New products New productsSeveral new mildew products are now available, offering a wide range of modes of action against this increasingly problematic disease. The most recent active ingredients include proquinazid (Talius) and cyflufenamid (Cyflamid) both of which give mainly protectant activity. Where mildew is established such products need to be mixed with another active ingredient which has some curative activity such as Tern. The table below shows the activity of mildew fungicides currently available. | Chemical group | Active ingredient | Example products | Mildew activity | | Amidoxine | cyflufenamid | Cyflamid | (***) | | Anilinopyrimidine | cyprodinil | Unix | ** | | Benzophenone | metrafenone | Flexity | **** | | Morpholine | fenpropidin | Tern | *** | | | fenpropimorph | Corbel | ** | | Quinolene | quinoxyfen | Fortress | *** | | Quinazolinone | proquinazid | Talius | (****) | | Spiroketalamine | spiroxamine | Torch Extra | ** |

Product development 2005 2005 saw the launch of a number of new products that include three completely new active ingredients for use on wheat (boscalid, fluoxastrobin and prothioconazole). The list below shows the main products based on these three new actives.
Product name | Active ingredients | Comments | Fandango | prothioconazole + fluoxastrobin | Mixture of new azole from Bayer CropScience with new strobilurin. The azole prothioconazole offers a high level of septoria control but with additional control of stem base diseases including eyespot, sharp eyespot and Fusarium. Ideally positioned at the T1 timing for septoria and stem-base disease control. The fluoxastrobin also gives take-all suppression as well as controlling a range of other foliar diseases plus greening effects typical of strobs. | Helix | prothioconazole + spiroxamine | The addition of spiroxamine adds additional mildew and rust control to the straight prothioconazole. | Proline | prothioconazole | New azole from Bayer CropScience, highly active against septoria, both as eradicant and as a curative fungicide. Also controls other foliar diseases and stem-base diseases. Slightly weaker on rusts. | Prosaro | prothioconazole + tebuconazole | Mixture of 2 azoles. The addition of tebuconazole strengthens the activity against rusts. High total dose of azoles offers high level of foliar disease control. | Tracker | epoxiconazole+ boscalid | New active ingredient boscalid, from BASF, adds to septoria control of epoxiconazole. Boscalid is particularly active as a protectant fungicide. Hence no need to add chlorothalonil to ready-formulated product. Boscalid also adds to control of eyespot, sharp eyespot and Fusarium. Tracker is ideally positioned at the T1 timing for control of septoria and stem-base diseases. Controls wide range of other foliar diseases. |
