Controlling Existing Pathogenic Diseases

Diseases will inevitably appear in your garden one way or another, no matter how conscientious you are. It is a sad truth. However, there are several steps you can take to control the situation.

First and foremost, selectively remove the diseased portion(s) of the infected plant(s). Prune away infected branches by cutting back to the next healthy bud or branch collar. It the majority of the plant is infected it is best to remove the plant entirely and replace it with something more resistant to the particular disease. Dispose of or destroy the infected debris, and do not add it into compost.

Second, prevent the spread of the disease. Plant pathogens are easily transmitted in water so avoid working in the garden when the foliage and/or soil is wet. Also, disinfect your garden tools immediately after working with an infected plant, especially before moving on to another plant. This may be accomplished by dipping the tools into rubbing alcohol or a bleach solution (1 part bleach to 9 parts water.)
Weeds may contribute to disease problems as well by harboring disease-spreading insects and even the pathogen itself. Remove the weeds and you remove the risk and at the same time improve air circulation.

The most extreme method of control is chemical application. This should be a last resort when the disease is present in epidemic proportions threatening severe damage. Always follow the guidelines provided with the chemical and make certain it is labeled to treat the particular disease you need controlled.
