QUIK STATS (last updated Dec 10, 2013 )
NOTES ABOUT THIS BIOTYPE
the last year we`ve been working with several A. quitensis biotypes wich
were not controlled with usual dosis of glyphosate in agricultural fields.
We performed greenhouse studies comparing them with a known susceptible biotipe
and we found a very high level of resistance in three of the suspected
dose response experiments were carried on using a wide range of doses from 34
g. a.e/ha up to 17280 g e.a/ha. In all the suspected biotypes we
registered surviving plants even at the highest dose tested.
