Microbial flora are hard to kill, in the sense of eradicating them all in the soil/media. But their ecosystem, all the interactions including with the plant, are complex and easier to disrupt.
Not having water, high or low temperatures or pH levels, toxic levels of nutrients (things that can kill the plants too) will kill and disrupt the microbes.
Every plant has its own external surfaces' microbial ecologies, whether you seed these with known good strains or rely on normal environmental contamination/colonization. The idea with Great White, a mixture of diverse microorganisms, and also more individual microbial component type products, such as Voodoo Juice (bacteria) and Tarantula (fungi), is to try to control the core composition/population of your plant-soil/media interface ecosystem by (re)inoculating or (re)seeding it with proven good strains. It's similar to eating yogurt to repopulate your lower digestive track with beneficial bacteria.
Yes, these products should be used in soil/media prep, transplanting, etc. But at least theoretically and in industrial bioprocessing, repeated reinoculation/redosing works best. You are essentially trying to maintain a chronic infection. After following initial instructions, a portion of a normal dose can serve as booster. For example, I just normally add about 1 mL/plant Voodoo Juice and often also Tarantula and Piranha with each feeding. Beneficial microbes are probably the most cost-effective (they actually work) additives around.
