Abstract:
Taking 77% copper calcium sulfate，20% bismerthiazol and 1.5% benziothiazolinone as materia,the restrain effect of three fungicides was added into potato dextrose agar (PDA) medium to control the growth of P.c.c. derectly，and colour callalily was induced to resist the soft rot in the field and laboratory were studied.The results showed that P.c.c.was completely inhibited on PDA which contain 1 000 times~125 times of 20% bismerthiazol，and colour callalily could resist the growth of P.c.c. in the laboratory completely，and the inhibition rate was 60% in the field under the concentration of 1 000 times~500 times.The inhibition rate of 77% copper calcium sulfate was about 50%，which was lower than that of 20% bismerthiazol.1.5% benziothiazolinone could not inhibite the P.c.c.in the field and laboratory.The inhibition rate under the concentration of 1 000 times and 500 times of 20% bismerthia zol was not significant differences(P<0.05).
