There are no symptoms before winter after infection, and it does not appear until the wheat turns green in spring. Infected plants produce chlorosis stripes on the new leaves of wheat after 4-6 leaves, and a few heart leaves are twisted and deformed, then the chlorosis stripes increase and spread. The diseased spots grow together into short and irregular stripes with different widths, which are spindle-shaped, and the old diseased leaves gradually turn yellow and die. The diseased plants have few tillers, atrophy, poor root development and obvious dwarfing of severely ill plants.

To prevent and control wheat yellow mosaic disease, 5-8kg of urea can be topdressing per mu during the green turning period, and 75ml of 5% amino oligosaccharide or 200ml of 2% mycotoxin can be sprayed on 50kg of water.

Or spray 0.5-0.75 kg urea +0.2 kg potassium dihydrogen phosphate and 50 kg water per mu, or spray 0.0 1% brassin 3000-5000 times solution, so as to accelerate the transformation of seedling conditions, slow down the development of disease and reduce the damage and loss.

If wheat sheath blight and wheat stripe rust are controlled at the same time, 20 grams of diniconazole 12.5%, 0.5% triadimefon100g and 50-60 kilograms of water can be sprayed per mu.
