Watch for mimosa webworm

We have had another relatively mild winter, so watch for defoliation of honeylocust trees from mimosa webworm this summer in southern Michigan. If you are planning on protecting them, watch for patches of foliage that turn brown in late June. Spray when you see the first signs of brown foliage, webbing and caterpillars. Last year, many trees turned completely brown before the webworm was found.
