Management
Guidelines:
Type and Class of
Livestock:
All classes of sheep and goats; Sericea can be
toxic to cattle.
Grazing Objective:
Reduce plant biomass and prevent flowering and
seed production.
Growth Stage for
Treatment:
It is important to graze young plants early in
the season. Sericea becomes much less palatable
after bloom as levels of lignin and tannins
increase with maturity. Two or more treatments
are necessary each season and three to several
years are needed to weaken plants.
Potential Effectiveness:
Grazed plants are often smaller next year, but
plant density has not been shown to decrease
with grazing. Early intensive grazing followed
by chemical control seems to provide the most
effective control of Sericea.
