Fungicide with protective, therapeutic and antisporogenic action. Avoid continuous applications with the same formulation. After spraying with Amistar, follow operations with fungicides of a different mode of action. For example, alternating Amistar with fungicides that have Kresoxim methyl, famoxadone, fenamidone, picoxystrobin, pyraclostrobin, trifloxystrobin, fluoxastrobin, metominostrobin, orysastrobin, dimoxystrobin & enestroburin is not allowed. Amistar is phytotoxic in apple trees. Do not use it for applications on apple trees or when there is a possibility that the spraying cloud will reach a neighboring apple tree crop. In addition to preventive, operations with the formulation can be done as soon as the first symptoms appear.
