Nectarine Scale?

[Mani]

Working for a customer today, her Nectarine tree which is growing in a large glasshouse has someking of scale, but not Pulvinaria regalis, does anyone know what kind of scale it might be? The adult female scale looks twice as small as your avarage Pulvinaria regalis scale and its orangey in colour with a smooth surface.

Massive guess - but might be Coccus hesperidum??

 

Here's some shots of some I found last year...

Bigger than that, about half the size of your average ladybird and only on the thin stems near the leafs. The leafs had black areas on them - honeydew?

 

What would you spray the tree with and when? Is it when they are at the crawler stage?

Spray with Scotts Bug Clear Ultra it will kill the scale insects, the black areas will be sooty mould, once the scale insects are all gone spray leaves with fungicide, the bills in the post lol

You could always try biological control, personaly my favorite choice, try one of these ''Metaphycus helvolus'' these little chaps will eat there way through the scale insects in no time, they are available from these people http://www.interiorlandscaping.co.uk/Biologica.htm
