Agriculture | n. phr.

a disease caused by a fungus (Cycloconium oleaginum) that provokes a heavy defoliation, with the resulting weakening of the tree and a fall in its productivity, and which is characterized by the appearance of circular dark brown to black spots on the leaves" topside.

Example

Olive leaf spot is controlled by a copper-containing fungicide applied once in late fall before winter rains begin. A second application is of questionable value; if used, it must be applied before mid-January.

Additional information

if fruits fall off close to the harvest, they will produce low quality oils. The olive leaf spot can be avoided by keeping olive-trees clear and not excessively lush. It can be controlled with copper-based fungicides.
