If lines are not adequately flushed, there will be problems with anaerobic
activity and biofilm. This is less of a problem in agricultural drip systems
that are replaced yearly or with each cropping.
I am working with an injector company and we believe we have a horticulture
unit that will work. I still worry about poorly designed irrigation systems
and the potential for growing some nasties. The big problem with many
ornamental horticulture sites is high chlorine levels. I believe that I have
circumvented that problem with 10-25 times the amount of tea recommended. At
17 cents a gallon I don't find the expense disconcerting

I need to defer the answer about drip irrigation to others who know more
about this topic.
What I have learned is that you need to look at the size on the nozzle of
your emitter. They can be very small (5 micrometers) to large enough to let
any microbe pass (400 micrometers). You want the larger size nozzles,
probably not smaller than 200 micrometers. Testing is important to know if
the organisms are passing your nozzle.
Cleaning out the drip lines is necessary, and hydrogen peroxide and vinegar
are very good for cleaning the lines out.
Anyone else have experience on this that they can share?
