Spring Wheat: Disease & Pest Update – June 2020

Diseases

T2 fungicide programmes in spring wheat do not need to be quite as robust as for the winter crops although broadly the same principles apply. Yellow rust and Septoria both need to be managed but because growth stages are more rapid then often a head and shoulders approach is all that is needed and optimal doses are lower than for the winter crop. The cost benefits of additional multisites are not as great as in the winter crop and are less commonly used.

Pests

Orange wheat blossom midge and saddle-gall midge can be a threat to spring wheat.  Varieties that are believed to be resistant to orange wheat blossom midge include Mulika, KWS Cochise and KWS Chilham,
