Abstract
Methods for treating plants and fields in agricultural applications are provided by selective delivery of superheated steam. Particularly preferred applications include delivery adjacent to grape vine leaves in order to defoliate basal leaves and to kill localized insect pests, and by injecting superheated steam in strawberry beds prior to planting to kill nematodes. The superheated steam is delivered at temperatures in excess of about 250.degree. F.
