Abstract:
Taking four mormal fungicides as materials,inhibition zone method and the grown rate method were used,inhibition effects of different fungicides on competive bacterial edible fungi and mushroom mycelial growth were studied,to screening out high efficiency and low toxicity fungicides on competitive fungi.The results showed that fungicides had different inhibition rates on spore sprouting and mycelial growth of Trichoderma sp.and Penicillium sp.，the inhibition zone diameter were 5.30-5.66 cm when car bendzim (Lanfeng) concentration was 400-1 200 times，and there were not significant difference between concentration gradients，the mycelial inhibition rates increased with the concentration，the mycelial inhibition rate was 13.4%when the concentration was 400 times；the inhibition zone diameter of Thiophanate-methyl was 4.22 cm，the mycelial inhibition rate was 16.8%when the concentration was 400 times；the inhibition zone diameter of Sandofan was 4.10 cm，the mycelial inhibition rate was 17.6%when the concentration was 400 times.The spores were the most sensitive to Carbendazim （Lanfeng)，the inhibition zone diameters were 5.44-5.86 cm，and there were not significant difference among concentration gradients，the mycelial inhibition rate was 57.54%when the concentration was 400 times.The inhibition zone diameter of Thiophanate-methyl was 3.78 cm，the mycelial inhibition rate was 100%when the concentration was 400 times；the inhibition zone diameter of Sandofan was 3.20 cm，the mycelial inhibition rate was 51.10%when the concentration was 400 times.Carbendazim 2 had not showed the inhibition effect on spore sprouting and mycelial growth of Trichoderma sp.and Penicillium sp..The inhibition effect was different with different concentration of fungicides on different mushroom mycelial growth；appropriate fungicides should be chosen by different mushroom and pathogenic fungi.
