SIDURON Chemical Properties,Uses,Production
Chemical Properties
Colorless or white crystalline solid or powder. Odorless. Commercial product is available as an emulsifi- able concentrate.
Uses
Selective preemergence herbicide used to control annual weed grasses and prevent growth of crabgrass, foxtail and barnyard grass in turf, cereals and other food crops.
General Description
Siduron is a pre-emergence and post emergence phenylurea herbicide used for the control of annual grass weeds. Its mode of action involves the inhibition of photosynthesis.
Agricultural Uses
Herbicide: A pre-emergence herbicide used to control annual grasses, e.g., crabgrass, foxtail, and barnyard grass. Used on newly seeded or established turf and lawn grasses and as pre-emergence treatment to bare soil following spring seeding. Not listed for use in EU countries. Registered for use in the U.S.
Trade name
GREENFIELD®; GRO-TONE®[C]; H-1318®; TREY®; TUPERSAN®
Potential Exposure
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).
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.
