Katana® is a residual herbicide containing  25% w/w flazasulfuron. It can be used to prevent emergence of broad leaved and grass weeds on natural and permeable surfaces as well as on railway ballast and around amenity vegetation. Katana® can be applied using a knapsack or a vehicle mounted boom sprayer at a rate of 150g/ha in 200-600l/ha water.

Katana® is an ideal choice for areas where the presence of weeds is not desirable, for example on play areas, mowing margins and shrub beds. Its long residual activity of up to five months means that the number of herbicide applications can be reduced with no loss of efficacy. Where weeds are already present Katana® can be tank mixed with glyphosate to provide a cost effective method of controlling existing weeds and preventing emergence of new weeds.

Product Benefits

• Can reduce the number of herbicide applications that are necessary
• Works for up to 5 months
• Controls the emergence of both broadleaved 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

• 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 1m (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.
