If an anaerobic tea is held for lon

If an anaerobic tea is held for longer than 24 hours, and oxygen allowed to diffuse back into the water over the course of several days to weeks, then the detrimental conditions can be alleviated. But it can take weeks to out-compete the human pathogens and decompose toxins produced during the anaerobic period. Can “brought-back” tea be beneficial? Yes, if the bacteria now growing in the tea are quite beneficial species. The likelihood that the beneficial fungi will still be present, and be growing, is just about nil, however. Control of many foliar fungal pathogens will be difficult, because the beneficial fungi that protect the plants from those pathogens will have been lost.
