Phytoregulatory substance to limit vegetation and improve the coloring of floricultural plants in the greenhouse. It is applied by spraying foliage, early in the morning or late in the afternoon, when the foliage is dry and the greenhouse has cooled down. The foliage should not be wetted with water for at least 24 hours, after spraying. Do not apply to plants weak, suffering from food deficiency, lack of water, frost damage or nematodes. Higher doses are recommended for fast-growing varieties as well as conditions conducive to rapid plant growth. A small-scale trial is recommended before the application is done to a large extent.
