Pest Alert
Be on the lookout for the invasive Emerald Ash Borer.
Since its arrival in the US in 2002, it has been on the move and has killed millions of ash trees in our northern states; and may be moving our way to Florida. The adult pest, which is metallic green on top and silver beneath and with large bulging eyes, lays eggs in the trunk of an ash tree. The eggs produce larvae that tunnel just below the tree bark creating galleries that interrupt the nutritional processes of the tree. This is a very serious pest, and can hitchhike on fire wood brought in by campers from up north. For additional information, go to http://www.freshfromflorida.com/pi.

Thank you for your inquiry.
I don’t believe that your avocado problem is caused by the Emerald Ash Borer. I think that you may have a problem called Laurel Wilt Disease which affects avocados. This is a fungus disease that is spread by the Red Bay Ambrosia Beetle. What it does is restricts the flow of water within the plant. I suggest you check out the website included in my previous blog for the Emerald Ash Borer which was http://www.freshfromflorida.com/pi. Then from this website click on Laurel Wilt Disease. There you will find several articles related to this problem. If you think you have this disease, or are not sure, contact your local County Extension Office and ask them to verify your problem.
Good Luck and thanks again for checking out my blog. If you have any further questions on plants, please do not hesitate to respond.
