NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION
WITHHOLDING PERIOD DO NOT GRAZE TREATED TURF/LAWN, OR FEED TURF/LAWN CLIPPINGS FROM ANY TREATED AREA TO POULTRY OR LIVESTOCK
GENERAL INSTRUCTIONS PRIMO 250 EC 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 250 EC.
Growth Regulation The recommended use rates are designed to give approximately a 50% reduction in clippings over a 4 to 6 week period. 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.
Poa annua Management Different grasses vary in their sensitivity to PRIMO 250 EC. Since Poa annua is more sensitive to PRIMO 250 EC than Bent Grass, PRIMO 250 EC can be used to reduce the competitiveness of Poa annua in Bent Grass golf greens. PRIMO 250 EC can be integrated into existing Poa annua control programs. Low rates of PRIMO 250 EC (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 250 EC 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 during October to January. Apply at 4 week intervals after mowing.
Mixing Add the required quantity of PRIMO 250 EC directly to a spray tank containing two thirds of the required spray volume. Add the rest of the water and ensure the mix is thoroughly agitated before application. PRIMO 250 EC can be tank mixed with Monument Liquid.
Application Ensure even application in order 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, impacting negatively on spray penetration and even coverage at low application volumes. Knapsack: It is important to apply the correct quantity of PRIMO 250 EC to a known area of turf. Apply between 2 and 10 L water/100 m² of turf. Preferably use flat fan nozzles and ensure even coverage is achieved. Golf Course Greens: Ensure product placement as uniformly as possible onto leaves and into crowns. Ideal application volume should be 350 to 500 L/ha. For best results use medium [XR Teejet* (11004 or 11005)] to coarse [Turbo Teejet* or AIXR Teejet* (11004 or 11005)] nozzles, at 5 km/h and 3 bar pressure. Boom height should not exceed 50 cm above the ground. All Other Turf Areas: Ensure product placement as uniformly as possible onto leaves and into crowns. Ideal application volume should be 200 to 500 L/ha. For best results use medium [XR Teejet (11004 to 11008)] to coarse [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. Bahia Grass Suppression and Seedhead Control: Ensure product placement as uniformly as possible onto leaves and into crowns. Ideal application volume should be 200 to 500 L/ha. For best results use coarse [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. 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. Alternatively use other quality non-ionic surfactants (1000 g ai/L formulations) at 0.25% v/v or 250 mL/100 L spray mix.
Compatibility For common couch, hybrid couch and kikuyu turfgrasses only: PRIMO 250 EC 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 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 250 EC and the broadleaf weed herbicides separately, allowing at least 10 days between an application of PRIMO 250 EC and the broadleaf weed herbicides.
PRECAUTION Re-Entry Period DO NOT enter treated areas without protective clothing until spray has dried. DO NOT allow the public to enter treated areas until spray has dried.
PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT Dangerous to fish larvae and oysters. DO NOT contaminate dams, rivers, streams or storm water drains with concentrate or used container. Wash spraying equipment and mixing and measuring utensils with water on grass.
STORAGE AND DISPOSAL Store in the closed, original container in a cool, well ventilated area. DO NOT store for prolonged periods in direct sunlight. Triple or preferably pressure rinse containers before disposal. Add rinsings to the spray tank. DO NOT dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, vegetation and tree roots. Empty containers and product should not be burnt.
SAFETY DIRECTIONS Will irritate the eyes and skin. Repeated exposure may cause allergic disorders. Avoid contact with the eyes and skin. When opening the container and preparing spray wear: • cotton overalls buttoned to the neck and wrist (or equivalent clothing) • elbow-length PVC gloves Wash hands after use. After each day's use, wash gloves and contaminated clothing.
