| Abstract/Contents: | "Because of the proximity to the major ports of New Orleans and Mobile, Mississippi is a high risk for the introduction of nonindigenous invasive plants. It is estimated that nearly 20% of the species in the state are nonindigenous, such as cogongrass (Imperata cylindrical (L.) Beauv.) a highly invasive, warm-season, perennial grass. It effectively chokes out other species forming dense, monotypic stands. In the fall of 2010, the Environmental Protection Agency approved the registration of several herbicide blends that contain aminocyclopyrachlor. Field trials were established in Forrest County, Mississippi in 2010 to evaluate the effectiveness of these blends for the treatment of cogongrass. Plot size for the cogongrass was 3.1 by 6.1 meters, with subplots sized 3.1 by 3.1 m. Two weeks prior to the initiation of the trial, the subplots were mowed to 12.7 cm. A backpack sprayer was used to apply the herbicides to the split-plots previously determined to receive early-summer applications. Herbicides applied were 120 + 40 g ai/ha aminocyclopyrachlor + metsulfuron methyl with 1% v/v MSO, 87 + 35 g ai/ha aminocyclopyrachlor + chlorsulfuron and 1% v/v MSO, 101 + 73 + 26 g ai/ha imazapyr + aminocyclopyrachlor + metsulfuron methyl and 1% v/v MSO, 315 g ai/ha aminocyclopyrachlor as a liquid and 1% v/v MSO, 315 g ai/ha aminocyclopyrachlor as a soluble granule and 1% v/v MSO, 140 + 1064 g ai or ae/ha aminocyclopyrachlor + 2,4-D amine and 1% v/v MSO, 140 + 280 g ai or ae/ha aminocyclopyrachlor + triclopyr ester and 1% v/v MSO, 840 g ai/ha imazapyr as a liquid and 1% v/v MSO, and 1120 g ae/ha potassium salt of glyphosate. A 0.5 liter shaker was used to distribute 840 g ai/ha imazapyr as a granule with calibration blanks to aid in even distribution. Evaluation of the plots began 1 month after initial treatment (MAIT) and continued until 4 MAIT. Each plot was evaluated monthly for control. Culm density and shoot height were evaluated at the time of application and at 4 MAIT. In the unmowed subplots, imazapyr liquid showed the significantly greatest visual control and the significantly greatest reduction in density of culms. In mowed subplots, the imazapyr granule, glyphosate, and impazapyr, aminocyclopyrachlor, and metsulfuron all showed significant visual control of cogongrass. Glyphosate and the imazapyr, aminocyclopyrachlor, and metsulfuron combination provided the significantly greatest reduction of culm density in the mowed subplots. The results show that aminocyclopyrachlor, when paired with imazapyr and mowing, can provide an acceptable level of control for cogongrass when applied in early summer. This will provide landowners with additional mean of combating this highly invasive plant." |
