It seems to me that not allowing the plant to flower and re-spraying every three weeks would mean no flowers - certainly on the time-table of my roses!  The saw-fly were laying here from mid April to the third week of June this year.

I am not a great fan of RHS suggestions for using chemicals to deal with garden pests.

But I am still open to suggestions that do not use chemicals.

I am sorry, but you are wrong on that one.  A systemic insecticide works through a plant and kills when insects, etc, bite or otherwise damage a plant part.  Bees can sometimes pick it up when they go into a flower, as bees do.  They can then carry it back to the hive and eventually kill the whole hive. You don't have to actually spray the bee to damage it.  Humans need bees, so I won't use this type of killer.

Thanks, Alina.  I can't bring myself to spray with systemic insecticide as this will also ill many visiting bees and much more.  Guess I just have to live with it.  For the record, this year's roses look really good in mid June onwards!

I grow many shrub and climbing roses in my walled garden and have been troubled by leaf0rolling saw-fly for at least 3 years.  This is getting worse.  I have picked off leaves, looked after the soil beneath and exposed it to birds, used sticky traps, covered with netting and fed the roses extra to compensate for leaf loss.  Can anyone with experience of this pest give me any more ideas?
