Chlorosis

Chlorophyll is the molecule that a tree utilizes to make energy for itself. Trees with this condition are making less energy. This condition can cause a weaker, less durable tree. A healthy root system requires food made in the leaves to function and grow. Healthy leaves require healthy roots to extract nutrients from the soil. Without one, the other languishes. Call Walker Tree Service – we can come out and give you a quote to help restore your tree.
Diagnosis & Symptoms:

Since chlorophyll is what causes the tree to be green, chlorotic trees will often show symptoms where the color of the tree is light green, yellow, reddish, and in severe cases white.

Manganese (Mn) and Iron (Fe) are often difficult to distinguish from each other without foliar chemical analysis. Some researchers suggest the fine veins will become chlorotic with Mn deficiency while they remain green on Fe deficient trees. In practice, this is difficult to determine in the field, so most Mn and Fe deficiencies are diagnosed by commonly affected species.

 - Maples more frequently have Mn deficiency

 - Birch and oak more frequently have Fe deficiency

PREVENTION

Walker tree service has three different plant protection products to treat your ash trees to protect them from EAB. Because each of these products is used at different times of the year, Walker tree service can create a schedule for maximized effectiveness. If a tree is properly protected and receives treatment early, the success of sustainability is high. The idea is to protect the tree early before damage does occur.
MANAGEMENT AND CONTROL-

The condition can be effectively managed if you currently have EAB damage, in most cases. EAB was recently discovered in our area. The experts have speculated that EAB has been in our area for 5 to 6 years. Control is crucial to prevent the spread of EAB.

Trees at Risk

All native ash trees, including green, white, black, blue, and pumpkin ash.

Signs of Damage:
Symptoms of an early infestation can be hard to diagnose. Be on the lookout for multiple declining ashes in a given area and D-shaped exit holes that are approximately 1/8" in diameter. As an infestation progresses, small vertical splits in the bark can be seen on twigs or the main trunk and woodpecker holes may be present on trees. Trees may die in 2-4 years or less.
Physical Appearance:
  • Typically the top 1/3 of the crown shows dieback and thins. Trees appear to lose about 30% to 50% of their canopy after 2 years of infestation 
  • As the tree declines, epicormic shoots form at the interface between healthy and dead tissue anywhere in the canopy
  • Distinct "S" shaped, frass-filled, larval galleries that can range from 4-20" in length etch the xylem and phloem
  • Adults are slender and can be 1/4" to 1/2" in length, they are dark metallic emerald green
  • Larvae range in size 1-1 1/4" in length with pincer- like appendages on the last segment

Insect Control

Trees may show symptoms from insects and diseases during the late summer and fall. Many common invasive pests can be treated in the fall to prevent attacks the following year. Why not give us a call and get a head start on protecting your trees for the next year.
