Prevention and Treatment of Spring Diseases in Trees

Yesterday I posted about common and deadly diseases that usually occur in your trees during the spring.

Two diseases that I focused on are Antracnose and Fireblight. Today I will tell how to prevent and treat Antracnose. Check in tomorrow for more information on Fireblight.

Anthacnose is similar in appearance to another plant fungus---blackspot---anthracnose is a disease that can harm or even kill a plant if left untreated. It can be found on many plants, grasses and even trees, although it is most noticeable and prevalent on tender-leafed rose bushes and climbing roses. Swift action is necessary when the weather turns humid and both organic and chemical-based methods should be explored to prevent an infestation of anthracnose

It is important to treat anthracnose as effectively as possible. Here are few treatments to get you started.

Organic Treatments
During the dormant season, you may be able to mix an application of lime sulfur and use that on the soil surrounding the plant. Lime sulfur is effective in preventing other fungus problems as well. Copper products such as Bordeaux are recommended and may be successful in preventing an anthracnose invasion. Neem oil may help prevent both anthracnose as well as other diseases and insects; purchase a strong Neem oil solution, at least 70 percent, and spray plants regularly for one to two weeks.

To Treat with Fungicides
Many systemic and spray fungicides are effective in prevention and treatment of anthracnose. Ask your local nursery about using "Chlorothalonil" under the brand name Daconil, "Maneb" under the brand name Pentathlon, or "Myclobutanil" under the brand name Immunox. According to Grounds Maintenance online, a fungicidal product called Chipco Signature plus Daconil provided the most potent prevention in their tests. Most systemic (through the roots) treatments last longer than sprays and can't be washed off by rain, making them especially effective for anthracnose prevention.

Prevention
To keep anthracnose at bay after an infestation, you must treat susceptible plants with diligence. This may require adapting your previous gardening practices. Pick up all dead leaves after they fall or are trimmed. Even one diseased leaf can winter-over in the soil or mulch and reinfect the plant in another season. Keep plants dry: anthracnose develops in moisture. An especially humid summer can wreak havoc on an anthracnose-prone plant. Prune the plant so it receives sun throughout and scrub your tools with rubbing alcohol.

Talk to an Arborist
If you prefer, you can always let your local tree service handle the treatment and prevention of Anthracnose. A local tree service, like Trees "R" Us, Inc. on the North Shore of Chicago, should have qualified staff that is not only able to diagnose Anthacnose, but also be licensed to treat it with professional grade fungicides. Here at Trees "R" Us, Inc. we have several certified arborists that are available to service your trees with the utmost care and professionalism. You can trust your trees to Trees "R" Us, Inc.
