Ensure even application in order to achieve even growth reduction. Avoid overlapping sprays.

  • PRIMO 250 EC regulates turf growth and improves the quality of larger areas, economically. PRIMO 250 EC Turf Growth Regulator is the original, trusted and economical turf growth regulator for large areas that optimises the mowing effort and improves turf quality.

    Features

    • A versatile option for use on turf farms, bunker edges, roadsides and difficult to manage areas
    • Trusted EC formulation matches the uptake limits in turf to avoid phytotoxicity

    Benefits

    • Overall improvement of turf quality and colour
    • An effective growth and cost management tool through savings from reduced mowing time, clippings disposal and less machinery wear

    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.
