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.

The amount of growth regulation achieved will vary between situations due to environmental conditions and lawn management practices.
