Wheat growers will need to be more vigilant about keeping disease control costs down this season following the banning of cheaper, older fungicides and the likely wider use of more expensive replacements.
They face the first season without the popular multisite chlorothalonil and the azole epoxiconazole which is banned from sale, while they will have a second season’s use of the new azole mefentrifluconazole (as in Revystar), which is very effective but is not cheap.
Although freezing weather in January and February has delayed the development of disease, yellow rust is being picked up in the East, and experts warn that septoria can be found in many crops.
