English: Bayer Crop Science display at the 2010 Cereals event, near to Chrishall Grange, England, Great Britain. Bayer making very visual statements about their new "Xpro" fungicide technology. Fungicides are critical to modern cereal growing, lush green wheat crops are at varying risks to the threat of many diseases such as brown and yellow rust, eyespot, mildew and septoria. To achieve good yields and as important clean whole grains of wheat then a programme of fungicide inputs must be used. Plant breeders try to select good disease resistant characteristics when breeding new varieties and these will last for a few years before new strains of disease evolve, so its an ongoing battle. The Cereals event is a trade showcase for arable farmers and associated industries. Displays of machinery, products, latest technologies and trial plots of cereals are all laid out on a temporary show ground that moves between different host farms around Cambridgeshire, Hertfordshire and next year Lincolnshire
