Types of Fungicide for Shrubs

Multiple organisms can cause plant disease. This includes viruses, nematodes, fungi, and bacteria. Fungicides are pesticides that can prevent, kill, mitigate or inhibit the growth of fungi on plants.

Internal vs External Fungicides

Contact fungicides (External) stick to shrub surfaces. And shrub plants can’t absorb them. They provide a protective barrier. As a result, fungus fails to enter and damage plant tissues.

Systemic products are also called Internal fungicides or penetrants. Shrubs can absorb them easily. Also, these pesticides can move from the site of application to other parts of the plant.

Preventive vs. Curative Fungicides

A preventive fungicide prevents fungus from getting into the plant. It must come into direct contact with the fungus. Hence, make sure you reapply it to new plant tissues. It may need reapplication when leaves or needles expand in the spring or if the product washes off.

On the other hand, curative fungicides target fungus after infection. This means they can stop the disease after the infection has started. You may opt for it once you notice the symptoms.

Both preventative and curative fungicides can move through the plant.
