SIDURON Chemical Properties, Uses, Production
Description
Siduron is a selective pre-emergence herbicide. It has a moderate aqueous solubility, is volatile and, based on its chemical properties, it is moderately mobile with has a high potential to leach to groundwater. It is persistent in both soil and water systems. It has a relatively low mammalian toxicity and would not be expected to bioaccumulate. It is classified as an irritant. It is not highly toxic to birds, is moderately toxic to fish, algae and honeybees.
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.
Definition
ChEBI: Siduron is a member of ureas.
Production Methods
The production of siduron typically begins with the synthesis of N,N-dimethylurea, which serves as a key intermediate. This compound is then reacted with 2,3-dihydro-1H-indene-1-carbonyl chloride or a similar indanone derivative under controlled conditions to form the final siduron molecule. The reaction involves nucleophilic substitution, where the urea nitrogen attacks the carbonyl carbon of the acid chloride, forming the desired urea linkage. The process may require solvent mediation and temperature control to optimise yield and purity.
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®
Mechanism of action
Selective, absorbed by roots and translocated. Photosynthetic electron transport inhibitor at the photosystem II.
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.
