LIVESTOCK farmers faced with low stocks of winter feed could be increasing the threat to cereals from BYDV this autumn.
Extra sowings of catch crops like stubble turnips provide an extra source of inoculum if volunteer cereals and grasses are not controlled, warns Roger Allen of Cyanamid in south-west England.
With warm, moist soils speeding cereal emergence, growers need to be more careful than ever, he urges. Applying a herbicide/insecticide tank mix as soon as tramlines appear is his advice.
• East Anglian BYDV sprays may be needed from mid-October, after very early drilling, adds Neal Boughton of Protectacrop. He reckons 10% of wheat was drilled by mid-September.
