Penetration and Persistence of Diuron in Soil

Weeds, 1961
The selective control of weeds in crops by the use of 3–(3,4–dichlorophenyl)–1,1–dimethylurea (diuron) has had considerable attention the last five years. Some of the problems of applying diuron are how long and at what depths the herbicide remains in the soil after treatment, with different methods and amounts of irrigation.

Photochemical Degradation of Diuron and Monuron

Weeds, 1961
(ONSIDERABLE attention has been given during recent years to the . fate of herbicides sprayed onto soil surfaces. The effect of light upon herbicides also has been studied extensively. Payne and Fults by means of a biological test found that the potency of 2,4-D was increased by exposure to ultraviolet light (7).

Fate of Diuron and Linuron in a Field Lysimeter Experiment

Journal of Environmental Quality, 2006
ABSTRACTThe environmental fate of herbicides can be studied at different levels: in the lab with disturbed or undisturbed soil columns or in the field with suction cup lysimeters or soil enclosure lysimeters. A field lysimeter experiment with 10 soil enclosures was performed to evaluate the mass balance in different environmental compartments of the ...

Adsorption of Ametryne and Diuron by Soils

Weed Science, 1970
The adsorption of 2-(ethylamino)-4-(isopropylamino)-6-(methylthio)-s-triazine (ametryne) and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) varied greatly among 34 Puerto Rican soils was studied using the agitated slurry technique. Adsorption was expressed as a distribution coefficient (Kd), which is the ratio of the amount of herbicide adsorbed to ...

Transplacental transfer and metabolism of diuron in human placenta

Toxicology Letters, 2018
Diuron is a broad-spectrum phenylurea derived herbicide which is commonly used across the globe. Diuron is toxic to the reproductive system of animals and carcinogenic to rat urothelium, and recently found to be genotoxic in human cells. In in vivo, it is metabolized predominately into 3-(3,4-dichlorophenyl)-1-methyl urea (DCPMU) in humans and 3-(3, 4 ...

Residues of diuron and phytotoxic degradation products in aquatic situations. II. Diuron in irrigation water

Pesticide Science, 1978
AbstractWhen diuron is used as a soil‐residual herbicide in irrigation canals, water quality is protected in standard practice by ‘flushing’–the diversion of the first discharge of water to the drainage system before irrigation is resumed. In three canals treated with diuron at about 40–45 kg ha−1, flushing for 4 h was relatively inefficient, removing ...

Amiben and Diuron Preemergence in Castorbeans

Weeds, 1966
Although selectivity was low, 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) gave excellent preemergence weed control when castorbeans (Ricinus communis L.) were planted 2 or 3 in deep. Excellent weed control with little crop injury by 3-amino-2,5-dichlorobenzoic acid (amiben) was provided also and selectivity was not affected by depth of planting.
