right. Would be nice if they would just come out and say - mix 8 ozs with 1 gallon of water - or something like that.

    Best pre-emergent for flexibility

    By Keith on 02/16/2018

    Prevents weed emergency very well, to dilute, and can lay down grass seed whenever the mood strikes me. Plus no mixed in cheap fertilizer. Makes lawn management much more flexible.

Questions & Answers

Have a question about this product?
  
Q
What is the usage rate and square footage coverage for small scale (1 acre) applications?
A

The first thing you need to know when using an herbicide such as Tupersan WP is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 1 1/2 oz - 9 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 1 1/2 oz - 9 oz of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

Q
How much Tupersan 50 WP do I need to add per gal for 1000 sq ft?

Can I use a hose end sprayer? If so, how much product per gal do I mix up to put in hose end sprayer?

Q
Does this product work to keep crabgrass from Bermuda grass?
A
This product will suppress crabgrass, but it is also labeled to suppress Bermuda grass.  This product is really intended more for golf courses that are trying to keep crabgrass and Bermuda grass from creeping onto the greens and fairways.  For keeping crabgrass out of Bermuda, we recommend Drive XLR8.  It is labeled for treating crabgrass on Bermuda turf.

Q
What to use to kill Bermuda grass in landscaped areas?

I want to keep Bermuda grass out of my garden, that is surrounded by my lawn. My thought is to use this around the edges of the garden. Is there a smaller package available for small applications?

A
If you are looking to keep Bermuda grass out of landscaped areas, then your best option would be to use Fusilade II which kills grassy weeds selectively, or to spray a barrier of glyphosate around the perimeter of the bed as well to keep grass out.  It is also recommended to use an edger to cut off grass encroaching into the beds.  Tupersan is more for broadleaf weeds out of turf grass, and you need something that kills turf grass.
