Lysenkoism gained traction in other communist countries, including China and East Germany. It was often seen as aligned with socialist ideology and offered a supposedly rapid solution to agricultural problems.

Lysenkoist methods were widely implemented during China's Great Leap Forward, leading to disastrous agricultural consequences and contributing to widespread famine. The 'Four Pests Campaign' is a notable example of pseudoscientific policies informed by Lysenkoism.

Lysenkoism influenced agricultural practices and research in East Germany for a time, albeit to a lesser extent than in the Soviet Union or China. The focus was on collectivized agriculture, which was a better fit with the pseudo-science.

As the scientific flaws of Lysenkoism became undeniable, it was gradually rejected in most countries, including those that had previously embraced it. The recognition of the importance of Mendelian genetics grew globally.
