It is necessary to prevent total erosion disease after planting wheat turns green.

Wheat total erosion disease, also known as Blackfoot disease, is a typical root disease, which can occur in the whole growth period of wheat. The pathogen only infects the root and the base of the stem. The occurrence and severity of the disease is affected by many factors. The disease of continuous cropping is serious; wheat and summer corn are cropped twice a year for many years, the disease is serious; soil fertility is low, the proportion of nitrogen, phosphorus and potassium is out of balance, especially in the area of phosphorus deficiency; it is rainy in spring and high soil moisture is conducive to the disease.

Soil treatment wheat total erosion disease occurred in the mu with 50% carbendazim and 15% strychnine wettable powder 1 kg each, mixed well with 30 kg fine soil, scattered on the surface, and then ploughed and sown.

Seed dressing can be done with 3% verapamil 50 ml + 2.5% happy hour 10 ml, add water 150 ml and mix well, mix seed 10 kg. You can also use 12.5% total erosion water suspension agent 20: 40 ml per mu, mix 10 kg of wheat seeds with 150 grams of water, and dry and sow seeds for 3 hours after seed dressing.

Chemical root irrigation for diseased fields without chemical soil treatment and seed dressing in wheat three-leaf stage, green stage and jointing stage, 20% strychnine 200g / mu was mixed with water 100kg / mu, and sprayer (remove sprinkler) was used to spray the solution along wheat ridge to make the solution infiltrate into the root through wheat seedlings, which can greatly reduce the harm of wheat total erosion disease.
