Managing foliar diseases in fodder beet
The substantial growth of fodder beet plantings has come with higher incidences of foliar diseases in the popular crop.
The leaves are a valuable protein source when fodder beet is fed to stock. Foliar diseases not only reduce the palatability of the leaves, but will reduce crop yields. Maintaining green leaf retention and quality maximises the protein feed potential of crops.
Escolta®, a new product from Bayer Crop Science this season, is a highly effective fungicide for the control of foliar diseases in fodder and sugar beet crops. A co-formulation of two active ingredients, Escolta controls the most common foliar diseases seen in New Zealand beet crops such as powdery mildew, beet rust, cercospora and ramularia leaf spots. Escolta, through controlling these diseases, maximises green leaf retention and provides physiological benefits that improve greening and yield.
Foliar diseases in beet crops usually start to appear when, or soon after the crop canopy closes in. The first Escolta application should be applied as soon as any disease is observed in the crop. The best results are seen when Escolta is used as disease first becomes active in the crop and before disease becomes established.
A second application can be applied 3 to 4 weeks later to maintain maximum length of protection. The use rate is 350 mL/ha with a maximum of two applications of Escolta allowed per season. Escolta can be applied as a ground or aerial application.
For ground application a water rate of 200 litres per hectare and for aerial application, 80 litres per hectare are recommended. Ensure good spray coverage of the crop leaves. The withholding period for Escolta is 42 days. Ensure that Escolta treated crops are not fed to stock until 42 days after the last application.
“Trials conducted in New Zealand have demonstrated the effectiveness of Escolta against rust and powdery mildew” says Lovisa Eriksson, Bayer Product Development Manager. “In the trials, two applications gave superior efficacy over a single application” adds Lovisa.
