Sentinel is a highly effective broad-spectrum systemic foliar fungicide for the control of a wide range of leaf and stems diseases in cereals. Composed with the active ingredient Propiconazole and formulation of an emulsifiable concentrate is absorbed by the assimilating parts of the plant, the majority within one hour. It is transported upwards and acts on the fungal pathogen inside the plant at the stage of the first haustoria formation. It stops the development of fungi by interfering with the biosynthesis of sterols in cell membranes. The best results are achieved when the disease is in the early stage of development.
