Kult Plant Growth Regulator 1L | Wintergrass Suppression & Turf Growth Control

PRODUCT DESCRIPTION

Kult Plant Growth Regulator is a systemic PGR containing 250 g/L Paclobutrazol, used by turf managers and home gardeners across Australia to suppress Wintergrass (Poa annua), regulate vertical turf growth, and reduce trimming frequency on hedging plants.

Kult works by reducing internode lengths of new shoots. It slows vertical growth while allowing desirable turf species to dominate over time and keeping hedges in shape for longer between cuts.

Key Features

• Suppresses and controls Wintergrass (Poa annua) in turf
• Reduces vertical turf growth for a denser, more uniform finish
• Enhanced greening and improved turf quality
• Reduces trimming frequency on common Australian hedging species
• Suitable for Bentgrass, Perennial Ryegrass, Kentucky Bluegrass and Green Couch
• Systemic formulation - absorbed and translocated through the plant
• Suspension concentrate - mix with water and apply by pressure sprayer or watering can

Turfgrass - Application Rates

Apply to dry or wet turf and water in immediately with 4–6mm of irrigation. Apply using a boom sprayer with flat fan nozzle

How Kult Works on Wintergrass

Wintergrass suppression begins 1–2 weeks after application. At higher rates, Poa annua will yellow and its growth will slow or stop, allowing your desirable turf species to fill in the gaps. For best results, apply 1–2 weeks before Poa annua seed-head emergence to reduce seed-head visibility.

Important: Areas with greater than 70% Poa annua content will experience widespread discolouration. Reduce Poa annua content below 70% before applying at suppression rates.

Hedging Plants — Application Rates

Kult is registered for use on a range of common Australian hedging species, reducing trimming frequency once your hedge has reached its desired height and density.

Apply in late winter to early spring at the start of a new season's flush of growth. Apply to the root system adjacent to the stem at ground level. Remove mulch first to ensure the product reaches the soil. Light irrigation after application is recommended.

Critical Notes for Hedging:

• Do not apply to hedges less than 0.3m or greater than 2m in height
• Do not prune until 4–6 weeks after application as apical growing points must remain intact
• Do not apply to newly planted or recently transplanted hedging species
• Do not repeat treat within 12 months
• Always use the lower rate when applying for the first time
• Do not allow plants to experience drought stress just before or after application

Restraints - Do Not Apply When:

• Daytime temperatures are consistently above 32°C
• Soils are waterlogged or saturated
• Turf has been thinned by disease, insect damage, aeration or scarifying. In these situations wait until full recovery
• Turf has been recently over-seeded. Wait until establishment, then use lower rates only
