Posted on August 13, 2019 by admin

Ash trees are one of the most common species of landscaping tree here in Indiana, namely white Ash and American Ash. Admired for their unique bark patterns, balanced canopies, and stunning foliage progressions, Ash trees make for a wonderful addition to any property. Unfortunately, just like any living organism, Ash trees are susceptible to all sorts of diseases and health complications. If you are experiencing some concerning changes or behaviors with the Ash trees on your property, it is important to take action fast, before the root of the problem can worsen or spread to other trees in your landscaping.

Continue reading to learn some common problems associated with Ash trees, as well as, what you can do if your trees are suffering a similar decline.

Ash Tree Diseases

The most common diseases that affect Ash trees are Ash yellows, Verticillium Wilt, ash rust, and Ash Anthracnose. Ash yellows is a slow-killing tree disease caused by a microorganism called Candidatus fraxinii that harms a tree’s vascular system. This disease tends to mostly affect white ash and green ash species. Although there is no cure for Ash yellows, pruning and fungicide treatments in its early stages is an effective way to manage Ash yellows. Verticillium Wilt, ash rust, and Ash Anthracnose are fungal diseases that result in leaf wilting, canopy dieback, and more. These diseases are generally treated with pruning and fertilizing.

Ash Tree Pests

By far the most common pest problem for Ash trees are Emerald Ash Borers (EAB). Emerald Ash Borers are small metallic green beetles that target Ash trees exclusively. Larvae look like small maggots or white worms, while adult beetles are about the size of a raisin, and have metallic green backs. Adults lay eggs inside the bark, and when their larvae is born, they eat their way to the surface until full-grown. Once adults, they emerge from the bark, leaving behind D-shaped exit holes in the wood. Additional pests that attack and infest Ash trees include oystershell scales, ash plant bugs, and aphids.

In order to prevent pest infestations, arborists commonly apply systematic insecticides for optimal tree protection. Systematic insecticides contain the active ingredients dinotefuran, emamectin benzoate, or imidacloprid. These chemicals have all been registered with the Environmental Protection Agency and deemed appropriate for agricultural applications.

Posted on February 28, 2015 by admin

Emerald Ash Borers are beetles that can cause a significant amount of destruction to Ash Trees. In order to prevent such infestations, arborists commonly apply systematic insecticides for optimal tree protection. Systematic insecticides contain the active ingredients dinotefuran, emamectin benzoate, or imidacloprid. These chemicals have all been registered with the Environmental Protection Agency and deemed appropriate for agricultural applications. They are approved to be used for certain gardens, crops, and foods because they are “reduced-risk” insecticides. They are also used in certain veterinarian applications, like deworming medication for horses and dogs. Continue reading to learn about each insecticide ingredient and where they are applied for pest control purposes.

Active Ingredients

The ingredient imidacloprid has low enough toxicity levels that it can be used on pets to prevent fleas and ticks. It is used to prevent insect infestations and other types of pest infestations in turf grass, farming crops, and landscaping florae.

The ingredient, dinotefuran, is actually sort of new in the world of insecticides. It shares similar properties as the last ingredient, but more information about this is not yet conclusive because there’s not enough research about it quite yet.

The last ingredient, emamectin benzoate, actually comes from a natural source. It is taken from soil bacterium and has been registered for use with the Environmental Protection Agency for more than 10 years. It is approved to be used as a foliage spray for vegetable crops and also cotton fields. Another interesting fact about emamectin benzoate is that it is also used in salmon aquaculture to prevent parasitic lice infestations.

Identifying Common Tree Diseases

Posted on July 3, 2014 by admin

When it comes to landscaping trees, most diseases are simply aesthetic and can be treated without problem. However, there are several other types of tree illnesses and threats that can both harm and kill trees. It is best to treat an unhealthy tree as soon as you are aware there is a problem. Perhaps your tree leaves are turning brown and curling at the ends, or the bark is starting to peel off. If you are noticing a decline in your tree’s health, it is time to consider professional tree care and assistance. Catching a tree disease early on can save the lives of your landscaped trees, as well as, all other flora on and around your property. Continue reading to learn more about common tree diseases, and how to identify them in their early stages.

Emerald Ash Borer

The Emerald Ash Borer is a tree beetle that attacks Ash Trees and never hangs out alone. They come in large colonies that can quickly infest trees and deprive them of food and nutrients. These are moderate-sized green beetles with shiny backs and exoskeletons. They are known to make S-shaped larval galleries in the outer bark of trees, and D-shaped emergence holes to exit them. These carvings are tale-tell signs of an EAB attack. These beetles can quickly harm or kill a tree. Signs of an EAB infestation include crown dieback, or when the canopy of trees begin to die and expose dead tree branches. Other signs include bark splitting, epicormic sprouting, and woodpecker feedings. Woodpeckers love to eat Emerald Ash Borers, so if you see a crowd of them on a tree, you can assume it is infested. Epicormic sprouting is when a tree becomes desperate to grow new branches, and begins new growth towards the bottom of the trunk. To get rid of these beetles, a professional Fishers Indiana Tree Care specialist is required.

Oak Wilt

Oak wilt commonly affects, you guessed it, Oak Trees. This diseases is commonly found in White Oaks, Red Oaks, and live oak trees. It is commonly found in Eastern parts of the United States, and is one of the most serious tree diseases around. Forests and landscapes are losing thousands of Oak Trees each year to Oak Wilt disease. It is a fungus that infiltrates wounded or weakened trees. The seriousness with this disease has to do with the fact that the fungus can move from tree to tree, through the root system or through insects. Unfortunately, once an Oak tree is infected with this particular fungus, there is no cure.

Chestnut Blight

This is another tree fungus disease that affects Eastern regions of the United States. It prefers hardwoods, like the American Chestnut Tree. In the past, professionals have tried to cut and remove the roots of infected trees to stop the spread of the fungus; however, it wouldn’t go away. Although it seems there is no cure for this disease, it seems to act as a nonfatal parasite to some species; such as Chinquapin trees, Spanish Chestnut trees, and Oak trees. WE only hope this fungus can one day be controlled and treatable.
