Acute toxicities of selected herbicides to fingerling channel catfish, Ictalurus punctatus.
A scan of the acute toxicities of eighteen common herbicides to one-year-old channel catfish (Ictalurus punctatus) was conducted. Herbicides causing less than 10% mortality in 48 hr at 10 ppm were: alanap, chloramben, 2,4-D acid, 2,4-D dimethyl amine salt, dalapon, diuron, DSMA, EPTC, fluometuron, metribuzin, monuron, MSMA, nitralin and 2,4,5,-T. The 96-hr LC50 values in pp6 for four nerbicides found toxic were: propanil, 3796; trifluralin, 417; bensulide, 379; and DNBP 118. The toxicity of Dyanap, a mixture of DNBP and alanap, was lower than that of DNBP; there was no apparent synergism between DNBP and alanap in the mixture.
