MARVEL® ULTRA PRODUCT OVERVIEW 3 What is Marvel® Ultra 120 ME MARVEL® ULTRA 120 ME is a plant growth regulator formulation containing 120 g/L of the active ingredient Trinexapac ethyl. MARVEL® ULTRA 120 ME is a micro-emulsion formulation possessing a patented, unique emulsification package which enhances product stability, improves rainfastness, spread, coverage and movement of trinexapac ethyl into the plant. MARVEL® ULTRA 120 ME is a global formulation sold by Adama / Quali-Pro in key turf markets such as the United States, Canada, SE Asia and now Australia. It is marketed as T-Nex in these countries. MARVEL® ULTRA 120 ME is registered for the regulation of leaf and stem growth, as well as a turf management aid across a range of turfgrass species and growing regimes. MARVEL® ULTRA 120 ME is also registered for the suppression of Bahiagrass and seedhead control in combination with herbicides. MARVEL® ULTRA 120 ME is registered and safe for use on a very broad range of turfgrass species including; Zoysia, Fescues, Perennial Ryegrass, Durban grass and Poa annua. Marvel® Ultra 120 ME Mode of Action The active ingredient in MARVEL® ULTRA 120 ME, Trinexapac-ethyl inhibits gibberellic acid biosynthesis late in the pathway. This results in a significant reduction in cellular elongation and internode length. After application, new growth has shortened internodes, more tillers, and reduced vertical growth compared to untreated turf. Trinexapac-ethyl is rapidly absorbed by the plant’s leaves and crowns. The majority of uptake occurs within one hour of treatment. Absorption through roots is negligible, as the product is broken down in the soil environment quickly. MARVEL® ULTRA 120 ME is transported acropetally (upwards) in the xylem to the meristem, where cell elongation occurs. The systemic translocation properties of MARVEL® ULTRA 120 ME ensures even distribution of the active ingredient within the plant tissue. Full growth regulation with MARVEL® ULTRA 120 ME begins within 3-5 days of application. Key Features and Benefits of Marvel® Ultra 120 ME • Inhibits vertical shoot growth • Promotes rich colour, lateral stem and root mass development • Helps produce healthy, durable blades in turfgrass • Helps turf withstand seasonal stresses • Odourless, micro-emulsion concentrate, that is petroleum solvent free and tank mix flexible • Rainfast in 3 hours • Increases quality of final cut, particularly in high maintenance situations • Reduced clippings for efficient mowing and reduction in waste • Registered for use in Bahiagrass management and suppression • Registered for a very broad range of turf species (more than 11 differing turf species) • Proven and trusted formulation. Global formulation sold by Quali-Pro / Adama in many countries, including the USA & Canada. [Image of Marvel Ultra 120 ME container] 4 Simply. Grow. Together.

Bentgrass Field Trial Data with Marvel® Ultra 120 ME v Primo Maxx. Results of US University Field trials in 2006 have shown that MARVEL® ULTRA 120 ME (marketed as T-Nex in US) performs at least equivalently on Creeping bentgrass (Agrostis stolonifera) turf species to the industry standard, Primo MAXX formulation. [Chart: Quali-Pro MARVEL® ULTRA 120 ME vs. PRIMO MAXX® on Creeping Bentgrass, Purdue University 2006. Shows clipping yield over time for Untreated, Primo Maxx, and Quali-Pro MARVEL® ULTRA 120 ME.] Bahiagrass Suppression and Seedhead Control Bahiagrass is a difficult to control perennial grass weed, that in eastern Qld, eastern NSW, coastal districts of Southern Victoria and Western Australia has become problematic for turf managers. When applied in the spring and summer months in combination with suitable herbicides, MARVEL® ULTRA 120 ME can be effective in reducing Bahiagrass spread and seedhead development. To maximise performance, MARVEL® ULTRA 120 ME must be placed as uniformly as possible onto leaves and into the crowns of the Bahiagrass plant. Ideal application volumes should be 200 to 500 L/ ha. For best control it is recommended to use coarse nozzles - Turbo Teejet* or AIXR Teejet* (11004 or 11005) nozzles, at 8 km/h and 3 bar pressure. Boom height should not exceed 50 cm above the ground. To ensure adequate control is achieved, the combination of MARVEL® ULTRA 120 ME and the suitable herbicide should be tank mixed with a non ionic surfactant such as Wetspray 1000 at the rate of 250 mL/100 L of water. MARVEL® ULTRA PRODUCT OVERVIEW 5 Australian Field Trial Data with Marvel® Ultra 120 ME Results of Australian Field trials have shown that MARVEL® ULTRA 120 ME performs at least equivalently on multiple turf species to the industry standard, Primo MAXX formulation.

Marvel® 120 ME – Key Application Information The rates recommended on the label are designed to give approximately a 20 - 50% reduction in clippings over a 2 to 6 week period. In practice, the amount of growth regulation achieved will vary due to environmental conditions and turf management regimes. As a result, it is likely that application rates will need adjustment to match growing conditions, management practices and the quantity of growth regulation required. Repeat applications can be made as soon as turf resumes growth or more suppression is desired. MARVEL® ULTRA 120 ME growth regulator should be applied to actively growing turf, at least 6 hours before or after mowing. Good mowing practices prior to application are required to maximise performance and achieve quality turf swards. Use the lower label rate in situations when turf is going dormant due to high or low temperatures, or lack of moisture.
