Insectisides outlawed by EUby Malcolm Greenhalgh on 07/04/13
Some major insecticides are outlawed by the EU. We ought to be careful with insecticieds, as they kill essential insects, such as bees, as well as nasties; and if we us them stupidly (as perhaps described by one of our speakers) even more will be banned. So spray with insecticide late in the evening, when bees have gone home to roost. Also be sensible.
I spray my apple trees to prevent damage by codlin moth, but use the pheromone traps to tell me when to do it (we sell them in the hut) but up the trap(s) and when you see about a dozen moths trapped on the sticky cardbaord spray THAT EVENING. then give them another spray exactly 14 evenings latter.
