Urumqi-changji Area Greenhouse And Field Investigation Of Bacterial And Fungal Diseases Of Vegetable

For discussion Changji area greenhouse and the field vegetable bacteria sexual and thefungi sexual disease of occurred and popular, this to Changji vegetable field and thegreenhouse, peace Canal field, Xishan greenhouse, Urumqi North Park Spring grocer ofvarious vegetable for experiment material, on various vegetable disease of occurred situationfor has investigation and in laboratory separation identification, obtained has pathogensstrains, and according to separation property of pathogenic sexual, and biology characteristics,and training traits, for has experiment research。Identification of bacterial diseases according to the results in the greenhouse and field inUrumqi-Changji area mainly cabbage, bacterial soft rot of cabbage and other vegetables,potato bacterial ring rot, bacterial angular leaf spot of cucumber diseases. According to referto the relevant documentation, access to strains of pathogenic bacteria in the laboratory forstudying all these vegetables are soft rot pathogens Erwinia uredovora carrot carrotsubspecies；Bacterial ring rot of potato pathogens for the thick-walled bacteria prokaryotesterritories rod-shaped bacteria are bacteria pathogen of bacterial angular leaf spot of cucumberfor the thin-walled bacteria genus Pseudomonas bacteria；Identification of the fungal diseases revealed, lettuce, leafy vegetable downy mildewSclerotinia blight, leaf blight of celery, lettuce downy mildew, root rot, kidney bean rust,Cowpea cucumber powdery mildew, verticillium dahliae, tomato early blight, powderymildew of pepper10kinds of fungal diseases. According to reference related of literatureinformation, will obtained of pathogens strains respectively determines for lettuce disc stemmold, and child SAC bacteria Asia door nuclear disc bacteria is, and half known bacteria Asiadoor shell needle spore is, and lettuce disc stem mold is, and half known bacteria Asia doorfungi sickle spore mold is, and burden bacteria warts top single cell rust bacteria is, and childSAC bacteria Asia door powder bacteria is, and half known bacteria Asia door fungi of largeLi round branch bacteria is, and half known bacteria Asia door chain cells spore is.Control studies have shown that high ridge cultivation to avoid fall vegetable such ascabbage, cabbage, radish seeds in low-lying, heavy viscosity of land. Onset heavy plot3yearrotation should be implemented, preferably with legume and vegetable diseases in vegetablecrop rotations can effectively reduce；Streptomycin72%pesticides, anti-bacterial agents used"401", Chloramphenicol can be effective in controlling bacterial diseases of vegetables. Withfour jinleiduomier,58%sum of manganese-zinc,20%triadimefon emulsifiable concentrate,five suspensions are effective in controlling fungal diseases of vegetable sulfur.
