Wide range of broad-leaved and grass weeds

Katana® is a long-lasting, non-selective, residual herbicide for pre-emergent application, which remains active on surfaces it is applied to for up to 5 months. Katana® can be applied to a number of non-crop surfaces as well as around amenity vegetation preventing the emergence of susceptible broad-leaved and grass weed species.

It controls a broad spectrum of annual and perennial broad-leaved weeds and grasses on natural surfaces not intended to bear vegetation, permeable surfaces overlying soil, hard surfaces (railway ballast only), and around amenity vegetation. It can be applied once per year at a rate of 150g/ha.

Katana® has a limited effect on very young weeds and should be tank mixed with glyphosate for effective post-emergence control alongside the long-lasting residual activity of Katana®.

For best results the surface should be left undisturbed after application to ensure that the barrier effect created by Katana® remains active.

This 50g bottle is sufficient to treat 3,333m2 for up to 5 months.


Target Species

Katana® gives pre-emergence control by forming a surface barrier that prevents germination of a wide range of broad-leaved and grass weeds.


Instructions for use

Where to use

  • Natural surfaces not intended to bear vegetation - Areas of soil or natural outcroppings of rock that are not intended to bear vegetation
  • Permeable surfaces overlying soil - Any man-made permeable surface (excluding railway ballast) that overlies soil and is not intended to bear vegetation
  • Hard surfaces (railway ballast only) - Any railway ballast impermeable surface that is not intended to bear vegetation
  • Amenity vegetation (around) - Any areas of semi natural or ornamental vegetation, including trees (see product label for susceptible non-target plants)

When to use

Katana® is most effective when it is applied in the early to late spring before weeds the have germinated. If weeds are visible Katana® should be tank mixed with a suitable foliar herbicide such as glyphosate.


How to use

Maximum Treatments Pack Coverage Application Method Application Rates Water Volume Spray Quality
1 per annum 3,333m2 Conventional knapsack sprayer 150g/ha 200-600l/ha Medium
Vehicle mounted sprayer


  • Add half the required water to the spray tank
  • Add the required amount of Katana® to the spray tank and agitate thoroughly
  • Top-up the spray tank with water to the required level
  • Use immediately
  • For maximum persistence do not cultivate or rake the area following application
  • Clean application equipment with a diluted ammonia solution following use

Additional Information

  • A Local Environment Risk Assessment for Pesticides (LERAP) must be carried out in accordance with CRD’s published guidance before each spraying operation from a horizontal boom sprayer
  • Can only be used on natural or porous surfaces such as gravel where the user can establish that the underlying surface is soil, and railway ballast surfaces
  • Must not be applied to any non-porous man made surfaces
  • Avoid spray drift onto non-target plants
  • To avoid build up of resistance do not apply this or any other ALS inhibitor herbicide for control of grass weeds more than once per year
  • When treating around amenity vegetation do no apply near species that have been planted for less than 2 years
  • Do not allow direct spray to fall with 5m (horizontal boom and train sprayers) or 1 m (hand held sprayers) of the top of the bank of any static or flowing water body

Active Substances

Flazasulfuron

Bio-Chemical Mode of Action: Flazasulfuron belongs to the inhibition of Acetolactate Synthase (ALS) group of herbicides.

Acetolactate synthase is an important enzyme involved in the biosynthesis of branched-chain amino acids. ALS inhibitors interrupt this process causing the plant to initially become chlorotic before necrosis of plant tissues followed by whole plant death occurs.

Mobility: Flazasulfuron is a systemic penetrant which means that the active substance can be translocated downwards through the plant within the phloem (sugar conducting tissues) and upwards through the plant within the xylem (water conducting tissues).

Application timing: Residual ALS inhibitors are best applied prior to the emergence of weed species.

Resistance: ALS inhibitor herbicides pose a high-risk of resistance particularly for grass weed species including black-grass, Italian rye-grass and wild oats. To reduce the risk of resistance follow label instructions and rotate use with herbicides with differing modes of action.

Didn't use for laptop but....
Style: Deluxe
Fantastic for my desk. I ended up using this to mount a Topping DAC under my desk and I used the side cubby to put my Google Nest Mini and Broadlink RF device. Got all that off my desk and everything tucked away just perfect. I haven't used the headphone mount yet, but I plan to use that to, low and behold, hang headphones! These are easy as heck to install and strong enough to hold up anything that will fit in the space for the most part.

Solid, Space-Saving Solution for My Desk
Style: Deluxe, Style: Deluxe
The Under Desk Laptop Mount Bundle was easy to install, but I recommend taking your time to ensure any connections to the sides of your computer can be made through the openings of the bracket. It’s important to double-check this step to avoid any issues with being able to plug in any computer devices, such as power, monitors, headphones, etc. In my photos above, I did not use the included hook or basket due to where I was locating my laptop under my desk. I was unable to attach the basket due to my connections to my computer. Note that the basket can only be added to the left side of the system. It would be great if the design were improved to allow the basket to be added to either side of the system. That being said, I do like you can choose to install the basket and/or hook, or leave them off. Even with this minor design flaw, this bracket is a fantastic space saver! This is perfect for my stand-up desk, and is a nice upgrade to my workstation.

Likely the best underdesk laptop mount
Style: Deluxe
This product is actually pretty amazing. As a laptop mount, it is incredibly well designed. They have included foam padding strips for all the sides to protect your laptop from scratches when using it. They have also included a couple sheets of cardboard spacers, to use when aligning the mounting brackets. This makes sure you don't install them too tightly for your laptop, and it's a really nice touch. The side drawer is fully metal, which makes it really easy to magnet mount flashlights underneath for quick access. And the best part of all, they include 25 cable clips, 20 small ones, and 5 big clips. This adds incredible value to this package. One thing to keep in mind though, this product uses 3/4" long screws to securely mount under the desk. If your desk does not have a 1" thick tabletop, you may need to get some washers to mount the brackets, or else they will puncture through the desk board when fully screwed in. Be careful if using a powerdrill to install this product, because it'll drill so fast it'll punch through your tabletop before you can stop it. Although the product comes with 3M VHB for mounting, I wouldn't rely on that if you plan to put a laptop here. Your laptop's value is too high to take a risk using an underdesk mount that isn't properly held in place with screws. Despite that, I still highly recommending this product if you're looking for an underdesk laptop mount. The extras it comes with more than justifies the price for the product itself. Just be sure your tabletop board is thick enough to install it.
