Considering this problem, during the years 2002 through 2004, we studied the occurrence regularity and controlling technique for the disease in the middle of Shaanxi province, and took some experiments for medicament effectiveness. The results show that different medicament can bring out controlling effectiveness against the disease beyond 80%, and the controlling effectiveness can approach to 90.12% using 40%Scala SC1000.
