Roundup Vista Plus

[Laggard]

What rate would you put on to kill this sized blackgrass please? Using rain water [emoji97]

450g/l active ingredient so I would go 2.5L/ha to get over the 1000g/l active per ha. You want to get it before it starts stem extension as it can be harder to kill then.

Stick some liquid urea in with it

2L/ha will kill that stone dead. Grasses are generally much more sensitive to glyphosate than BLWs. I would use an adjuvant mind as these days I would have my doubts about any glyphosate formulation, even a posh one. Validate to go with it.

We added x-change to our Roundup vista last Autumn as we have hard borehole water and it made it go a bit 'gloopy'(if there is such a word).
Used some later without x change at 1.6l/ha seems to have killed all the weeds.
Was told Vista doesn't need a water conditioner.

Ammonium sulphate used to be the kiddie. Arma? Not sure of the spelling, used to make it hot as hades.

Have you had your borehole water analysed? Even the best glyphosate formulations will do better with water conditioners for anything harder. X Change needs to be added slowly as the tank fills - chucking it in first creates an oily scum in the tank that doesn't go away.

I had very hard mains water. I set up a Dosatron on a separate tank for conditioned water at the right concentration. If you buy an IBC of Aquascope (same as X Change) from Frontier, they will give you the Dosatron free. I used the treated water for generic glyphosate, hormones & SU herbicides, pyrethroid insecticides
