Welcome to the FRAG-UK interactive search facility
Fungicides continue to play a key role in strategies for the control of diseases in crops, and the development of resistance in the target pathogens is a continuing risk. Resistance occurs when a pathogen becomes so insensitive to a fungicide that the fungicide's field performance is diminished, in some cases to the point where it could be completely ineffective.
There are a number of strategies that can be used to minimise the risk of resistance developing. These include applying the most appropriate products at the right time and at an appropriate rate. It is also important to make full use of effective fungicides with different modes of action in mixtures or as alternate sprays and to avoid repeated use of the same product or mode of action.
The following search facility will generate information on which fungicide groups and modes of action are approved for a selected crop, to assist the user in identifying fungicides from different groups which could be used in spray programmes for anti-resistance management. Codes and comments courtesy of FRAC. Chemical groupings follow classification as used in the Pesticide Manual 14th Edition.
For more information on different modes of action, click the mode of action codes on the output screen.
Please select your crop or choose "All crops" and await your output:
