Only one other product with an ALS-inhibitor mode of action can be applied to a cereal crop treated with florasulam.

When florasulam is applied in sequence or tank mix with other ALS-inhibitor products there are no additional following crop restrictions or cultivation requirements over and above those stipulated on either product label EXCEPT when the sequence or tank mix includes Presite SX, Finish SX or Harmony M SX then ONLY CEREALS OR GRASS CAN BE SOWN IN THE FOLLOWING AUTUMN. All permitted label crops can be sown the following spring.

Can Dursban* WG be applied in tank mix with earwash fungicides?

Dow AgroSciences have tested the physical and biological compatibility of Dursban WG with a number of fungicides popularly used as earwash treatments. However, if applications of Dursban WG are made to control Wheat Blossom midge, tank mixes with earwash fungicides should not be made if the correct application timing for one or both products will be compromised. The following fungicides have been successfully tested for physical and biological compatibility when applied to winter wheat at GS 51-59.

Metconazole
Metconazole with azoxystrobin
Metconazole with famoxadone + flusilazole
Metconazole with pyraclostrobin
Metconazole with trifloxystrobin
Tebuconazole
Tebuconazole with azoxystrobin
Tebuconazole with pyraclostrobin
Tebuconazole with trifloxystrobin

For more detailed information about Wheat Blossom midge and the appropriate use of Dursban WG, please refer to the Wheat Blossom Midge pages.
