Scientists have found a plant that can control weeds naturally. The plant is known as Manchurian walnut tree. This discovery could reduce chemical herbicide use in farming. It promises a safer, eco-friendly solution for crop management.

What Has Been Discovered?

The Manchurian walnut tree produces leaves with weed-suppressing compounds. Leaf extracts release chemicals that inhibit weed germination and growth. Crops nearby remain unharmed, making it safe for farmland. This natural herbicide may outperform some synthetic alternatives.

Who Discovered It and Where?

Researchers at Kyushu University in Japan led the study on the Manchurian walnut tree.
The team was headed by Associate Professor Seiichi Sakamoto and Assistant Professor Poomraphie Nuntawong.

They collaborated with Juntendo University and Chulalongkorn University to carry out field and lab research. The team focused on identifying sustainable, chemical-free farming methods.

What Did Scientists Observe?

Extracted leaves successfully prevented common weeds from growing. Soil treated with the extract showed reduced weed density. Crop plants remained healthy with no negative side effects. The extract also improved soil conditions compared to chemical herbicides.

Further Research on the Manchurian Walnut Tree

Scientists now aim to scale up production of the extract. They plan extensive trials on various soil types and crops. Long-term ecological impact on non-target plants will be assessed. Optimisation could make this a commercially viable, eco-friendly solution.
