How do I use Atrazine?

You can use Atrazine in many ways. One way to use it is through the hose-end attachment, which attaches directly to your hose without having to mix it and sprays up to 3,720 sq. ft. of lawn. If you choose to go with the concentrate, you need to mix a solution to spray on your lawn. 4.3 fl. oz. of Atrazine per gallon of water covers 500 sq. ft. of lawn. We recommend using our Chapin Lawn Sprayer for a hose-end attachment. Spray the product in broad strokes, making sure to give the target area even coverage. It is recommended that you spray your entire law, as it will also discourage the spread of other weeds into your lawn. Be sure to have at least a 2 hour rain fast after application to ensure proper absorption. 

If you plan to use Fertilome Weed & Feed granules, you’ll need a spreader to get broad, even coverage. Be sure to follow the recommended spreader settings on the back of the bags for your spreaders. After spreading, run your sprinklers for 15-20 minutes to water the product in. 

When should I use Atrazine? How often should I use it?

You should use Atrazine when the average high temperatures for the week of application is below 85F. Applying the chemical when the average high temperature is above that will burn your grass. The best times to use Atrazine are early spring, late fall, and all of winter. Take advantage of the cooler temperatures to get rid of weeds!

You should wait at least 6-9 weeks between applications to use Atrazine again. Using it too often and too soon may stress the surrounding area too much, so be sure to not overspray.

How do I use Weed-Out?

For the regular concentrate Weed-Out, mix 2 oz. in 1 gallon of water. Two ounces will cover 700 sq. ft., and a whole pint will cover 6,000 sq. ft. For the concentrate with nutsedge control, mix 5.5 oz. in 1 gallon of water. 5.5 oz. will cover 1,000 sq. ft. This dilution rate applies to warm season Florida grasses such as Bahia and Bermuda. Mix these concentrates in a hose-end attachment sprayer, such as our Chapin Lawn Sprayer, and spray in broad strokes to give your lawn an even coverage of the product. Be sure to have at least a 2 hour rain fast after application to ensure proper absorption.

For the ready-to-spray bottle of Weed-Out Plus Nutsedge Control, attach it to the end of the hose. It is already pre-diluted, so no mixing is not required. The bottle covers up to 5,800 sq. ft. Spray the bottle in broad strokes to give your lawn an even coverage of the product. Be sure to have at least a 2 hour rain fast after application to ensure proper absorption.

If you have a small property or only wish to spot treat certain areas, the ready-to-use bottle of Weed-Out Plus Nutsedge Control is perfect for you. It is pre-diluted, so mixing is not required. Thoroughly spray the affected area(s) with the product. Be sure to have at least a 2 hour rain fast after application to ensure proper absorption.

What is Dollar Weed Control?

Dollar Weed Control is a granular, post-emergent herbicide that not only targets dollar weed in your lawn but also many other types of broadleaf weeds. It contains Penoxsulam, a chemical particularly effective against dollar weed. You can use it on all types of grass except bahia.

How do I use Dollar Weed Control?

Before you spread this product, be sure to water your grass for 10-15 minutes with your sprinklers or hose. This will keep your grass hydrated after application while also increasing the attach rate of the granules to harmful weeds. Use a push spreader for Dollar Weed Control if you plan to spread it over your lawn. If you have a smaller lawn, a handheld spreader like our ScatterBox would come in handy. Use the appropriate setting listed on the back of the bag to make sure that your lawn gets the proper coverage. One bag covers 5,000 sq. ft. Make sure to have at least a 24 hour rain fast after application to prevent runoff. Do not mow for 24 hours as well. 

If you are applying this product during hot and dry periods of weather, which is typically May through early June in Florida, reduce the application rates by 50% to avoid dehydrating and browning the grass. 

When should I use Dollar Weed Control? How often should I use it?

You can use Dollar Weed Control any time of year. Dollar Weed Control is even safe to use in the summer, unlike other post-emergent herbicides like Atrazine or Weed-Out. 

You should wait 4-6 weeks to apply Dollar Weed Control again. Multiple applications may be necessary to completely treat the affected area. Do not exceed 2 applications in a 3 month period. 

How do I use Killzall?

Mix 6 oz. per 4 gallons of water. If you are using our hose-end attachment Chapin Lawn Sprayer, this is made easy by pouring the 6 oz. of Killzall in the bottle first, then filling the bottle up to the 4 gallon mark with water. One solution of 6 oz. covers 1,200 sq. ft. Spray the whole lawn in broad strokes to get an even coverage.

When should I apply Killzall? How often should I apply it?

You can apply Killzall to ProVista sod any time of year. Make sure you apply Killzall to ProVista St. Augustine when the grass is healthy. Stress may occur after application if the grass is already experiencing issues. 

Since Killzall is a powerful chemical, one application is enough to kill most weeds in your lawn. Repeat applications are often unnecessary. Do not exceed more than 3 applications in a year. Use pre-emergent herbicides between applications to discourage the need to use Killzall more frequently.
