Group 15 Herbicide

ProForce Array 500 SC Herbicide is a pre and postemergent herbicide containing 500g/L of the active ingredient Ethofumesate. It is registered for the pre-emergent control of Wintergrass in a variety of turfgrasses including Bentgrass, Kentucky Bluegrass, Kikuyu, Queensland Blue Couch and Ryegrass. ProForce Array 500 SC is also registered for the control of a range of grass and broadleaf weed species in noncrop situations including fencelines and tree plantations.

Key Features

• Pre and Post-emergent activity. Ultimate application versatility. Array can be used prior to, at or after, following weed germination.
• Excellent safety on cool season turfgrasses as well as Kikuyu and Qld Blue Couch. Very safe to key turfgrass species that Array is labelled to be used on.
• Unique mode of action Group. Excellent rotational tool from a resistance management perspective.
• Flexibility around re-seeding of cool season grasses. Excellent safety around overseeding cool season grasses, particularly Ryegrass.
• Also registered for use in non-crop situations. Can be a useful rotational option for fenceline management or tree plantations as specified on the label.
• Has activity on difficult to control weeds including Barley Grass and Brome Grass. Provides versatility on a range of weed species.

Maximising Performance:

Turfgrass Selectivity

Perennial ryegrass is considered to be the safest turfgrass to Array (ethofumesate) treatments. Previous research conducted has determined plant safety to ethofumesate in the descending order of tolerance as below:

> Perennial ryegrass > Tall fescue > Creeping bentgrass > Kentucky bluegrass > Wintergrass. (Adams, 1989)

Array is also safe for use on Kikuyu and Qld Blue Couch turf species.

Array is NOT SAFE on Couch and Hybrid Couch turf surfaces. 

Soil Residual Activity

Array has been shown not to leach in soils that have an organic matter content greater than 1%. Soil microorganisms are responsible for the degradation of ethofumesate in soils. The soil persistence of ethofumesate is affected by climate, soil type and microbial activity. Under warm, moist conditions and cold, dry conditions the half-life of ethofumesate is 5 and 14 weeks, respectively.

Weeds Controlled

BROADLEAF WEEDS

• Chickweed (Stellaria media)
  
• Cleavers (Galium aparine)
  
• Fat-hen (Chenopodium album)
  
• Fumitory (Fumaria officinalis)
  
• Redshank (Amaranthus retroflexus)
  
• Shepherd’s Purse (Capsella bursa-pastoris)
  
• Storksbill (Erodium spp.)
  
• Clovers (Trifolium spp.)
  
• Cruciferous Weeds (Brassicaceae family)
  
• Patterson’s Curse (Echium plantagineum)

GRASSY WEEDS

• Barley Grass (Hordeum leporinum)
  
• Prairie Grass (Bromus catharticus)
  
• Summer Grass (Digitaria sanguinalis)
  
• Winter Grass (Poa annua)
  
• Wireweed (Polygonum aviculare)
  
• Brome Grass (Bromus spp.)

These weeds are controlled in beet crops, oilseed poppy, onions, ryegrass pastures, non-crop areas, and turf when ProForce Array 500 SC is applied as directed on the label.

Mode of Action

Ethofumesate, the active ingredient in ProForce Array 500 SC Herbicide is absorbed by young shoots and roots of susceptible weed species. The post emergence activity of ethofumesate is limited to very young weeds at lower use rates, as ethofumesate is not absorbed by leaves after the plant has produced a mature cuticle. Ethofumesate is translocated within the plant following coleoptile or root absorption but is not translocated out of treated leaves. Ethofumesate is believed to inhibit photosynthesis and respiration within the susceptible weed species.
