Jane, it's called citrus greening. Because the fruit does not ripen and stays green.
Lakeview is related to citrus - orange jasmine - Murraya.

It's spread by Diaphorina citri, citrus psyllid.

It's not the spraying. All host plants have to be grow under screen to keep the insects out.

Florida has had it since 1998, but it was only recently discovered that Murraya was a host for not just the insect, but also for the disease.

There's no cure BTW, and nothing yet available for the home grower to spray with.

Ah! What a shame... I certainly hope that someone can come up with a remedy.
