The weed enclosed in this folder is known as Halogeton. It is very
poisonous to sheep and may oause heavy losses principally during the late fall
and early winter* This plant is equally toxic to cattle, but has caused little
loss am<m£ this olass of livestock because of its unpalatable nature#
During the past few years this plant has spread over many desert fanges in
Idaho, Uevada, Utah and Wyoming and is dangerously abundant, at the present time,
on some of the fall and winter ranges.
During the jnonth of November about 1100 sheep were poisoned by Halogeton on
the Raft River ranges in Cassia county. These losses are very serious and offer
a great threat to the sheep industry.
Halogeton is an annual, herbaceous plant growing to a height of about one
foot, on the average. It is a very prolific produoer of seed and because of
this large seed production and the ease of their dissemination, the task of con-
trolling its spread and finally eliminating the plant*in any area appears to be
a hopeless one.
It, therefore* appears that it will be necessary to devise methods and
systems whereby we oan live with this plant. Perhaps by utilizing infested areas
during portions of the season when the plant is less toxic or by rehabilitation”*
through reseeding, we oan gain use of these ranges.
Its general, appearance resembles Hussian Thistle, however, its leaves are
not sharp and thorn-like as are Russian Thistles, but are soft and rouand pointed
with a hair-like stipule at the apex of each leaf.
The toxic agent in Halogeton is an oxalate which is present in the stems
and leaves in large quantities. Studifs have indicated that the greatest danger
of poisoning from this plant occurs during the fall and early winter. This may
be due to an increase in palatability after the plant has been killed by frost.
As far as is known no practical remedial treatment has yet been developed.
Halogeton is native to, Iran and other areas bordering the Caspian Sea.
It made its first appearance in this country about ten years ago when a botanist
observed it near Wells, Nevada.
The Grazing Service and several, state experimental stations are continuing
studies of Halogeton in an attempt to find methods of combating this menace#
