Any advice on stopping maggots in apples ? I've tried greasebands & as a last resort, systemic spray, but no success

I assume you are afflicted with codling moth?

As Peter suggests, you probably mean codling moth.

Greasebands have no effect on codling moth - they are used to prevent winter moth (female are wingless)from climbing the tree. Winter moth eats leaves and petals - not fruit.

Spraying (in june-july more than once) can be a hit and miss affair too, as timing is crucial. Pheromone traps are available. Generally they are used to monitor codling moth frequency, so as to predict when to spray. Though, traps can help reduce attacks to an acceptable level - this is more easily done with a small amount of dwarf trees in the garden than old standards in an orchard. Also, remove all old fruit which may contain overwintering larvae.

Hi Mole,
I should like to reinforce your last sentence that it is vital to collect up all old fallen fruits and dispose of them sensibly. A lot of compost-conscious people put them on the compost heap which when you look at it is daft because all you are doing is giving the bugs a lovely warm winter holiday.

So not an easy task then, I was hoping it would be as the apples from the greengrocers are always maggot free.

theres only one thing worse than finding a maggot when you bite into an apple, ......


finding only half a maggot :D


this year we have very few apples at all, most years we have so many that we dont bother about a few with maggots so dont practice any sort of prevention.

Try this article

http://news.bbc.co.uk/1/hi/uk/262225.stm

It says the average pear is sprayed more than 13 times, and apples 16 times, often with a mixture of chemicals

More relavent to growing yourself, here is a link to a good website.- Very pragmatic - you will approve Johnboy!
