Various winter weeds are usually present in no-till fields in sufficient numbers in early spring to warrant a burndown herbicide treatment before planting a summer row crop. Proper identification of these weeds is critical for selecting herbicides and determining appropriate rates of application. This publication is intended to serve as a practical reference for the identification of weeds present in no-till production systems. It includes more than 130 color photos of 45 common weeds. A four-page taxonomic key assists in identification by means of distinctive plant features. Also included are a glossary and a guide to herbicides for controlling early-spring weeds in no-till fields.

Common mulleinCommon mullein is a biennial plant, producing a large rosette during its first year of growth. The leaves are densely hairy, giving it a fuzzy texture. The dense hair gives the plant a grayish appearance. Flowers produced during its second year of growth are bright yellow and occur on long terminal spikes.
