Cruciferous vegetable black soot fungus (Alternaria brassicicola) cultured for one week on A slant medium
The spore concentration was adjusted to about 60 to 801 tAj (xiso) using a microscope, and the seedlings were inoculated with :'R-. After the interview,
Cultivate for 6F1 in a greenhouse (30'C) and count the lesions.
The average number of lesions per leaf was calculated and the control value was calculated in three tables.
