In areas where oilseed rape is grown intensively a wide range of diseases infest this crop. The key diseases are Cylindrosporium spp., Phoma, Alternaria spp., and Sclerotinia sclerotiorum. Impact® effectively controls:

Leaf spot - Cylindrosporium spp.

Black leg - Phoma

Alternaria - Alternaria spp

Particularly good control of Cylindrosporium spp., Phoma, and Alternaria spp. is seen following treatment with flutriafol in a wide range of field trials conducted throughout Europe and Australia.

Impact®, like other triazole fungicides, is often applied in combination with benzimidazoles. Below the results of four trials are listed in which the control of Cylindrosporium spp. using Impact® in combination with carbendazim has been compared with other carbendazim mixtures.
