Biological Information and Remarks
Bensulide is a preemergence, selective, soil-applied
herbicide for control of annual-grasses and some
0,0 -diisopropyl phos =
broadleaf weeds in some vegetable crops, and grass
and dichondra lawns. A small amount is absorbed by
with N -(2 mercaptoethyl)
roots of weeds, but little or none is translocated
upward to leaves. It inhibits the growth of weed
roots, but the mechanism of action is not known.
Bensulide is degraded slowly by microorganisms in
the soil. There is little loss from the soil surface by
volatilization, but there is a small amount of photo-
decomposition. There is little leaching in soil. Its
half-life in moist soil is 4 to 6 months.
Selective foliage treatment that controls a number of
broadleaf weeds and nutsedge by contact action in
3-isopropyl 1 H -2,1,3-
most turfgrasscs and many large-seeded legume
crops. Rain shortly after application may decrease
4(3 H )-one 2,2-dioxide
effectiveness. Little basal movement with foliar ap-
plication, but movement upward through xylem tis-
solution of sodium salt)
sue is rapid after root absorption. It inhibits the Hill
reaction, and thus interferes with photosynthesis.
