Plantwatch: Russian dandelion offers solution to global rubber shortage

Scientists are revisiting the use of the Russian dandelion, Taraxacum koksaghyz, as a sustainable alternative to traditional rubber sources amidst a global natural rubber shortage. During World War II, Allied forces utilized latex from this dandelion, discovered by Soviet scientists in Kazakhstan, to meet rubber demands when supplies from the rubber tree, Hevea brasiliensis, were disrupted. Following the war, the industry reverted to rubber trees, but current challenges are prompting a renewed interest in the dandelion. The increasing global demand for rubber, coupled with the vulnerability of rubber trees to a prevalent fungal disease and the impacts of climate change-induced extreme weather, has created a critical need for alternative sources. The Russian dandelion offers several advantages, including its ability to thrive in temperate climates, its status as a sustainable crop requiring minimal pesticides and water, and its potential to mitigate the deforestation associated with tropical rubber tree plantations. This resurgence in interest highlights a potential solution to a pressing global resource scarcity.
