Symptoms: Wheat shuttle mosaic disease is a soil-borne virus disease, and the symptoms are concentrated in late February to mid-March. The chlorotic purple or distorted leaves appear in the newly emerged leaves of wheat after infection. Field surveys showed that the number of farrowings of diseased plants was reduced by 15-18% compared with the number of tillers of healthy plants, and the yield was reduced by about 10%. II. Occurrence: According to field observations in recent years, the time of occurrence of Shuttle Mosaic disease was concentrated from late February to mid-March, and the wheat growth period was at the seedling stage and after returning green. The heavy wheat field crops are heavy and the low-lying land masses are heavy. In the late spring and spring, the spring temperature rises slowly and heavy, and the crops that are not resistant to disease are heavy. III. Prevention: (1) Plant varieties resistant to wheat skein mosaic disease, such as Yangmai No. 2, Ningmai No. 9 and Zhenmai No. 5, etc. (2) Rotation of crops, heavy disease fields can be rotated with barley, rape, broad bean and other crops. (3) Timely sowing, sowing time can be postponed to the beginning of winter before and after November 5-10, to avoid the transmission period of the transmission medium. (4) Add base fertilizer. Enhances the ability of wheat plants to fight against tick mosaic. (5) After the onset of disease, timely nitrogen fertilizer was applied to water to promote the delivery of wheat seedlings and reduce losses.
