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.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

Great start to the series! Loved it!
Format: Kindle
I really liked this story! It pulled me in from beginning to end and was engaging. I started to feel for the characters very early on, especially Effie and Julian. I loved how Julian knew right away that Effie was his mate and that meant for his whole bonded pack. For Effie, she didn't realize it meant that Julian was her mate but she felt at home with him, something she hasn't really felt very much at all. I love that we get so many details within this story as things do happen in a short span of time but it doesn't feel rushed or like things happen on fast forward due to that level of detail that we get. It doesn't get bogged down either. I love how Effie has that instant connection with all of her mates, she doesn't fully understand it but she feels it and is going with it. Her mates are very protective of her and she feels safe and at home with them, a feeling that she really has felt as long as she can remember, since she doesn't remember but for the last few years. I loved seeing her build her relationships with her mates as a whole and individually as well. I love how she doesn't just count anything out with any of her mates, even seeing the tension between some of them. She feels comfortable with them and is working on finding her place and becoming more confident in that with each other them. She also has lots of questions regarding the university and how she got there but she also wants to learn and figure things out. I really enjoyed this one and it ends on a slight cliffhanger and I definitely want and need the next one as I am fully engaged and hooked with the characters and want to see them find their happy ending.

Effie girl
Format: Kindle
I really enjoyed this intro into a new shifter world. This is a university setting RH shifter book. We have 5 alpha males (4 wolves and 1 non wolf) all with their own problems but they all are instantly possessive and attentive towards our FMC Effie. This book takes place in the span of 3 days where a lot happens. I have a lot of thoughts. I really liked it yet I was also really frustrated at times with it. So here we go Pros: The 4 MC’s Tore, Dakota, Caedmon, and Julian are instantly possessive and all about Effie our FMC. I love this because lately all I’ve been seeing is the rejected mate story line and this is definitely NOT that. I love books where the alphas don’t have to be jerks and reject their women which ours don’t do. The men our all relatable in trying to work through some of there own issues while still caring and being attentive to Effie. They aren’t perfect knights in shinning armor but it’s clear they try hard to make her feel special and important to them. The writing is flawless and it was incredibly easy to continue reading (literally finished this book in one sitting) Cons: There was so much more inner monologue than actually dialogue between characters. Usually I don’t mine this but while reading it (on my kindle) the monologue had like 4 whole pages in between two sentences of dialogue here and there. It was just irritating not getting much actually conversation. (I was I think 12% in to this book before there was an actually dialogue. It was all Effies internal monologue or flash backs) The world building left a bit to be desired because I still have tons of questions mainly about the types of wolves but I understand this is part of the naivety store line but still This whole book takes place in the span of three days. No big ah ha action packed moments happened until the very last chapter. A lot of it was build up for the next 4 books I’m sure but it’s still frustrating because coming out of it I still feel like I know relatively nothing about this world. Each guy is a different species of wolf get we know nothing about any of them other than Fenrir wolves can’t shift. - 4.5 stars because I definitely will pick up the second book. Book 1 ended in a cliff hanger so I’m eager to see what happens. I hope we get a bit longer storyline though and allow it time to develop so we get more information over all. This is a good book and I definitely recommend giving it a try. It’s a good start to a new series.

wow!!
Format: Kindle
I mean I was losing interest when I first started to read the first few chapters but I was still caught in the underlining description of what life was like for Effie. Then once she left to go to the University I was wrapped around the story. Very emotional and gripping as I understood the characters better. I'm glad I ordered the second book because I think this is going to be a very compelling series. I must say I'm not good with angst. But miss Sinclair has a talented flair for storytelling. I'm invested now to see it through.

Absolutely Fantastic!
Format: Kindle
Once again M. Sinclair has created another masterpiece! This book was so unlike anything else I have read! It was such a unique twist on a shifter book that I was absolutely compelled from beginning to end. Effie made my heart all warm and fuzzy, she is just such a naturally kind person despite all of the things she has gone through. Her huge heart shines through in all she does. Then their are her mates...protective, caring, and possessive Effie’s mates are just as much attracted and attached as Effie is to them. Their bond is instantaneous and strong. Despite Effie not knowing what to make of it at first and seeing it as to good to be true, her mates take it in totally stride. I love the connections they have all built in such a short period of time. Effie brings a unique dynamic to this group. I am sitting at the edge of my seat waiting to see where this story goes. There are so many questions that that ending left and I genuinely cannot wait for more! I have grown super attached to these characters that more of their story can’t come soon enough!
