Buckeye Tree: Diseases and Pests

A buckeye tree is a beautiful addition to any garden or backyard area, but like other trees there are specific buckeye diseases and pests that can harm it. A buckeye is also susceptible to the pests and diseases found in the horse chestnut. This article will help you identify possible buckeye diseases, pests and treatments if known and available.

Buckeye Tree Pests

Japanese Beetle: Many of you know these pests by their shiny green exoskeleton and spiked legs. They resemble the horsefly at a quick glance, but they love to devour the buckeye. They attack the leaves and eat them down to the vein. The leaves located on the top of the buckeye and those on the south side are the ones attacked the most. The Japanese beetle attacks suddenly without warning and can be devastating to the buckeye. There are commercial traps available on the market and you can hand pick them and toss them in soapy water. There are chemical treatments both toxic and all natural.

White-Marked Tussock Moth: This moth is easily identified by its yellow body and red head. They are also fuzzy like many other caterpillars. There are black markings on four tufts hair on their back. There is no chemical control at this time for them.

Buckeye Diseases

Leaf Blotch: Unlike other tree diseases, this is easily spotted. You will begin to notice discoloration in the leaves of the buckeye. The size of the blotches varies and change over time. The infected areas will be off-color and water-soaked but will turn a light reddish brown with a yellow outline. Once the entire leaf is infected it will turn brown, dry out and fall off. This disease can spread to the leaf stalks. There is no chemical control with the only solution is time and to remove infected leaves from the area.

Leaf Spot Disease: This is similar to leaf blotch in that it infects the leaves but the appearance differs. The infection is visible as small brown circular spots. There is no chemical available for the treatment but one can try removing the infected leaves before it spreads.

Powdery Mildew: In order to find this particular disease you need to do a little investigating. Look under some of the leaves of the buckeye and if you see a white mold then you have powdery mildew. You can purchase a spray fungicide in order to get this disease under control.

Anthracnose: Look around the shoots of the buckeye a few inches from the tips. If the buckeye has this disease the area will appear shrunken. The outer layers of the area may also be ruptured. There is a fungicide on the market to rid the disease but you can also try pruning the infected areas to get it under control.

Leaf Scorch: This is a problem with physiology. The margins of the leaf begin to turn brown then over time the browning moves inward between the veins. The entire leaf will eventually turn brown. Keeping the plant well watered when it's dry helps prevent this disease.
