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

  • 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.

My favorite toothbrush for my fur babies!
Color: Pink (2-pack)
I think these brushes are the easiest way to brush your fur babies teeth. I can get into their mouths and really see in there and brush each tooth and make sure the tarter is off. They even assist by trying to bite the brush and I use toothpaste for dog and gently brush back and forth first the front teeth then the side teeth then the inside teeth and the top of the teeth then the inside of the bottom and top teeth and I end with the left inside top and bottom teeth. I use vanilla mint toothpaste for dogs because my dogs are allergic to proteins. Their teeth look so white and their vet comments that their teeth look so great and clean. She does want them of course to have their yearly cleaning but she said there is no rush because their teeth are so clean and she sees no dental disease. I make sure that I wash the brushes daily with soap and keep them open after use otherwise mold will grow on them if you shut them in the case they come in. My pups weigh 6 lbs and 7 lbs and are Maltese females. They cooperate fully with me brushing their teeth because I started when they were puppies and now they are one and two years old. These brushes are lightweight and not expensive at all. I usually buy several at a time to make sure I have clean ones on hand just like you would change a human toothbrush monthly. Each pup gets its own toothbrush and I label the case for each with a marker. I like these better than a regular toothbrush because it’s 360 degrees and the pup can chew on it without hurting themselves or the bristles coming off. Highly recommend!

Dog Approved - Highly Preferred Over Standard Toothbrush
Color: Neon (4-pack)
These pet finger tooth brushes work well for me and my dog. He most definitely tolerates these so much more than a standard tooth brush. I believe I am able to reach more of his teeth and that I'm more effective brushing with these than I am with a standard brush. I put one on each of my index fingers. This makes it easier to do each side and the top and bottom without having to twist and turn to reach everything. The size is just right for my index fingers. They are a little tight getting them on and I have found that wetting my finger and the inside of the finger brush makes it a lot easier to put them on. The bristles on the finger brushes are soft, yet they are durable enough to give some good scrub quality and gum massage. These are a good price for what you get. I purchased the four-pack at right about $16.00. I have gotten numerous uses so far out of the two that I have been using. I will definitely purchase these again when it is time.

Probably Best for Medium-Large Size Dogs
Color: Blue (2-pack)
This finger cot–style toothbrush works well and is a simple way to brush your dog’s teeth, especially if they’re not comfortable with a traditional toothbrush. The material is soft yet effective at cleaning, and it gives you good control while brushing. The only drawback is that it’s a little large for my miniature Dachshund’s mouth, making it somewhat difficult to reach all areas comfortably. It would probably be a better fit for medium or larger dogs. Even so, it gets the job done and is a good option for introducing dogs to regular dental care.

The easiest and best tooth brush!
Color: Pink (2-pack)
Ive tried several other dog tooth brushes for my 74 lbs Coonhound. This style and brand is the only one that is easy and works for us. It's easy to move your finger around and all sides of it have the cleaning nodules so no matter which way your finger turns, they are always touching her teeth. I like to try to open her mouth and get the inside of the mouth too. I loop my finger around her fangs. It is soft without harder parts so it doesn't make her pull away. This brush is perfect. It's a good quality and comes with a container for storage.

Total GAME CHANGER - incredibly effective toothbrush for dogs
Color: Clear (2-pack)
This silicon finger brush is incredibly easy to use - and so EFFECTIVE (more on that in the last paragraph this review). At first, it seemed a little hard to get on my finger but I simply got my finger wet first under the faucet and it slipped right on with virtually no effort. And once on, it's easy to take off but doesn't slip off accidentally when in use - so - perfect! Quick & simply to clean - rinses off in the sink in seconds, and ready to use the next time. And, my dog not only lets me clean her teeth - she actually like it (this from a dog who used to hate it when I would try to brush her teeth with a regular doggy toothbrush). This silicon "brush" is incredibly maneuverable - way more so than standard dog toothbrushes or regular finger brushes. So much so it makes it super easy to not only get those normally impossible to reach back molars - AND - even the back sides of the teeth! With a normal dog tooth brush (or finger brush) my dog's clamping down made that impossible. Now, it's not only possible - it's easy! Our dog's canine teeth had build-up but it was not until I pulled her gums back and looked at her back molars that I saw how bad things had gotten - and we have a young dog! Her back molars not only had build-up but some appeared to be stained a tea colored brown that did not come off with my fingernail. It was pretty disheartening and I felt terrible. How could this happen so quickly? The vet said it was plaque (and not yet tartar) and that it wasn't bad enough to warrant a professional cleaning - yet - but that I needed to do a better job brushing. He said: "I can see exactly where your brushing stops" (referring to the condition on the back molars which I had not been able to do with a regular brush as my dog just wasn't having it). Tips: here's what's working for us. Instead of squeezing out a pea sized blog of tooth paste onto this brush, I put a tiny dab - that it's - on the very tip of the brush and focus my efforts on two of our dog's worst teeth on one side - on top and then on the bottom. Then I put another small dab and repeat on the other side of her mouth with 4 teeth on that side. Then, I use another small dab and focus work on another group of teeth. All totaled, I'm using maybe 4 to 6 very small dabs of dog toothpaste, probably half the size of pea collectively, perhaps less. That's it. However much you choose to use is up to you - be sure and use an amount that's safe and effective for your dog. Effectiveness: this works and it works well! In just 3 days using the same vanilla flavored enzymatic toothpaste by CET I was seeing improvement. By day 7, that improvement was so obvious I was actually surprised by how much better they looked. It's now been a little over two weeks and they are looking considerably better! Conservatively, I'm thinking a 50% improvement. Not bad for just 2 weeks, right? I'm actually think I'm going to be able to completely reverse things - we'll see. I'll try and update this review again in a few weeks and let you know how it's looking but in the meantime, I am absolutely thrilled with this brush. I paid $16 and it came 2 in a pack) and the first (and only one) I've been using still looks brand new after it's rinsed off. All in all - this brush is a game changer! I can now brush our dogs back teeth and even the back sides of her teeth, all in less than a couple minutes a day.
