Abstract and summary

Effective chemical control of alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.) has been prevented by rapid regeneration of plants from inactive axillary buds following treatment with herbicides. Destruction of phloem, cambium, and associated parenchyma occurred above and within the nodes of plants treated with 2 lb/A dichlobenil (2,6-dichlorobenzonitrile) or dicamba (2-methoxy-3,6-dichlorobenzoic acid). Application of dichlobenil and dicamba in combination increased the extent of tissue destruction. Herbicidal activity was noted within the axillary buds only when vascular strands between bud and stem were well differentiated.
