So in your case you would define something like this in your Tree
model:
var $virtualFields = array(
'name' => 'CONCAT(Tree.cultivar, "-", Tree.stage)'
);
Then in your find:
$crop = $this->Tree->find('list', array('fields' => array('id',
'name')));
However you can further simplify your query because id and name are
defaults for find('list')
$crop = $this->Tree->find('list');
Have fun,
Nick
