摘　　要：结果表明:枯草芽孢杆菌BS-2、解淀粉链芽孢杆菌TB2和枯草芽孢杆菌TL2菌株对荔枝霜疫霉有明显的抑制作用,108cfu.mL-1的TB2和BS-2菌液对荔枝霜疫霉菌丝生长和孢子囊萌发的抑制率最高,分别为63.34%和79.29%;化学农药烯酰吗啉对荔枝霜疫霉的菌丝生长和孢子囊萌发具有较好的抑制效果,其EC50分别为1.70和0.84μg.mL-1.The results were as follows： Bacillus subtilis BS-2, B. amyloliquefaciens TB2 and B. subtilis TL2 could obviously inhibit Peronophthora litchii, TB2 and BS-2 with the concentration of 10^8 cfu · mL^-1 had the best inhibition effect on P. litchii, with the inhibition rates of 63.34% and 79.29% respectively; dimethomorph had good inhibitory effect on mycelial growth and sporangia germination with EC50 of 1.70 and 0.84 ug · mL^-1 respectively.
