FORTRESS - control powdery mildew in sugar beet

Using Fortress* in sugar beet crops can provide growers with up to 8 weeks control of powdery mildew (Erysiphe betae).

Powdery mildew is one of the most devastating diseases that can hit sugar beet crops during the summer months. Early protection of the valuable sugar beet crop is essential to ensure losses from the fungal infection are minimised.

The infection can be identified by white/grey fungal mycelia and spore growth on the leaf surfaces. Over a period of time this fungal growth will turn the leaves yellow and cause them to die back - resulting in a reduction in green leaf area, sugar content and yield.

Fortress (quinoxyfen) can be used in sugar beet at 0.3 l/ha or, alternatively, as a split treatment of two applications at 0.2 l/ha. The sequential approach may be beneficial where high and sustained levels of powdery mildew are expected, where re-infestation is expected or where a later harvest is planned.

Fortress should be applied at the first sign of disease which is usually late July or early August. Where the split treatment is used, a further application can be made any time up to 28 days before harvest.

Using Fortress means you can benefit from a proven product that has a unique mode of action and can offer up to 8 weeks protection.
