    Killing Florida nutsedge

    By Ralph on 08/27/2017

    Basagran kills yellow nutsedge without hurting Bahia grass, which greatly simplifies my yard care. Some agents to kill nutsedge are not to be used on Bahia.

    Killing yellow nutsedge in clover food plots.

    By Tim on 07/17/2017

    This product can be used in perennial white clover food plots to help control yellow nutsedge. Follow product directions for application and use crop oil. You will burn clover a bit but it will be fine. Once again, follow recommended application rates. Important thing is that it will help control yellow nutsedge in a perennial white clover plot. It also mixed successfully with clethodim for grasses. I have no complaints with the service, price or shipping.

How many ounces of Basagran T/O per gallon of water for spot spray in an established lawn?

This mixing rate of Basagran T/O depends on big of an area you are wanting to spot treat. Please refer to the Mixing Table on page 4 of the Basagran T/O label. The label also warns that applying this product as a spot treatment can result in excessive dosage and possible turf injury.

Area to Be Sprayed / Amount of Basagran T/O / Amount of Water

200 sq ft / 1 teaspoon Basagran T/O / 0.2-0.4 gallons of water

400 sq ft / 2 teaspoons Basagran T/O / 0.4-0.6 gallons of water

1,000 sq ft / 5 teaspoons Basagran T/O / 1-2 gallons of water

1 acre / 2 pints of Basagran T/O / 40-80 gallons of water

Sprayer Calibration Suggestions / Hand Sprayers:
1. Stake off a 400 square foot area of turf for practice. This
is an area 20’ (7 steps) x 20’.
2. Add a measured quantity (1.5 gallons for example) of water to the sprayer and uniformly spray the 400 square foot area. Measure water remaining to determine the
amount applied per 400 square  foot area. (Note: A minimum of 3 pints per 400 square feet is recommended).
3. Prepare the spray solution according to Table 1. Application Rates for Turf.
Example:Assume that in Step 2 the 400 square foot area was uniformly covered with 0.5 gallon of water. Referring to the table, add 2 teaspoons of Basagran T/O per 0.5 gallon of water for each 400 square foot of turf to be sprayed. (Note: Using this mix to spot spray individual weeds may result in an excessive dosage and possible turf injury.)

What oil and at what concentration to use with Basagran T/O Herbicide

What oil and at what concentration to use with Basagran T/O Herbicide?

When an herbicide calls for oil, it is referring to a surfactant.  Surfactant helps the herbicide stick to the waxy coating of the weeds and lawn you are applying it to.  It improves the effectiveness of herbicides greatly.

How much Basagran T/O Herbicide do I use per gallon of water?

I have 3 acres that is getting infested with yellow nutsedge and I have a 25 gal pull behind lawnmower sprayer. Not sure how much Basagran to buy.


Per the Basagran T/O Herbicide Product Label: For yellow nutsedge, apply no more than 0.75 fluid ounces per 1,000 square feet (2 pints per acre) at one time. Make a second application 10-14 days later. Apply no more than 1.5 fluid ounces per 1,000 square feet (4 pints per acre) in one season. 

On average you will use 40-80 gallons of water per acre depending on lawn thickness and weed size/growth stage.
