In rare cases of severe infection where the size and value of plants make it practical, applications of fungicides may be helpful. Generally fungicidal control is warranted if:
Repeated defoliations occur in one year or subsequent years

The plant is under stress
The plant is in decline
The plant is a needled evergreen
The disease is black spot of roses.

Sprays will not cure the infection but protect leaves from becoming infected.

To be effective fungicidal sprays must be begun at bud break before symptoms are noted and be continued at intervals specified by the label (usually 10 to 14 days) through the period of spring rains

Spraying after infection is present will provide little benefit. Recommendations will vary with the disease and fungicide used.

It is always good practice to have the disease identified before purchasing a control product. See table 1 for a general listing of active ingredients listed for control of various leaf spotting fungi.

Some people say that the black dots are actually tiny insect eggs. The best way to avoid this is to Water the plant from the top that is like how you wash a vehicle just splash water over the plant. This is the method I use to avoid worms and insects to lay eggs.

5. Last but not least you can still replace the plant.

For plants that chronically are plagued by leaf spots, gardeners find it more convenient to replace a plant with a different species or a variety that is more resistant or tolerant of disease.

A nursery can help you in your selection.
