Abstract
The use of biological agents in the control of the invasive weed velvetleaf Abutilon theophrasti is attractive due to this weeds development of herbicide resistance. One option is the utilization of deleterious rhizobacteria with amendments to optimize their effectiveness. Indole acetic acid (IAA)- producing Rhizobium rubi (AT3-4RS/6 (RS) and cyanogenic Pseudomonas putida ATH2-1RI/9 (RI) were used to inoculate soil with and without amino acid amendments. RS & tryptophan (a precursor of IAA synthesis) caused the least velvetleaf shoot growth. All roots were colonized by rhizobacteria, on average, 1.40E+10 CFU/ gram of dry root.
