Emerald Ash Borer

    • What to look for EAB Emerald Ash Borer Treatment Process
    Emerald Ash Borer (EAB) is an exotic insect native to Asia that has been quickly spreading across the United States. It was found in Brown country in July of 2009 and more recently Outagamie county in February of 2015. Other confirmed finds have been in Door, Winnebago, and Calumet counties. To prevent your ash trees from being infested we recommend treating with a systemic insecticide. The insecticide would be injected directly into the trunk. We do offer an organic EAB treatment as well.

Oak Wilt

    • Oak Wilt
    Oak wilt is caused by a fungus that invades the vascular system of the tree where water moves. With the presence of the fungus, balloon like bumps called tyloses form and plug up the waters path through the tree. Once this water movement is slowed the leaves wilt and fall off the tree. Oak wilt is distributed through the following counties we service: Brown, Outagamie, Shawano, and Oconto. Oaks in the red oak group like northern red, northern pin are more likely to get oak wilt than the oaks in the white oak group. One way to prevent oak wilt spread is by pruning them in the dormant season. We do offer injection treatments that offer great protection. Injections have better results if used as a preventative instead of a curative.

Dutch Elm Disease

    • dutch elm disease
    Dutch elm disease (DED) is a fungal disease that elms like American, rock, and slippery are more prone to getting. The fungus invades the water-conducting vessels causing them to clog, this stops all movement internally, causing the trees to wilt and die. Dutch elm disease is spread through elm bark beetles or by root graft. Early detection is key to protecting your elm tree(s). Flagging which is yellowing leaves on outer branches mid to late summer is an easy symptom to spot. Trunk injection of a fungicide can be done to protect your elm from getting Dutch elm disease. Pruning out infected limbs and deadwood is also recommended during the dormant season.

Bronze Birch Borer

    • bronze birch borer
    Bronze birch borer is a native flat headed borer that attacks trees under stress. You will start to see die back in the upper canopy as the bronze birch borer starts towards the tips and works its way down the tree. When infestation of the bronze birch borer is first noticed an injection of an insecticide is recommended. The next step would be to improve the trees overall health. This can be done through our organic root program.

Apple Scab

    Apple scab is a fungal leaf disease that affects the Malus spp. Symptoms usually show late summer. Leaves have brown to black spots and usually turn yellow and fall off. Treatment is recommend if the tree is defoliated year after year in late summer. Injection is scheduled after the tree is done flowering and is in full leaf. You should see some improvement the first year but some leaf drop may still occur. We recommend treating two years in a row then treating every two years after that.

Yellow Leaves (chlorosis)

    • image of a tree with Iron Chlorosis
    Come late summer you may find that your leaves are no longer green. This change in color to yellow can be an indication of nutrient problems. This yellowing of leaf tissue is known as chlorosis. Lack of iron is the most common nutrient problem but yellowing can also be caused by nitrogen, zinc, or manganese deficiencies. There can be other reasons why the leaves are turning yellow like high soil pH, compacted soil, damaged roots, or poor drainage to name a few. To help with yellowing leaves an injection can be done. Before injection is the chosen route we recommend looking into improving the soil inside the drip line. This is done through our R00T program.

Growth Inhibitor

    • growth inhib
    Growth inhibitor (paclobutrazol) is a treatment that is used to control growth in the crown. The tree or shrub being treated grows more slowly which requires less pruning. One treatment gives you up to three years of reduced growth. Another benefit of a growth inhibitor is that when growth is reduced above ground, below ground continues to grow. With more roots to shoots, you have a healthier tree. Paclobutrazol can also reduce chlorosis, prevent drought stress and aid trees affected by construction damage.

Gypsy Moth Control

  • Winter egg mass spray: Spot treatment of gypsy moth egg masses with a spray oil that penetrates the protective layer over the eggs. This prevents the eggs from hatching. We do our best to cover every visible egg mass but some may still hatch. We recommend following up with an insecticide treatment.

  • Spring trunk injection: Trunk injection of an insecticide to reduce the population of feeding caterpillars. When treated the insecticide flows through the trees vascular system to the leaves. When the gypsy moth caterpillars feed on the leaves they ingest the insecticide.

Japanese Beetle

    • Japanese Beetle
    Japanese beetles weren't found in the United States until around 1916. In our area there seems to be pockets of infestation. Grubs feed in the soil on grass roots while the adults feed on more than 300 different plant species. One of their favorite tree species to feed on is the American basswood also known as a linden tree. Often times feeding can be so heavy that the top of the tree can turn brown as the leaves die. With an injection of an insecticide we can reduce the amount of feeding and damage to the tree.
