Automation of Dosing/ Chemigation

Can members tell me how well accepted would be an automated irrigation system that allowed automatic selection of perhaps as many as six different agrichemicals for injection/ dosing into lawn irrigation systems?

The only thing legal to inject into a irrigation system is liquid ferts. You can not use any pesticide\insecticide solution legaly. Also, as far as I'm aware, all pest\insect chemicals recommend that you don't use the irrigation system to apply these chemicals.

I have posted on this topic before. Take a look and see if you would do it.

It's actually

I haven't installed them and really don't like the idea.

I agree that in theory its a good idea. But what about:

Very few systems have equal coverage over the entire lawn.

Many plants don't require the same fert. analysis as the lawn.

You would still need to apply crabgrass control in the spring.

What about water features. How would you avoid these?

Over spray onto streets, even a little bit sends fert. into storm
sewers and eventually lakes and streams (bad PR).

Somebody would have to moniter and adjust heads often.
Even in the spring when the lawn looks great due mainly
to rain you could have a head not turning and that area
wouldn't get fertilized.

My experience is that most commercial customers don't have anyone in house capable of maintaining a system to the degree required. So they could pay a weekly or monthly fee to check
the system out or they could pay an LCO to come in and apply
the fertilizer. It's pretty obvious to me which option would be

This idea works well in ag applications because of one crop. Also ag field systems or green house system are can be built with much more uniformity in application.

In my opinion (and some fact), this idea doesn't translate well to commercial and residential landscapes even though it is being promoted.
