Uses

MONALIDE is used to destroyweeds of crops such as carrots, celery, and parsley.

Definition

ChEBI: Monalide is an anilide.

Environmental Fate

Biological. In the presence of suspended natural populations from unpolluted aquatic systems, the second-order microbial transformation rate constant determined in the laboratory was reported to be 6 ′ 10–13 L/organisms-hour (Steen, 1991).
Soil. Probably degrades via ring hydroxylation and subsequent ring cleavage. Persistence in soil is limited to approximate 6–8 weeks (Hartley and Kidd, 1987). Under laboratory conditions, the half-lives in soil were 30, 48 and 59 days at pH 4.85,
