New from Bayer CropScience for 2015 is Redigo Pro seed treatment whichcontains tebuconazole and prothioconazole. The inclusion of tebuconazole inthis new product is designed to further improve the spectrum of control andactivity provided by Redigo (prothioconazole) and gives broad-spectrum diseasecontrol with consistent high levels against the major seed borne diseases, saysthe company. Formulation changes alsoresult in a good seed appearance and crop safety, it adds.
Trials have shown very high levels of control of diseases such as bunt(both seed and soil borne) and a doubling of establishment where Microdochiumnivale is present. Redigo Pro also reduced inoculum of Fusarium and subsequentmycotoxin production. It controls blue mould and will greatly reduce thegermination of treated ergot particles.
The recommended application rate is 0.5 litres/tonne on wheat and othersmall grain cereals except barley. The dose is increased to 0.67 litres/tonnefor barley or where high levels of Microdochium infection are present in theother cereals. However, while Redigo Pro can be used on barley, Raxil Star(fluopyram + prothioconazole + tebuconazole), a specialist product developedand tailored for the crop, is usually a more cost-effective option. Bothproducts can be used on spring and winter barley.
Also launched this season is straight Deter (clothianidin) which can beused alone or with Redigo Pro as an alternative to Redigo Deter (clothianidin +prothioconazole). It should be remembered that while clothianidin can be usedon both spring and winter cereals, treated crops must be sown before the 1stJanuary.
