Biological Information and Remarks
Applied as a foliage spray, mostly in mixtures with
2,4-D, for control of broadleaf weeds in turf and in
cereal crops. It is translocated, and mode of action is
similar to 2,4-D. Care should be taken to avoid
spray drift to susceptible ornamental and crop
plants. Herbicidally significant amounts persist in
soil for less than 1 month.
Growth regulator that provides foliar-growth and
seedhead suppression in turf. Does not suppress
N -[2,4-dimethyl-5-[(tri =
seedheads of bahiagrass. Has a short soil residual,
leaches slightly in soil, and is microbially decom-
($39.00/lb; 2S, water-soluble
Soil fumigant applied to moist, cultivated soil. Im-
mediately sprinkle irrigate to wet soil to depth where
sodium methyldithio =
activity is desired. Covering soil with air-tight cover
gives superior control. Kills germinating seeds, rhi-
zomes, roots, and stems of weeds in soil. It also kills
nematodes, plant disease organisms, and some in-
sects. It is often used as a preplanting treatment for
lawn grasses, ornamental beds, fruit trees, etc. Very
corrosive to mild steel and stainless steel. Metham
breaks down in soil by chemical means in 1 to 5
hours to methyl isothiocyanate. Planting may take
place 14 to 21 days after treatment.
