I am not having a go or anything and 0.3L of Naceto is not the worst by any means, but I am fascinated by the move to more and more aggressive Pre-em graminicide sprays on ploughed ground and these are more general questions than in anyway aimed at you. I have a couple of customers who were screaming at me all autumn that their crops needed to be pre-emed come hell or high water, I asked why it had to be pre-em they couldn't say what they were chasing and why they needed pre-em, other than everyone else is doing it.
Pre emerge seems to me to be latest craze amoung agronomists, with stronger and more toxic, (to the crop) Graminicide herbicides.
Are growers getting that much trouble with grass weeds?
Or are agronomists selling people a belt and braces to cover their the own asses, because farmers demand clean crops and never worry about economics?
