I have a Victoria Plum tree and have a lot of problems with maggots in the fruit. I hang out Growing Success Plum Maggot and Apple Maggot monitoring traps every year and on the packets it does say to treat with a suitable insecticide if necessary. Please can someone let me know what I can do to try to get any fruit which is not stung and what insecticide I can use? I can't find anything in the local garden centres which is for the purpose of eradicating these pests.
I have the same problem with my Victoria plum. One year I remembered to put grease bands around the trunk in late autumn; the following summer I had far less 'protein' in the fruit. Last year, I used the plum pheromone trap - waste of money!
I have bought some fruit tree grease which I am going to put around the trunk today. Rather late but better late than never. Shall see what happens this year. I really want to get a greengage tree but it seems a bit pointless at the moment!
The pheromone traps aren't for getting rid of the moths - you use them to monitor the number of moths around so that you know whether or not you need to treat for moths.

Hope that helps
