为了寻找保护性杀菌剂和内吸性杀菌剂复配比例及其对黄瓜蔓枯病的防治效果，

In order to find protective fungicides and fungicide compound and its proportion Fangzhixiaoguo gummy stem blight of cucumber, select herein azoxystrobin, carbendazim, hymexazol, fludioxonil • A fine, Fu-fu • zinc and manganese-zinc-dioxanone • 6 kinds of fungicides, bactericides virulence determination of six spherical shell of black rot fungus (Didynnella bryoniae) hyphae, and measuring a synergistic pharmaceutical compound which cucumber gummy stem blight Fangzhixiaoguo disease. The results show that azoxystrobin measured growth rate method, carbendazim, hymexazol, fludioxonil • A fine, Fu-fu • • zinc and manganese-zinc-dioxanone Fungicides in a spherical shell of black rot fungus (Didynnella bryoniae ) mycelial basis, fungicides to virulent compounding ratio further screened, and synergism was determined Fangzhixiaoguo pharmaceutical compound gummy stem blight of cucumber. The results showed that: Fu-fu • • zinc and manganese-zinc-dioxanone EC50 cucumber gummy stem blight of melons were mycelial 16.166 μg • mL-1 and 58.740 μg • mL-1. Fu-fu • • both zinc and manganese-zinc-copper evil complex ratio of 1: 3 and 1: 2, the value of efficiency (SR) 2 653.57 and 399.58, respectively, significantly higher than the other ratios synergism, and both ratio Fangzhixiaoguo compound on gummy stem blight of cucumber was 85.72% and 78.57%, respectively. It can be said Teoh • • Four zinc and manganese-zinc-copper complex evil can be improved Fangzhixiaoguo gummy stem blight of cucumber.

In order to find the ratio of protective fungicides and internal absorption fungicides and their prevention and treatment effect on cucumber cranberry disease, this paper selects 6 kinds of fungicides, such as sepsis ester, polymyabacteria, mycobacteria, fine mecosin, Fu Fu zinc and ketone-manganese zinc, and determines 6 kinds of fungicides to the black-corrupted bacillus (Didinella bryoniae) The toxicity of mycelium and the effect of compounding agents with synergistic effects were measured on the prevention and treatment of cucumber cranberry disease. The results showed that the ratio of conoters, polymyabacteria, mycobacteria, fine meesti, fine mecoic, Fu Fu zinc and ketone-manganese zinc, which were further screened and compounded on the basis of the cosyme of Didynnella bryoniae, was further screened and compounded by the growth rate method. And the effect of compounding agentwith with synergy to determine its prevention and treatment effect on cucumber cranberry disease. The results showed that the EC50 of Fu Fu zinc and ketone-manganese zinc-to-melon cucumber cranberry bacteria were 16.166 sg-mL-1 and 58.740 sg-mL-1, respectively. When the ratio of compounding of Fu Fu zinc and copper and manganese zinc was 1:1 and 3:2, the efficiency value (SR) was 2,653.57 and 399.58, respectively, the synergy was significantly higher than the other ratios, and the effect of the two ratios of compounding agents on cucumber cranberry disease was 85.72% and 78.57%, respectively. Therefore, it can be shown that fu Fu zinc and copper manganese zinc compounding can improve the prevention and treatment effect of cucumber cranberry disease.

In order to find out the proportion of protective fungicides and endogenous fungicides and their control effect on cucumber vine blight, six fungicides including pyrimethyl ester, carbendazim, carbendazim, sperm methyl-trichloronitrile, fu-zinc and oxone-manganese-zinc were selected to determine the toxicity of six fungicides to the mycelia of Didynnella bryoniae, and the synergistic compound fungicides were tested. Control effect on cucumber vine blight. The results showed that six fungicides, pyrimidine ester, carbendazim, carbendazim, sperm-methyl-pyrrolidone, fu-zinc and oxone-manganese-zinc, were tested for their toxicity to the mycelia of Didynnella bryoniae by growth rate method. On the basis of their toxicity to the mycelia of Didynnella bryoniae, the proportion of fungicides with strong toxicity was further screened, and the control effect of the fungicides with synergistic effect was determined. The results showed that the EC50 of fu-fu-zinc and oxone-manganese-zinc on the mycelia of cucumber vine blight fungus were 16.166 g mL-1 and 58.740 g mL-1, respectively. The synergistic value (SR) was 2 653.57 and 399.58 when the ratio of fu-fu-zinc and cupric manganese-zinc was 1:1 and 3:2, respectively. The synergistic effect was significantly higher than that of other proportions, and the control effect of the two proportions on cucumber vine blight was 85.72% and 78.57%, respectively. Therefore, it can be concluded that the combination of fu-fu-zinc and cupric-manganese-zinc can improve the control effect of cucumber vine blight.<BR>
