I saw in shop got two version, the usual green bottle roundup, and yellow bottle roundup transorb.

Whats the difference? I see a.i. type and % also same.

shopkeeper was a new practical student, she also don't know difference. Owner was going out somewhere.
Looking around in internet also I can't seem to find a reliable info. just marketing mumbo jumbo from Monsanto.

Anyone know?

edit: solved.
Transorb variant is premixed with surfactant, but not sold here anymore. Whatever left in store is old stock.
