Pylex Herbicide is a highly effective post-emergent herbicide that is specially formulated to control goosegrass and bermudagrass in cool-season turf. It has an active ingredient that is known for controlling grassy weeds and a broad spectrum of broadleaf weeds. It is a systemic herbicide that may be applied as a spot or broadcast spray to both non-residential and residential turfgrasses. Pylex Herbicide is ideal for use in areas such as parks, airports, schools, sod farms, golf courses, houses of worship, cemeteries, lawns around residential and commercial establishments, athletic fields, and roadsides. It is easily absorbed by the roots, shoots, and leaves of plants, making it highly powerful. A herbicide that targets unwanted weeds including crabgrass, goosegrass, nimblewill, bentgrass, chickweed, clover, bermudagrass, amaranth, and dallisgrass. For better and safer results, ensure that the product is used with a crop oil concentrate.

Directions For Use
It is a violation of federal law to use this product in a manner inconsistent with its labeling. This labeling must be in the possession of the user at time of herbicide application.
DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your state or tribe, consult the agency responsible for pesticide regulation.
Observe all precautions, restrictions, and limitations in this label and the labels of products used in combination with Pylex herbicide. The use of Pylex not consistent with this label can result in injury to crops, animals, or persons. keep containers closed to avoid spills and contamination.
Unless otherwise directed in supplemental labeling, all applicable directions, restrictions, precautions, and Conditions of Sale and Warranty are to be followed.
Apply Pylex to actively growing weeds as a postemergence broadcast or spot spray in labeled turfgrass species at the specified rate and growth stage. DO NOT exceed the labeled application rate or fail to comply with use specifications in Restrictions and Limitations.
For best results, weeds should be actively growing and not under stress from lack of water, excessive water, low fertil - ity, mowing shock, excessive hot or cold temperatures, or injury from other herbicide applications.
To achieve consistent weed control, a crop oil concentrate (COC) or methylated seed oil (MSO) adjuvant is required.
Apply Pylex during favorable growing conditions for optimum turfgrass tolerance and weed control. Turfgrass under environmental stress is more likely to show injury, such as transient bleaching, from herbicide applications. These symptoms are temporary, and turfgrass vigor is not affected.
Postemergence spot applications of Pylex herbicide may be made to susceptible weeds in tolerant turfgrass species. Apply 0.023 to 0.034 fl oz (0.7 to 1.0 mL) of Pylex per 1000 square feet of treated area. Spray coverage should be uniform and complete.
To maximize weed control and minimize potential turfgrass injury, DO NOT mow 2 days before through 2 days after applying Pylex.
Irrigation and Rainfall
If soil moisture is not sufficient before Pylex application, irrigation may improve weed control. For best results, DO NOT water or irrigate for 24 hours after application.
Tank Mixing Information
Read and follow the applicable restrictions and limitations and directions for use on all products involved in tank mixing. Always follow the most restrictive label use directions.
Physical incompatibility, reduced weed control, or turfgrass injury may result from mixing Pylex with other pesticides (fungicides, herbicides, insecticides, or miticides), additives, or fertilizers. Before tank mixing, a jar test is required to ensure compatibility of herbicides or other pesticides and/or additives. Refer to manufacturer’s labels for specific use directions, precautions, restrictions, and limitations before tank mixing with Pylex. Follow those that are most restrictive.

I know this stuff is expensive, but it works great. I had an infestation of bermuda grass on my lawn from a neighboring pasture. Two applications and reseeding of fescue and it's a new lawn. Follow the instructions. I followed the advice of the Virginia Tech ag extension. In in NC. Bermuda turns white after a couple of weeks. Second application killed off the remaining. For me, it beat the alternative of killing off the lawn with roundup and starting over.
if you can get over the price- this kills the bermudagrass

Okay the investment in terms of the package you need to buy is preposterous. You apply 0.7ML per gallon and have to buy 8 oz or 237ml.. which means you need to buy enough to make 338 gallons which treats 338,000 sq feet. For $500. But if you need to get rid of bermudagrass in fescue like my silly HOA demands, and can get past this investment challenge, the outcome is great.
I have to admit for the first 4 days I was convinced I made a huge mistake. Then it started visibly working. Now after 2 weeks the bermudagrass is turning white and the grass is green and fine. Wow
I have wasted way too much time in the past with ineffective solutions like fusilade & tenacity, finding just the right day, applying over and over etc. Triclopyr worked a little but is a bermudagrass discourager, not killer. I tried roundup one year but the bermudagrass just came back anyways. The roundup wasn’t that expensive but the grass seed was.
My pylex package came with a ml syringe (no needle) that is great for dispensing the very small amount (thanks). You need to buy the MSO. What I didn’t catch is that the pylex secondary label tells you to use triclopyr in addition to the mso- i took that as a very strong recommendation. So plan ahead with your domyown order. I would also recommend a dye if you are spraying enough.
The label recommends 2 or 3 applications finishing 3 weeks before seeding time, which means I can apply in the summer. Perfect. Cause that’s when bermudagrass takes over. I can’t tell you how next year will be but at least this is real progress.
Crazy expensive- yup. Only thing that works-check. Possible solution or at least significant gain for the first time in years in my struggle against bermudagrass in fescue- bingo. Highly recommended. All we need to do is get it in containers 1/8 the size
I’ve spent $$$ fighting Bermuda in my tall fescue over the past 12 years but achieved nothing more than moderate control. Ordered Pylex and applied it in September last year. I’ve had some trouble spots return as of late July it’s no where near as bad as previous years. I’m going to make an application in early August and a second in early September this year in hopes of knocking it out once and for all.
We were a bit nervous about making such an expensive purchase for a tiny bottle. We sprayed all our areas where Bermuda had just spread out of control. After the first week I starting to feel sick that nothing had happened, but by day 10 I was completely blown away. This stuff is amazing! The Bermuda is starting to take effect and our good fescue is left behind undamaged. I cannot believe this product is so effective. We are still waiting to see how it looks in the next week because we have heard and read that applying a 2nd time might be needed, but so far so good.
We also used this product with blue dye and made it so much easier!
Is there a similar product to Pylex Herbicide that kills bermuda grass (but does not harm fescue) but in a smaller size or more affordable price?
Yes, Fusilade II Herbicide would be a great and lower cost alternative to the Pylex herbicide. It can be used in a fescue lawn to kill bermuda grass. It can be VERY difficult to kill completely, and will take multiple treatment to get it done but Fusilade II is usually the go to product for this issue.
Apply 0.07-0.14 oz/1000 sq. ft (3-6 oz/A) along with 0.25% V/V (1/2 pt./25 gals.) of non ionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 day. Do not apply to desirable turf under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.
If you are suppressing bermudagrass and tank mixing Pylex with Triclopyr, should you still add a MSO?
I don't want to harm my TTTF with adding too much to the mix. Just want to know if the MSO is still supposed to be added along with the Triclopyr...
Pylex Herbicide states on the product label that MSO is the only type of surfactant that would be safe to mix with it. For bermudagrass it does state you need to do so and tank mix with a triclopyr product so would be safe when used as directed. Be sure to not apply to fescue during the heat of the day or when it is stressed by drought.
How can I measure out such a small amount accurately of Pylex Herbicide at 2 to 3 hundredths of an ounce per 1,000 square feet?
Does this product come with any such measuring device for typical 1-4 gallon pump sprayers?
Pylex Herbicide does come in a tip and pour measuring bottle. If smaller amounts need to be measured, most folks will get a child’s medicine dropper or other pipette from a local pharmacy to measure. These are almost always free.
How many ounces or mL of Pylex Herbicide and surfactant do I use per gallon of water?
Pylex Herbicide is mixed at 0.023 - 0.034 oz. per 0.75 gallon of water per 1,000 sq. ft. The amount of the surfactant will vary depending on the one that you have and dilutions can be found on the product label.
