As above. NO flowers left so no risk to bees. Don't normally treat because of this and usually worse on headlands, but these are right through the crop now. Above 10% headland threshold but not there in yet in the centre of field. Plants with big colonies on are really suffering but I guess they are already a lost cause. Is it worth applying an insecticide (aphox?) or not? Likely to go through with second fungicide end of the week (teb plus amistar). Thanks
