Threat from wheat bulb fly

WHEAT BULB fly poses the highest risk for many years this season, warns Dow Agrosciences.

Exceptionally high egg levels have been found in ADAS field testing in Cambs and Lincs. Of 20 fields tested, half exceeded the “high risk” of damage threshold of 2.5m eggs/ha, and four recorded over 5m eggs/ha – “very high risk”. Cold conditions over Christmas and more recent milder weather means there is a danger egg hatch could have started already, although no evidence had been seen yet.
