Katana® can be applied using a knapsack or a vehicle mounted boom sprayer at a rate of 150g\/ha in 200-600l\/ha water.\u003c\/p\u003e\n\u003cp\u003eKatana® 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.\u003c\/p\u003e\n\u003ch3\u003eProduct Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCan reduce the number of herbicide applications that are necessary\u003c\/li\u003e\n\u003cli\u003eWorks for up to 5 months\u003c\/li\u003e\n\u003cli\u003eControls the emergence of both broadleaved and grass weeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eInstructions for use\u003c\/h3\u003e\n\u003ch4\u003eWhere to use\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eNatural surfaces not intended to bear vegetation - \u003ci\u003eAreas of soil or natural outcroppings of rock that are not intended to bear vegetation\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003ePermeable surfaces overlying soil - \u003ci\u003eAny man-made permeable surface (excluding railway ballast) that overlies soil and is not intended to bear vegetation\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003eHard surfaces (railway ballast only) - \u003ci\u003eAny railway ballast impermeable surface that is not intended to bear vegetation\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003eAmenity vegetation (around) - \u003ci\u003eAny areas of semi natural or ornamental vegetation, including trees (see product label for susceptible non-target plants)\u003c\/i\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhen to use\u003c\/h4\u003e\n\u003cp\u003eKatana® is most effective when it is applied in the early to late spring before weeds the have germinated.
