Carfentrazone was applied in combination with imazapyr alone and three-way mixes with imazapyr and glyphosate to evaluate efficacy of natural pine control during site preparation activities. Results from four sites (two in MS, and one each in TX and SC) indicated that carfentrazone could assist in the control of small pine seedlings (less than six inches tall), but the control provided was not at a level considered acceptable for operational purposes. Larger pine seedlings (greater than one foot tall) were not adequately controlled by any of the treatments and shielding by other vegetation was an important factor in the control of smaller pine seedlings. Carfentrazone is not labeled for use in forestry applications and results from this study did not provide any rationale for pursuit of such labeling.
