Crop and/or Non-Crop Registrations	Carrots, lettuce, onions, spinach, daffodils, gladioli, iris, tulips and ornamental nursery stock.
Sensitive Weeds	Annual broadleaf and grass weeds including purslane, chickweed, smartweed, carpetweed, false flax, annual bluegrass, crab grass, rye grass, stink grass and dodder.
Uptake and Translocation	Readily translocated to the leaves following root absorption. Vapours have been demonstrated to be absorbed by seeds and emerged dodder.
Basis of Selectivity	Rapid degradation in tolerant plants as well as soil adsorption.
Application Methods	Preemergence and directed postemergence in specified crops.
Residual Activity	Tightly bound to soil colloids. The rate of dissipation can vary greatly with microbial activity and moisture level. Both high soil temperature and excessive soil moisture increase the rate of dissipation.
Unique Characteristics	Use the lower rates on sandy or coarse-textured soils and the higher rates on clay or muck soils. Weed control is most effective when soil temperatures are below 16°C. The lower rate should be used when soil temperature is below 16°C. The soil must be moist for effective weed control.
