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 in the whole growth period, but the damage is the most serious in seedling stage and seedling height of 15 cm. The occurrence and severity of the disease is affected by a variety of factors, continuous cropping is serious; soil sand ventilation is good, alkaline disease is serious; soil fertilizer deficiency is serious; it is rainy in spring and high soil moisture is conducive to the disease. Once the wheat is sick, then spray control, the effect is very poor. The best way to control wheat blackfoot is to use chemicals to mix seeds before sowing, which is economical, effective and easy to operate. According to the production test, 12.5% total erosion net 20 ml per mu is selected, the amount of seriously diseased field can be increased to 30 ml, 500 ml 700 ml for water, and 10 kg of wheat seed can be mixed evenly. 4.8% suitable wheat Dan 15 ml 20 ml for water 500 ml, mixed wheat seed 10 kg, stir evenly, pile up for 6 hours and 12 hours, and sow seeds after drying. Seed dressing with the above chemicals can play a good preventive effect, and the probability of wheat infected with Blackfoot is significantly reduced.
