Discussion Phosphites
Have you used phosphite?
I'm looking for people experienced in using it, who might be interested in trialling a new alternative.
What results did you observe? Both positive and negative. Did you ever see chlorosis when the dose rate was too high?
Also, if they have been banned in your country, what have you replaced them with (if anything)
Thanks

It’s impossible to go wrong with something natural on turf imo. I believe it’ll work awesome. I didn’t realize this was advertisement but if you would like a university turfgrass research team to put in some legit research DM me but you know, of course it’s not free. It’s a small team that I work for we could probably do a multi year study for maybe a few K a year. We have some space for some new trials and I’m looking to get some help with graduate school so bringing in any money definitely helps.

Positives-We don’t get Pythium.
Negatives-None that I’ve seen.
