I made a stand in 1975 1. Fusarium pathogens census and the investigation of the rate of rice piles; 2. Fungicide control test; 3. Ear morphology, flowering characteristics and wheat leaf pH determination. The test results are summarized as follows: First, the source of census and investigation of carriage rate: Census of the main species of overwintering residues in the field (including the main weeds) carrier bacteria to identify the local sources of pathogen Fusarium graminearum parasites and pathogens. Through the investigation of the rate of rice piles, the time and quantity of pathogens in the current year were clarified
