Abstract

Under greenhouse conditions activated carbon, applied as a slurry at the time of seeding, protected Italian ryegrass (Lolium multiflorum Lam.) seedlings from the toxicity of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) applied preemergence. Plants growing from seeds planted 1.3 cm deep received less protection from diuron than plants growing from seeds planted 0.6, 1.9, or 2.5 cm deep. Sandy loam soil required at least three times more activated carbon than a clay loam soil to obtain the same protection. Activated carbon applied at 130 kg/ha in a 2.5-cm band on the soil surface directly over the seeds provided adequate protection on a clay loam soil. On a sandy loam soil the 130-kg/ha rate was not adequate. Wetting agents added to aid in carbon wetting reduced the protective effect of activated carbon when added at 0.9 or 2.7% (v/v) but had only a slight effect on protection when added at 0.3% (v/v). The soil moisture level at the time of carbon application and the amount of subsequent irrigation did not influence the protection obtained with activated carbon.
