Recommended applications rates are designed to give approximately a 20 to 50% reduction in clipping yield over a 2 to 6 week period. Growth regulation begins 3 to 5 days after application. The amount of growth regulation achieved will vary between situations due to environmental conditions and lawn management practices. Therefore, application rates will need to be adjusted to match growing conditions, management practices and the amount of growth regulation required in each individual situation. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli class=\"MsoNormal\"\u003eEnhanced turf quality and colour with finer, denser growth\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eReduction of excessive leaf growth throughout summer – meaning less \u003cbr\u003emowing plus reduced clipping removal and less potential for scalping\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eRedirects the plants energy to the root system – treated turf grows a \u003cbr\u003estronger, deeper and more robust root system, improving the ability \u003cbr\u003eof your turf to utilise available water and nutrients\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003ePre-conditions your lawn for hot, stressful summers – better heat \u003cbr\u003estress tolerance, less wear and tear, and reduced watering needs\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003ePRIMO® HG can slow turf leaf growth for up to 4 weeks – so if you  \u003cbr\u003eare going on holiday, one application prior to leaving means that \u003cbr\u003eyour lawn doesn’t get out of control while you’re away\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eLow application rates of active ingredient\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eBacked by Syngenta\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eApplication Rate\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan\u003e4ml - 80ml in 10L of water per 100 square metres (with pressure sprayer)\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eDetails \u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eHow does PRIMO® HG work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003ePRIMO® HG is absorbed through the leaf and works by reducing the elongation (length and size) of stems, stolons and leaves in the above ground parts of the turf plant. The root system is not affected but does benefit from the efficiencies that result from reduction in excessive leaf\/ stem growth. PRIMO® HG has no root absorption, therefore targeting the foliage on application is critical for best results. The smaller leaves and shorter internodes on stolons result in much less physical upward growth and thus reduce mowing, clipping removal and plant injury.\u003cspan style=\"mso-ansi-language: EN-US;\" lang=\"EN-US\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIncreasing the amount of PRIMO® HG applied will increase the level of regulation applied.
