How to Control Anthracnose

  1. Remove and destroy any infected plants in your garden. For trees, prune out the dead wood and destroy the infected leaves.

What fungicide is used for anthracnose?

The most effective fungicides for control are the protective fungicides containing chlorothalonil e.g., Daconil), copper sprays containing copper diammonia diacetate (e.g., Liquicop), propiconazole (e.g., Banner Maxx II), and the systemic fungicide thiophanate-methyl (e.g., Cleary's 3336, for professional use only).

What are the symptoms of anthracnose?

Does anthracnose stay in soil?

Anthracnose spores can live in soil for three to nine months, even without an infected plant nearby. In the soil, spores travel and spread through the movement of water, such as morning dew, runoff, irrigation, or rainfall.

Can anthracnose kill trees?

In general, anthracnose diseases do not kill trees, but repeated infections can weaken trees to other problems. Some defoliation may occur, but refoliation with healthy leaves follows in warmer weather. Concentrate on boosting tree vitality, which promotes new growth.

What is the cause of anthracnose?

Anthracnose disease is induced by the fungus Colletotrichum lagenarium, and the characteristic symptoms include small, yellowish watery spots that enlarge rapidly to become brownish. Oblong lesions then develop on the stems often resulting in death of plants. On fruits, round black sunken cankers occur.

How is anthracnose transmitted?

Which fungicide can be used to treat black rot?
