The long-term goal of Interveinal Chlorosis treatment is to establish a healthy root system. This process may take several years. The most effective treatments involve a multi-faceted approach. The first step is to apply a form of highly available iron directly to the vascular system to supply the tree with what it needs to immediately manufacture chlorophyll and regain its ability to produce energy. Another step of the process is to enhance the ability of the tree to effectively produce fibrous roots.
Using Verdur ™ to Stimulate Chlorophyll Production
Verdur provides a form of iron that is immediately available to the tree. The purpose of treatment is to evenly and completely cover the entire crown of the tree with enough active ingredient. This is best done through a process called macro-infusion. This is a process of drilling small holes into the root flares of the tree and inserting small tees attached to a harness that is connected to a reservoir. The average tree will absorb up to a few gallons of material. The best time to treat trees that have variable chlorosis is in the fall so that even distribution can be achieved. Trees with consistent chlorosis throughout the canopy can be treated earlier in the season. Old treatment processes used highly concentrated materials, which could damage the tissue around the injection site and gave incomplete distribution. Results last approximately 3 years from one Verdur treatment.
Using Cambistat ® to Stimulate the Root System
Cambistat has been shown in university studies to increase the size and surface area of root systems. It slows the expansion of cells in the top part of the plant which allows energy to be redirected to other parts of the plant. It also increases a hormone that stimulates root growth. This combination of events increases the plants health and vitality.
 Other Cultural Practices
Certain species of trees such as river birch and silver maples have evolved in river bottoms or soils rich in organic matter. These trees have a difficult time maintaining a healthy root system in urban areas that have poor soil conditions. It is recommended that a mulch ring be placed around the tree. Mulch provides a more favorable growing environment for roots.
