Prevention and treatment of Blackfoot Disease starts with seed dressing of Wheat
Wheat total erosion disease, also known as Blackfoot disease, is a devastating disease in wheat production. After the wheat was infected, the tillers decreased, the spike rate decreased, the 1000-grain weight decreased, the light ones reduced the yield by 10% to 20%, the heavy ones reduced the yield by more than 50%, or even no harvest. Wheat can be damaged during the whole growth period, but it is affected by seedling stage and seedling height of 15 cm.

Control of wheat sheath blight by early application of Thiofuroamide in spring
In recent years, the planting area of direct-seeding rice in northern Jiangsu and other places is relatively large, which leads to the late sowing date of wheat. In order to ensure the yield of late sowing wheat, the seeding amount is often greatly increased. The seed amount per mu of high fields is 20~30 kg. The wheat seedlings in the field grow too densely. With the spring temperature rising, the wheat quickly recovers its growth.

Pay attention to the occurrence of diseases and insect pests in wheat seedling stage
In recent years, the symptoms of withered spike often occur in some plots of wheat at milk stage, which has a great influence on the yield and quality of wheat. The main causes of wheat white spike are diseases and insect pests, such as sheath blight, root rot, total erosion, scab, wheat stem fly, wheat stem moth, golden needle worm and so on. Caused by different diseases and pests.

Occurrence and Control Countermeasures of Wheat Yellow Dwarf Disease
Wheat yellow dwarf disease is a viral disease mainly transmitted by aphids, and its damage is quite serious in some years. When the symptom is susceptible to disease at the seedling stage, the leaves lose green and turn yellow, and the plants are seriously dwarfed, and the leaves of seriously diseased plants often cannot survive the winter, or cannot jointing and heading after overwintering. The dwarfing of the late susceptible plants was not obvious, and the upper part.
