Knife is an iron formulation for using on lawns and ornamental plants. Iron is needed for chlorophyll production. Regular applications during the growing season produce a dark-green colour and consistent growth. Knife is intended for leaf application as a supplement to regular fertilising. KNIFE also contains extracts of ascophyllum nodosum to support plant health.
Knife should be applied as a fine spray mist. A water volume of 350 l per hectare should not be exceeded. For a successful application, it should not rain for 3-5 hours after application. Knife can be applied to correct the appearance of iron deficiency and for maintenance care. The application takes place during the growing season every 14 days with 5-6 l per hectare. In the case of acute iron deficiency, 6-8 l per hectare, every 7-10 days if necessary. Then continue with the normal application quantity.
