The method has the advantages of low price, accuracy in determination, strong operability, easiness in promotion and application, and provision of effective basis for field safety production management.

The invention provides a Pseudomonas.chlororaphis subsp.Aurantiaca Pa40, preservation number of which is CGMCCNo.2764. The strain generates HCN, prolease and siderophore relative to antibacterium and has plate board inhibition effect on a majority of tested plant pathogenic fungi and a part of tested plant pathogenic bacteria. Control effect of the biocontrol strain Pa40 on rhizoctonia solani is detected by taking wheat as an indicator plant on the plate, in the greenhouses and in the fields; a result shows that the control effects of the Pa40 on the rhizoctonia solani on the plate bed, in the greenhouse and in the fields are respectively 53.97%, 68.10% and 72.46%; wherein the control effects on the rhizoctonia solani in the greenhouses and fields are higher than that of validamycin.

The invention relates to a method for culturing and planting seedlings of color virus-free sweet potatoes. The method is characterized by utilizing the characteristic of low virus content or no virus content in stem tips of the sweet potatoes, cutting meristems of the stem tips of 0.2-0.4mm under an aseptic manipulation, forming test tube seedlings by culturing on a specific culture medium, and further detecting the virus-free seedlings by serology and indicator plant grafting. Meanwhile, the invention further provides the corresponding tissue rapid propagation technical regulations and a factorized production system according to different types, thereby accelerating the propagation of a large number of color style virus-free sweet potato seedlings. The method can propagate the potato species which has high nutritional value and bright color and is applicable to fresh-eating, baking or processing of the preserved sweet potatoes.
