Put on the nano "raincoat" for wheat, and researchers have developed a new technology for prevention and control of wheat ear germination.

November 05, 2018

On September 6, the reporter learned from the Hefei Institute of Material Science of the Chinese Academy of Sciences that the research team of the Institute of Technical Biology, Wu Lifang, recently made new progress in the research of wheat ear germination prevention and control technology. The researchers used modified natural nanomaterials as the main raw material. A wheat germination protection agent is prepared, which can replace chemical pesticides to prevent and control ear germination. This result is of great significance for improving wheat quality and reducing the environmental release of chemical pesticides.

As a global agricultural problem, wheat ear germination not only affects the yield, but also seriously reduces the processing quality and seed value of wheat, resulting in serious economic losses. Breeding germination resistant varieties, suitable sowing and harvesting, and chemical control are common practices for controlling ear germination. Although chemical control can inhibit ear germination to a certain extent, it has the disadvantages of high cost, poor stability, easy blindness caused by pollution and prevention. As people's demand for good life and food quality grows, low-cost, non-toxic, and efficient techniques for inhibiting ear germination have great market demand.

The research group prepared a hydrophobic nano-material by modifying the attapulgite of natural nano-materials. The material can form a dense hydrophobic structure on the surface of wheat grains, which significantly inhibits the respiration and absorption of water by wheat seeds. The technology has the advantages of simple application and environmental friendliness, and has a good application prospect. Relevant results have been accepted and published by the American Chemical Society's core journals in the field of green chemistry.
