One Hamlin tree with 10 infected fruit was found 1.5 miles east of a previously positive tree and 1.9 miles west of a positive tree in Hendry County, according to a Division of Plant Industry email.

As a result, the existing quarantine will be expanded by 1 square mile.

The second find also involved one Hamlin tree with 1 infected fruit was found in Collier County.

This find is 7.3 miles south, 4.8 miles east and 4.7 miles north of previously positive blocks.

The state has enacted a new 9-square-mile quarantine around the positive tree, affecting two citrus entities.

The positive trees and quarantines are within the current 10-mile survey buffer.

Delimiting surveys to determine whether the disease has spread outside the buffer continue.

Young fruit may become infected with the fungus during the spring. But symptoms typically don't appear until fall as harvest nears.

Citrus black spot causes unsightly blemishes on the surface of fruit, rendering it unmarketable for the fresh market. In severe cases, it can cause fruit drop.

It can be controlled with several registered fungicides.
