Disease threat to forward silage crops


Italian ryegrass and Westerwolds silage crops are now well advanced, and may be ready for cutting three weeks ahead of schedule, due to the warm, mild winter which meant grass never really stopped growing.

While farmers will welcome the chance to fill their clamps early, the threat of disease attack is much higher than usual.

"Crown rust is favoured by high temperatures and is usually an end-of-season problem," says Rod Bonshor, general manager for Oliver Seeds.

"But most of the fields I walked at the end of last week across the Midlands had significant infestations on the lower leaves. Severe attacks can reduce grass yields by as much as 25% and are no longer restricted to the south of England. Cases have been reported in North Yorkshire and beyond."

Too late to spray
Affected crops can be sprayed with a propiconozole fungicide, but on rotational grassland require a 28-day interval from application to harvest. So it may be too late to spray the most forward crops.

"The only answer for some fields will be to harvest the crop as soon as conditions allow, and use an additive to restrict the growth of moulds on the conserved material," suggests Mr Bonshor.

"Farmers should leave a longish stubble – around 10cm, which will allow the grass to return to vegetative growth as quickly as possible, and apply nitrogen fertiliser promptly. This should resolve the disease issue in the subsequent crop. However, new growth should be checked to spot any signs of re-infestation."
