Pencycuron Usage And Synthesis

Uses

Pencycuron is used for the control of diseases caused by Rhizoctonia solani and Pellicularia spp. in potatoes, rice (sheath blight), cotton, sugar beet, vegetables, ornamentals and turf. It can be applied to foliage or 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 specific control against fungicidal diseases (Rhizoctonia solani and Pellicularia) in potatoes, sugar beets, rice, cotton and ornamentals. Not currently registered in the U.S. Used in most European countries. There are more than 30 global suppliers.

Metabolic pathway

The metabolic profiles of pencycuron in fungus, hydrolysis, mammals, photodecomposition, plants, and soils are illustrated. Both tolerant and sensitive fungal species Rhizoctonia solani metabolize pencycuron to give cis- and trans-3-hydroxycyclopentyl pencycurons which are less active than pencycuron.

Degradation

Pencycuron is a very stable compound. Its DT₅₀ in water at pH 4 is 280 days and at pH values 7 and 9 the estimated DT₅₀ values are 22 and 17 years, respectively. It is photolysed in water and on soil surfaces.
