Pylex Herbicide

Pylex Herbicide offers a new use pattern for the active constituent, Topramezone, for the control of warm season grass and broadleaf weeds in cool season turf. This new and unique use pattern enables the safe and efficient removal of broadleaf weed species and warm season turf species, including Buffalo grass, Kikuyu, Couch and Queensland blue couch, in cool season turf on Bentgrass greens.

As the only solution for selective weed control on greens, Pylex Herbicide is pioneering an unmatched combination of turf safety and exceptional efficacy. Featuring pre-measured packaging and highly selective control, Pylex increases labour efficiencies and turf safety, minimising chemical calculation risks.

Incorporating Pylex Herbicide into Bent grass greens management

Considering the highly specific and targeted behaviour of Pylex Herbicide, it is important to ensure correct application for reliable results, taking particular care with sprayer calibration and conditions conducive for success. Read our Calibration Tips for Pylex to ensure you get the most out of your Pylex applications.

In addition to calibration of equipment, there are a number of factors which affect control and should be considered when planning your Pylex Herbicide program. Factors that affect control:

• MSOs are essential to assist Pylex Herbicide in penetrating the leaf for consistent control. Required rates for MSO adjuvants can be found on the directions for use table of the Pylex Herbicide label.
• Early encroachment and actively growing weeds are more susceptible than more advanced growth stages. Pylex Herbicide should be applied when weeds are not in their strongest, fittest growth stage and state for best results.
• Good coverage of the target weed is essential to achieving reliable control. Even coverage enables Pylex Herbicide’s excellent translocation capacity to be maximised. This factor takes into account calibration of spray equipment, and use of a high quality MSO.
• Pylex Herbicide is a light-activated technology, as it works to disrupt the photosynthetic cycle of target weeds. Conditions conducive to maximum photosynthesis (moist,warm, bright sunshine) are ideal.
• Cool weather can reduce the speed of activity. Pylex Herbicide’s performance is maximised in consistently bright, warm conditions.

What is the ideal use rate for Pylex Herbicide?

• For Bent grass greens: 0.375 ml/100m2 in 4-6L of water + 0.5% MSO is the labeled rate of application. At this rate two repeat applications 21-28 days apart will be required.
• For other cool season turf: 0.75 ml/100m2 in 4-6L of water + 0.5% MSO is the labeled rate of application. At this rate a single application will likely be sufficient.

What is the typical reapplication timing for Pylex Herbicide?

Typical re-application for Pylex Herbicide is every 21-28 days.

Are 3 applications of Pylex Herbicide likely to be required?

Proposed application strategies outline the requirement for two repeat applications in most cases (on Bent grass greens). The requirement for three sequential applications may be required dependent on the time of year and establishment of the target weed.

Is there a risk of turf injury after scarifying?

Local trials have demonstrated that scarifying did not result in increased risk or performance when Pylex Herbicide is applied. However, it is important to ensure turf is not stressed prior to application.

What is the residual timeframe for re-seeding around a Pylex Herbicide program?

• Do not apply for 28-days after seeding tolerant turf.
• Avoid application 7-14 days before seeding tolerant turf.

What is the likelihood of translocation into the collar?

Clear defined lines with a flat fan nozzle, can be achieved when treating close to the collar. Users should take care in ensuring the edge of the spray does not cover the warm season collar, which will be affected by the chemistry if treated. Tracking on shoes doesn’t occur once spray has dried.

Can Pylex be used in conjunction with PGR programs?

Yes, Pylex is suitable for use in a spray program which includes Trinexapac-ethyl.

When are the visual effects likely to be observed after applying Pylex Herbicide?

Visual effects on susceptible species occur 7-10 days after application.

Are there any concerns for turf injury when applying Pylex Herbicide to Bent grass greens of mixed swards?

Pylex Herbicide is suitable for use on mixed swards. In some cases, some minor transient discolouration of some Bent grass cultivars may be observed in the first 7-14 days following application. In all cases during local trials, the Bent grass quickly recovered from this discolouration and it has not been observed in all treatments.

Considering the highly specific and targeted behaviour of Pylex Herbicide, it is important to ensure correct application for reliable results, taking particular care with sprayer calibration and conditions conducive for success.

4. Combination of spot applications and inner green treatment

Application Guide

Ideal application windows for Pylex Herbicide should take into account local factors, and factors affecting control

Read our Pylex Application Guide to discover the most effective Pylex program tailored to the target weeds present in your course.

Autumn brings the slowed growth of our target warm season grasses, cooler ambient and soil temperatures. The vast and diverse nature of the Australian turf market sees these typical Autumn conditions vary across climates. Turf managers should be observing changes in weather, plant growth, and soil temperature on their sites, allowing them to gauge when their Autumn and Pylex season has arrived.

Spring offers a second opportunity for application as light intensity is maximised while also favouring susceptible weed growth stages. The below proposed programs capture a re-application interval of 21-28 days with applications dependent on weed establishment. There are opportunities for additional applications, and movement outside of this seasonal window, dependent on climate and establishment of the target runners.
