Effect of ethalfluralin and other herbicides on trifluralin-resistant green foxtail (Setaria viridis)


, : Effect of ethalfluralin and other herbicides on trifluralin-resistant green foxtail (Setaria viridis). Weed Technology 7(1): 6-14

The response of trifluralin-susceptible (S) and -resistant (R) S. viridis biotypes to herbicides belonging to several chemical groups was compared to determine the cross-resistance pattern of the R biotype.

Field trials were conducted on clay loam at Portage la Prairie in 1989-90 to determine the response of susceptible (S) and resistant (R) S. viridis biotypes to 0.25-3 kg/ha trifluralin, applied before sowing (PPI) in rape and soil-incorporated pre...

In a petri dish assay, radicle growth of trifluralin-resistant (R) green foxtail exposed to trifluralin concentrations of up to 0.4 ppm (w/v) was not inhibited. Radicle growth of trifluralin-susceptible (S) biotypes was completely inhibited. Shoot...

A trifluralin-resistant (R) biotype of Setaria viridis is found in areas of Manitoba, Canada where trifluralin is utilized as the principal or sole herbicide. In this study, we examine the cross-resistance pattern of this biotype to other mitotic...

In F2 progeny, derived from F1 hybrids, shoot growth of seedlings, measured 4 d after germination, distinguished susceptible (S) and resistant (R) phenotypes. Chi-square values indicated that the F2 data fit a 3:1 (S:R) ratio for both populations...

In the summer of 1995, green foxtail seed samples were collected from 17 fields in southwestern Manitoba where trifluralin resistance was first identified in 1988. Since 1988, six of these fields had not been treated with dinitroaniline herbicides...
