April 20, 1981, we Xinzha Brigade in the village of Zhao small home to test the phosphorus phosphoric acid seed dressing concentration, the variety is Guogu 2, the dosage were 0.2%, 0.3%, 0.4%, 0.5% . With no dressing as a control, a total of 5 processing, residential area of ​​0.2 acres. July 21 to investigate the effect of prevention and treatment to the dose of 0.2-0.3% of the seeds of the best effect, prevention of up to 80-86.7%.
