Primo Maxx II Turf Growth Regulator

Tips For Use

Restraints:

• Do not apply to turf recovering from wear, renovation or turf affected by disease, waterlogging or other stresses.
• Do not use where growth regulatory effects are likely following the application of a fungicide or any other material.
• Do not apply to turf going into or coming out of dormancy.
• Do not apply if rainfall is expected within 1 hour, and do not irrigate turf for at least 1 hour after application.
• Do not apply to Kentucky Bluegrass as damage may occur.
• For professional use only

General Instructions:

• Primo Maxx II should be applied to actively growing turf at least 6 hours before or after mowing. 
• Good mowing management leading up to application is required to achieve a good quality turf surface and to obtain the best results from Primo Maxx II.

Growth Regulation:

• The recommended use rates are designed to give approximately a 20 to 50% reduction in clippings over a 2 to 6-week period. 
• Full growth regulation by Primo Maxx II begins about 3 to 5 days after application. 
• In practice, the amount of growth regulation achieved will vary between situations due to environmental conditions and management practices. 
• To some extent, therefore, application rates will need to be adjusted to match growing conditions, management practices and the amount of growth regulation required by the turf manager.
• Repeat applications can be made as soon as turf resumes growth or more suppression is required.
• Areas treated with Primo Maxx II should continue to receive regular maintenance practices, including irrigation, fertilisation, and weed, disease and insect control when necessary, as recommended for quality turf.

Winter Grass (Poa annua) Management:

• Different grasses vary in their sensitivity to Primo Maxx II. 
• Since Poa annua is more sensitive to Primo Maxx II than Bent Grass, Primo Maxx II can be used to reduce the competitiveness of Poa annua in Bent Grass golf greens. 
• Primo Maxx II can be integrated into existing Poa annua control programs. 
• Low rates of Primo Maxx II (that provide growth suppression of Poa annua, but not Bent Grass) applied during peak growth periods may enable a slow transition in the golf green sward composition away from Poa annua and towards a higher percentage of Bent Grass.

Bahia Grass (Paspalum notatum) Management:

• Different grasses vary in their sensitivity to Primo Maxx II and Monument Liquid. 
• Bahia Grass is very sensitive to the combination, resulting in control of seedheads as well as vegetative growth suppression. 
• Apply the combination as soon as seedheads start to form or when it becomes a regular mowing intervention issue, normally from October to January. Apply at 4-week intervals after mowing.

Couch Overseeding:

• An application of Primo Maxx II to couch will enhance the establishment of cool season turf grasses. 
• Primo Maxx II is foliar absorbed, so germination and seedling growth are not affected. 
• Apply Primo Maxx before verticutting, scalping, spiking or other similar operations to the couch. 
• Apply Primo Maxx 1 to 5 days before seeding.

Mixing:

• Primo Maxx II is a soluble concentrate (SL) that mixes completely with water. 
• It may be tank mixed with many commonly used fungicides and liquid fertilisers. 
• Add the required quantity of Primo Maxx II directly to a spray tank containing 1/2 of the required spray volume. Add the rest of the water and ensure the mix is thoroughly agitated before and during application.

Application:

• Ensure even application to achieve even growth reduction. Avoid overlapping sprays.
• Application Volume: Apply in 100 to 500 L/ha water using suitable flat fan nozzles.
• Application volume should be adequate to ensure thorough and even coverage of the turf leaves and penetration to the crowns. 
• In higher-cut turf (≥15 mm) a significant spray shielding effect can occur, negatively impacting spray penetration and even coverage at low application volumes.

Knapsack:

• It is important to apply the correct quantity of Primo Maxx II to a known area of turf. 
• Apply between 2 and 10 L water/100 m2 turf. Preferably use flat fan nozzles and ensure even coverage is achieved.

Golf Courses and Bowling Greens:

• Ensure product placement as uniformly as possible onto leaves and into crowns.
• The ideal application volume should be 350 to 500 L/ha. 
• For best results, use medium to coarse droplet size with Syngenta XC025 or XC04 nozzles or equivalent nozzles.

All Other Turf Areas:

• Ensure product placement as uniformly as possible onto leaves and into crowns. 
• The ideal application volume should be 200 to 500 L/ha. 
• For best results use medium to coarse droplet size with Syngenta XC025 or XC04 nozzles or equivalent nozzle.

Bahia Grass Suppression and Seedhead Control:

• Ensure product placement as uniformly as possible onto leaves and into crowns. 
• The ideal application volume should be 200 to 500L/ha. 
• For best results use medium to coarse droplet size with Syngenta XC025 or XC04 nozzles or equivalent nozzle.

Non-ionic Surfactants:

• For Bahia Grass suppression and seedhead control when tank mixing with Monument Liquid, use Agral (600 g ai/L) at 0.42% v/v or 420 mL/100 L spray mix. 
• Use surfactants (1000 g ai/L formulations) at 0.25% v/v or 250 mL/100 L spray mix.

Application Near and Around Monuments and Hardscape Materials:

• Primo Maxx II, at normal dilution rates, will not stain brass, bronze, concrete, granite, marble or other types of stone. 
• Before using Primo Maxx II around other materials, test on a small-scale basis first.

Compatibility:

• Primo Maxx II is compatible with a range of commonly used fungicides, insecticides, herbicides, fertilisers and pigments. 
• Primo Maxx II can be tank mixed with Heritage® Maxx Turf Fungicide, Headway® Maxx Turf Fungicide, Posterity® Turf Fungicide, Instrata® Turf Fungicide, Medallion® Turf Fungicide, Subdue® Maxx Turf Fungicide, Velista® Turf Fungicide, Banner® Maxx Turf Fungicide, Daconil Weather Stik® Turf Fungicide, Casper® Turf Herbicide, Monument® Liquid Turf Herbicide, Adagor® Turf Nematicide And Miticide, Higran Turf Miticide. 
• As formulations of other manufacturers products are beyond the control of Syngenta, all mixtures should be tested prior to mixing commercial quantities.

Compatibility For Common Couch, Hybrid Couch and Kikuyu turfgrasses:

• Primo Maxx is compatible with some formulations of products containing the following chemicals: 2,4-D amine, bromoxynil, MCPA/bromoxynil/dicamba, MCPA ester/bromoxynil,
• MCPA ester/bromoxynil/dicamba, MCPP/2,4-D amine/dicamba or MCPP/dicamba.
• However, some transient discolouration of the treated turf may occur after the application of a tank mix.
• For the treatment of broadleaf weeds in turf with herbicides other than those indicated above, it is recommended to apply Primo Maxx and the broadleaf weed herbicides separately,  allowing at least 10 days between an application of Primo Maxx and the broadleaf weed herbicides.
