PATCHY crops in the east are now emerging well, dispelling earlier fears that some fields may need to be redrilled.
But the mystery remains how seed, some of which has been planted up to two months, survived in such numbers, said Newmarket-based AICC agronomist Travor Scarff.
"There was very little evidence of blue mould, which was one of our biggest worries. Ten years ago in very similar conditions, it was widespread and redrilling was common."
New seed dressings may have helped, he suggested. "Where used they seem to be more effective." Dry seed, some of only 13% moisture, may have prevented early mould attack, he added.
"It would have taken the seed a long time to have become damp enough for the mould to take hold."
