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 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.
