1-(5-tert-Butyl-1,3,4-thiadiazol-2-yl)-1,3-dimethylurea Chemical Properties,Uses,Production

Uses

Tebuthiuron is an nonselective broad spectrum herbicide used to control weeds, woody and herbaceous plants.

Uses

Herbicide.

Uses

Nonselective herbicide used to control herbaceous and woody plants on noncrop land.

Definition

ChEBI: Tebuthiuron is an organonitrogen heterocyclic compound and an organosulfur heterocyclic compound.

Production Methods

Tebuthiuron is produced commercially through a multi-step chemical synthesis that constructs its urea-based herbicidal structure. The process begins with the preparation of key intermediates such as substituted phenyl isocyanates and methylamines, which are reacted under controlled conditions to form the active tebuthiuron molecule.

General Description

Colorless odorless crystals. Non corrosive. Used as an herbicide.

Reactivity Profile

A urea, thiadiazole derivative.

Agricultural Uses

Herbicide: Tebuthiuron is a broad-spectrum herbicide that is used to control weeds in non-cropland areas, range lands, rights-of-way and industrial sites. In grasslands and sugar cane it controls woody and herbaceous plants and weeds such as alfalfa, bluegrasses, chickweed, clover, dock, goldenrod and mullein. Not approved for use in EU countries[ 115]. Registered for use in the U.S.

Trade name

BRULAN®; BRUSH-BULLET®; E-103®; GRASLAN®; HERBEC®; HERBIC®; PERFLAN®; RECLAIM; SHA-105501®; SPIKE®; SPRAKIL®; TEBULAN®; TIUROLAN®

Mechanism of action

Systemic, low selectivity, absorbed by roots and translocated. Inhibits photosynthesis (photosystem II).

Environmental Fate

Soil. In microbially active soils, tebuthiuron is degraded via demethylation. The average half-life in soil 12–15 months in areas receiving 60 inches of rainfall a year (Humburg et al., 1989).
When tebuthiuron was applied to a rangeland at a rate of 0.84 kg/ha, 38% remained after 21 months (Emmerich et al., 1984).
Groundwater . According to the U.S. EPA (1986) tebuthiuron has a high potential to leach to groundwater .
Plant. Degrades in plants via N-demethylation and hydroxylation of the t-butyl sidechain (Hartley and Kidd, 1987; Humburg et al., 1989).
