SALSOLA KALI 
RUSSIAN: THISPLE 
USSIAN THISTLE (Salsola Kali).—Russian cactus and R. Tumbleweed 
are other names for this annual weed that has, since its introduction into 
America in perhaps the ’90s, spread over the Canadian Prairie provinces and 
much of the central plains states west of the Mississippi river. It grows bet- 
| ter than most crop plants in dry soil. Good growing conditions favor crop 
| plants which then crowd the Russian Thistle. Return of dry seasons encour- 
ages the weed. The plant is unique in that it can grow in somewhat alkali 
soil and thrive in soils too dry for crop plants. There is a vast difference in 
the appearance of the plants up to the time of blooming and when they are 
mature. The early leaves are long, slender and succulent while the later 
leaves are short, sharp tipped and hard. When mature, the stem becomes 
brittle and breaks off near the surface of the soil. Then because of the ball 
shape of the plant, it is readily blown about by the winds spreading its seeds 
as it rolls. Its seeds are spread far and wide in alfalfa, sweet clover and red 
clover seed. During dry years it has furnished feed for livestock that other- 
wise would have starved if not shipped away. Clean crop seed is the first 
requirement in control, followed by improvement of the soil by fertilizing and 
increasing its water holding capacity. Cut off the young plants, handle 
stubble fields to prevent ripening of seeds. Plow late in the spring and sow 
to emergency hay such as millet, or sudan grass.
