mögliche Exposition
A phenyl urea preemergence herbicide used to control annual grasses (e. g., crabgrass, foxtail, and barnyard grass) and on newly seeded or established turf and lawn grasses and as bare soil treatment following spring seeding.
Environmental Fate
Soil. A fungus and two Pseudomonas spp. isolated from soil degraded siduron to form the major metabolites: 1-(4-hydroxy-2-methylcyclohexyl)-3-(p-hydroxyphenyl)urea, 1-(4- hydroxy-2-methylcyclohexyl)-3-phenylurea and 1-(4-hydroxyphenyl)-3-(2-methycyclohexyl)urea (Belasco and Langsdorf, 1969).
Plant. After 8 days following absorption in barley plants, no metabolites were detected (Splittstoesser and Hopen, 1968).
Versand/Shipping
UN2767 Phenyl urea pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3002 Phenyl urea pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Waste disposal
Incinerate in a unit with efflu- ent gas scrubbing. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
