Pacaya is a residual herbicide for pre-emergent application. 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 150 g/ha.
|Formulation||Water dispersible granule|
|Areas of Use||Natural surfaces not intended to bear vegetation, permeable surfaces overlying soil, hard surfaces (railway ballast only), amenity vegetation (around)|
|Mode of Action Group||Inhibition of ALS|
Pacaya is a long-lasting residual herbicide which remains active on surfaces it is applied to for up to 5 months. Pacaya 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.
Pacaya has a limited effect on very young weeds but in general should be tank mixed with glyphosate for effective post-emergence as well as the long-lasting residual activity of Pacaya.
For best results the surface should be left undisturbed after application to ensure that the barrier effect created by Pacaya remains active.
This 50 g bottle is sufficient to treat 1 ha for up to 5 months.
Pacaya gives pre-emergence control by forming a surface barrier that prevents germination of a wide range of broad-leaved and grass weeds.
*A limited number of weed species are not effectively controlled by Pacaya (see label for further details).

When to use
Pacaya is most effective when it is applied in the early to late spring before weeds the have germinated.

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.
