A rubber resource with a Russian connection




Klamath Falls Herald and News

    What was once a government project in the Klamath Basin could further tie area agriculture to industry. 

    Daryl Ehrensing, senior faculty research assistant at Oregon State University, is researching Taraxacum kok-saghyz, or Russian dandelion, a plant used by Russia and the United States to produce rubber in the first half of the 20th century. 

    That same plant could bring Klamath Basin farmers into the world rubber market. 

    “Anywhere dandelions will grow, these will grow,” Ehrensing said. 

    Today’s rubber industry produces 60 percent of the world’s rubber synthetically from petroleum products. The other 40 percent is natural. Synthetic rubber is inferior to natural rubber and can only be used when blended with natural rubber. 

    Currently, all natural rubber is harvested from rubber trees in Malaysia and South America. Such an arrangement allows the nations in control of those areas to monopolize the rubber market, Ehrensing said. 

    Before World War II, Joseph Stalin wanted to decrease the USSR’s dependence on foreign rubber supplies. He ordered his researchers to find a natural alternative that could be grown in Russia. The result was koksaghyz, which is native to Kazakhastan. 

    The United States began experimenting with the plant during World War II, after the Japanese conquered Malaysia and froze the rubber supply. It was grown in several areas, including the Klamath Basin, and was reported to have fared well. 

    A series of events made the world forget about kok-saghyz. The Russians lost their stock of varieties after becoming a democratic republic, and didn’t maintain storage units. 

    The British requested the U.S. government destroy their supply of the plant after World War II to preserve the British interest in Malaysia. 

    “Basically, everyone forgot about this thing,” Ehrensing said. 

    Cooper Tires, Titan Industries and Goodyear have expressed interest in the new rubber source, he said. No special machinery would be needed for harvest. The rubber has been considered equal to or better than the rubber tree product. 

    The biggest benefit would be that farmers could begin harvesting a year after planting instead of waiting seven years needed for a rubber tree to mature, Ehrensing said.
