Abstract
Three site prep vegetation control systems were compared on two Piedmont and two Upper Coastal Plain sites. Systems were (1) a one-time site prep application of Chopper® GEN2™ 2, (2) a one-time application of Chopper® GEN2™ tank mixed with sulfometuron, and (3) two applications consisting of site prep with Chopper® GEN2™ followed by herbaceous weed control with Arsenal AC plus sulfometuron in March/April following planting. Each of these systems was repeated with a July/August, September, and October site prep timing. The third system, consisting of two applications, resulted in better pine response and vegetation control for site prep in July through September on Upper Coastal Plain sites. The first system, a onetime application of Chopper® GEN2™ , provided good weed control and pine growth on Piedmont sites. The sulfometuron tank mix did not improve vegetation control and had negative effects on pine growth on Piedmont sites.
