| dc.description.abstract | Ethofumesate as an emulsifiable concentrate (EC) formulation (Prograss*) demonstrated slightly more activity against Poa annua, though not statistically significant, than the suspension concentrate (SC) herbicide (PoaConstrictor*). Following two applications, P. annua control was equivalent for Prograss at 0.75 lb a.i./A and PoaConstrictor at 1.0 lb a.i./A at approximately one month later. Late season evaluations showed that Prograss at one-half the rate of PoaConstrictor gave acceptable P. annua control. Both products needed to be applied two times at 2.0 lb a.i./A to achieve better than acceptable P. annua control as spring transition occurred. | |
