- Abstract
R-25788 (2,2-Dichloro-<em>N,N</em>-diallylacetamide) was the most effective of six potential antidotes evaluated to counter corn (<em>Zea mays</em> L.) injury from the acetanilide herbicides alachlor, metolachlor, acetochlor, H-22234 (<em>N</em>- chloroacetyl-<em>N</em>(2,6-diethylphenyl)glycine ethyl ester), and H-26910 (<em>N</em>-chloroacetyl-<em>N</em>-(2-methyl-6-ethylphenyl)glycine isopropyl ester). The other potential antidotes in order of decreasing effectiveness were: R-29148 (2,2-dimethyl-5-methyl- dichloroacetyloxazolidine), NA (1,8-naphthalic anhydride), CDAA (2-chloro-<em>N,N</em>-diallylacetamide), Carboxin (2,3-dihydro-5-carboxanilido-6-methyl-1,4-oxathiin), and gibberellin (GA3). GA3 only partly relieved the stunting of corn caused by EPTC and metolachlor and did not prevent other herbicide injury symptoms, suggesting that the mode of action of EPTC and metolachlor is not to simply block GA3 synthesis. R-25788 protected corn equally well from acetanilide or EPTC injury.
