Help for Barberry bushes - Knowledgebase Question

Question by dalivingston

last year we planted Barberry bushes, the kind that get red. This year they came back beautifullywith a lot of new growth. Now somthing is stripping the leaves from the branchs. It started with the new growth and now has moved to the old. We have ruled out deer, and I put some of the Bayer granules down, I have had sucess with that on other plants, but still the bushes are being stripped. I am going to try slug bait tonight as I have seen slugs around, but not in the area of the bushes. I have also seen Janpanese beetles aroun but not in that area. Any suggestions?

Based on your description, I am not certain what would be eating the barberry foliage. Deer generally leave barberry alone, and slugs would leave behind their tell tale silvery trail. There are very few insect pests of barberry, however there is a weevil that can damage the leaves. I would strongly suggest you consult with your local Penn State county extension for a more specific identification of the pest and based on knowing that, how to control it. If a chemical control is needed they will have the most up to date information on what to use and how/when to apply it for maximum results. It is always better to identify the pest before trying to treat for it.
