Pests in Gardens and Landscapes

Rind stipple of grapefruit

During prolonged periods of cold, wet weather, the rind of grapefruit develops small, brownish pits. The pits often have concentric rings around them or they coalesce into larger, irregular lesions. If the fruit is injured while green, a green halo appears around the pits and persists until the fruit has turned yellow. The symptoms occur mostly on exposed fruit on the north side of the tree. The rind damage, which seems to affect only grapefruit, lowers the grade of the fruit.


No treatment is available.
