Yes good move. Anyone using chems should be trying to improve efficiency, regen or conventional.

With glyphosate we use

1% sulphate of ammonia

0.15% citric acid

40-100g/ha fulvic acid powder. (Liquid versions vary in strength)

0.2% wetter

Rain water where possible. Lower water rates help if water isn’t great. We settle tanks with aluminium sulphate to reduce hardness and have a reverse osmosis machine coming.

I can’t comment of reduction of rates but id say were 20% lower at least than most. You will have to work that one out for your own situation.

Certainly interested in impacts of structured water on foliars, that’s a very interesting topic 🙂
