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.

The only chew toy that has actualy held up...for well over 2 years!
Size: Medium, Style: 4 Pack, Size: Medium, Style: 4 Pack
These things are amazing! They last forever even with dogs that can destroy nearly everything else in mins! I ordered these as a doggie Xmas gift over TWO YEARS AGO, and they are still pretty much fully intact! They chew on them all the time, too!(see pics; that's over two years of steady use!) I only got the one 4 pack, and have 4 dogs, too! Since making them so well does kind of reduce my ability to buy many more from them, I feel I should at least let people know they really are crazy durable and dogs love them! I will prob buy another 4 pack soon, just so they are easier to find(end up under couches,etc). Def a good buy!!!!

Built for heavy chewers and actually holds up
Size: Medium, Style: Fishbone/Wishbone
This chew toy is a total win for heavy chewers and has held up really well compared to so many others we’ve tried. It keeps dogs busy for long stretches and they stay genuinely interested in it instead of destroying it in minutes. The shape makes it easy for them to grip and chew comfortably, which adds to how much they use it. The durability is the real standout here, making it one of those rare toys that actually earns a repurchase. The material feels sturdy, it’s easy to clean, and there’s no noticeable odor, which is always a plus.

Definitely recommend
Size: Large, Style: 4 Pack
My dogs absolutely love these! I bought them at a great price! They have lasted my dogs over a year! I have a full pitbull, pit/lab, pit/boxer, and a pit/mastiff. So needless to say they pass the power jaw test. They look just like the pictures and they are pretty light weight!

Benebone is fantastic for heavy chewers and busy, adolescent pups!
Size: Medium, Style: 4 Pack
This little multi-pack is cost-effective in a few ways, super durable and effective, and I'll definitely be purchasing the multi-pack again. We discovered these about a year ago and have been buying them ever since. I'm just now getting around to reviewing them because they're that good, plus I love that the company is family-owned. Four "bones" lasts a little over a month for a power chewer, which is a bargain! You get 4 medium size "bones" for the retail price of 2. These smell delicious to dogs but humans can detect the odor, which is so nice. They are incredibly durable, but somehow also not too hard for a power chewer, and they keep pup from chewing on books and other items that we don't wanted chewed to bits. Heavy chewers (and their people!) love these and the variety of shapes means we can swap them out in rotation and keep pup's interest going for a few weeks. Wait until your pup has all of their adult teeth, as they are a little too hard for teething. And for super power chewers, watch out for the fish shaped chew, as this one seems to allow larger pieces to be chewed off the fish head "corners" more easily due to the relative thinness of the shape at that point when compared to the other 3 shapes. Keep an eye on how much your power chewer is taking off of these "bones" (little tiny pieces do get chewed off) and toss them (or recycle with Benebone!) when your dog is able to chew off more than a crumb size piece. Hooray for Benebone! Hooray for family-owned businesses! We'll be back for more!

Seems Very Durable So Far
Size: Small, Style: 4 Pack
My dogs are really enjoying these chew toys! These keep them busy for hours!! So far they seem very durable and my little dogs can really chew and destroy so I’m happy about these so far! They rarely each chew a toy at the same time, but choose to take turns instead. But now they each have a chew toy and they are happy campers!!
