Problems solved by technology

Fusarium head blight is caused by the fungus of the genus Fusarium. While causing losses to the yield of wheat, it also produces mycotoxins mainly deoxynivalenol (ie, vomitoxin DON), which is harmful to humans and animals. , eating sick wheat can cause acute poisoning symptoms such as dizziness, fever, nausea, and diarrhea. In severe cases, it can cause bleeding, affect immunity and fertility, etc., and directly pose a threat to human and animal health and life safety. Studies have also shown that DON has carcinogenicity. possibility of
