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, 1966Although 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.

Photocatalytic degradation of the diuron pesticide
Environmental Chemistry Letters, 2007The occurrence of chlorinated pesticides in wellwaters is a major problem of public health in Ivory Coast and other African countries. Here, we studied the photocatalytic degradation of the pesticide diuron in aqueous solution in presence of two commercial TiO2 catalysts, P25 and PC500. The capacity of diuron adsorption at the TiO2 surface is lower for

Adsorption of Ametryne and Diuron by Soils
Weed Science, 1970The 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 ...

Diuron uptake by microbial biofilms
2017The biofilm is composed on microalgae and other microorganisms embedded in a polysaccharidic matrix (EPS). In this study, we used the model pesticide diuron, a photosynthesis inhibitor, one of the priority substances in the EU Water Framework Directive, and its main metabolites (DCPMU and DCPU).
