Provided is a plant tissue culture bacteriostatic (antiseptic) agent containing botanical fungicide. The bacteriostatic (antiseptic) agent comprises isothiazolinone, nisin and aqueous extracts of the Chinese herbal medicines of terminalia, groundsel and aromatic madder. When the bacteriostatic (antiseptic) agent is applied in plant tissue culture, 0.35 to 0.5% of the bacteriostatic (antiseptic) agent is added into a medium, which enables fungal and bacterial contamination to a culture to be effectively reduced or prevented and poses little adverse influence on plant growth, thereby enhancing the success rate of plant tissue culture; the bacteriostatic (antiseptic) agent can also be applied in open type plant culture, e.g., in the rooting phase of sound seedlings during a late plant culture stage, the bacteriostatic (antiseptic) agent is directly added into a medium, and the medium can be inoculated in indoor environment with bacteria or a few bacteria without undergoing the step of autoclaving or operating on a superclean bench, thereby simplifying seedling culture in plant tissue culture, enhancing working efficiency, saving a great amount of energy and reducing production cost for plant tissue culture seedlings; therefore, the bacteriostatic (antiseptic) agent has a critical actual application value.
