Preventative, Curative and Eradicant Fungicide with Maximum Systemicity


Impact TM contains flutriafol, the world's most systemic azole fungicide for control of a wide range of diseases in many important crops.


Fast Action


Impact rapidly enters the plant giving immediate protection and stopping ongoing fungal attacks with its strong eradicant action.


Unique Systemicity


Indication of the fast movement of Impact into plants can be seen by the relative lipophilicity (Log Kow Values), the lower values moving fastest through the wax layers of plants.

To demonstrate the systemic action of Impact, Soyabean leaves (ref below) treated with a small spot of fungicide around the central vein, shows that tebuconazole (left) controls rust on the soyabean leaf where the fungicide has been applied. Impact (right) moves within the leaf to control the rust across the whole leaf area
