Pencycuron Usage And Synthesis
| Uses | Pencycuron is used for the control of diseases caused by Rhizoctoniasolani and Pellicularia spp. in potatoes, rice (sheath blight), cotton,sugar beet, vegetables, ornamentals and turf. It can be applied to foliageor by incorporation into the soil. |
| Uses | Pencycuron is an urea based fungicide developed specifically against the plant pathogen Rhizoctonia solani for which it was developed. Pencycuron has also been used for controlling sheath blight of rice. |
| Uses | N-((4-Chlorophenyl)methyl)-N-cyclopentyl-N'-phenylurea is an urea based fungicide developed specifically against the plant pathogen Rhizoctonia solani for which it was developed. N-((4-Chlorophenyl)methyl)-N-cyclopentyl-N'-phenylurea has also been used for controlling sheath blight of ri ce. |
| Definition | ChEBI: A member of the class of ureas carrying 4-chlorobenzyl and cyclopentyl substituents at position 1 and a phenyl substituent at position 3. A fungicide used to control diseases caused by Rhizoctonia solani and Pellicularia spp. It i not highly toxic to mammals but is moderately toxic to birds, most aquatic organisms, honeybees and earthworms. |
| General Description | Pencycuron is a non-systemic phenyl urea herbicide effective against pathogens such as Rhizoctonia solani and Pellicularia spp. Pencycuron acts by inhibiting cell division. |
| Agricultural Uses | Fungicide: Pencycuron is a non-systemic fungicide with specificcontrol against fungicidal diseases (Rhizoctonia solani andPellicularia) in potatoes, sugar beets, rice, cotton and ornamentals.Not currently registered in the U.S. Used in mostEuropean countries. There are more than 30 global suppliers. |
| Trade name | BAY® NTN-19701; BAYER® NTN-19701;MONCEREN®; NTN-19701®; PENCYCURONE® |
| Metabolic pathway | The metabolic profiles of pencycuron in fungus,hydrolysis, mammals, photodecomposition, plants, andsoils are illustrated. Both tolerant and sensitive fungalspecies Rhizoctonia solani metabolize pencycuron togive cis- and trans-3-hydroxycyclopentyl pencycuronswhich are less active than pencycuron. |
| Degradation | Pencycuron is a very stable compound. Its DT50 in water at pH 4 is 280days and at pH values 7 and 9 the estimated DT50 values are 22 and 17years, respectively. It is photolysed in water and on soil surfaces. |
