Corn stem rot

On September 18, the corn varieties participating in the national Huanghuaihai Xia Corn District Test in the Test Base of the Baofeng County Agricultural Sciences Institute in Henan Province were growing up.

On September 18, Dr. Zhou Haifeng, an expert on the prevention and treatment of plant diseases and pests at Henan Agricultural University, recorded diagnosis and treatment of corn germinated stem rotation strains at the test base of the Baofeng County Agricultural Sciences Institute.

The corn varieties participating in the national Huanghuaihai summer corn area are growing up.

The Agricultural Sciences Institute of Baofeng County, Henan Province, shoulder the task of the National Huanghuai Haixia Corn District, and Henan Agricultural University was entrusted to the national Huanghuaihai Xia corn group Baofeng pilot field stem rot monitoring and appraisal. On the same day, with the cooperation of the breeding experts of the Agricultural Sciences Institute of Baofeng County, the 67 varieties were appraised for the corn of corn in the 201 communities. It is understood that the monitoring point of the country's Huanghuai Summer corn group's field stem rot is set up in a total of two in the country, namely Henan Baofeng and Shaanxi Liyang. Since 2010, the Baofeng County Agricultural Sciences Institute has undertaken the monitoring of corn stem rot for 12 consecutive years.

Corn is the main economic crop in my country, and it is planted in north and south. Corn has the characteristics of strong adaptation and high yield, but in recent years, the frequent diseases and insect pests of corn have a great impact on the yield of corn. Therefore, prevention and treatment of diseased and insect pests have become the top priority of corn planting. Essence After the onset of corn plants, corn seeds will not be fully fulfilled, weight loss or incomplete maturity, and at the same time, it will also lead to damage to corn plant stems and indirectly cause the phenomenon of plant seedlings during the seedlings. Not only did the corn production reduce the yield of the year, it also had an impact on the production of planting in the next year. It is an important disease problem that needs to be solved on the corn. Stem rot is one of the severe diseases in the late period of corn. The national seed management department rejected one vote for important diseases such as high -sensitive stem rot in the review session. Wang Shuangzheng
